Description

  Embodiments described herein relate generally to an air conditioning control system, an air conditioning control method, and a program.

  When an air conditioner is used in a space such as an office or a residence, the temperature or the like may be set with priority on efficient use of energy (energy saving). In such a case, it may be an unpleasant situation of being hot or cold for the user, and the possibility of allowing the user to accept the set value may be reduced. On the other hand, when the user sets the temperature of the air conditioner to an arbitrary value, sufficient energy saving may not be achieved.

In recent years, a technology has been proposed that obtains building structure data and room temperature data, divides the space in the building, estimates the temperature change in each space, calculates the air conditioning control amount based on the estimation result, and controls the air conditioning. Yes. In addition, the heat load in the building is estimated using the amount of power generated by the solar power generation device, the power consumption of home appliances, the location information thereof, the occupancy information of the occupants and the location information thereof, and air conditioning is performed based on the estimation results. Control techniques have been proposed. In addition, a technique has been proposed in which feedback on the room temperature from the occupants is reflected and reflected in the air conditioning control.
However, in these methods, control is performed toward one target temperature value set in advance in the system, or the target temperature value is controlled with one type of pattern for the total feedback value. However, there are cases in which it cannot follow the change in the thermal sensation of the occupant and cannot always be said to be comfortable for the occupant.

  Hereinafter, an air conditioning control system, an air conditioning control method, and a program according to embodiments will be described with reference to the drawings.

(First embodiment)
FIG. 1 is a functional block diagram illustrating the overall configuration of an air conditioning control system 100 according to the first embodiment. The air conditioning control system 100 performs indoor air conditioning control based on the collected indoor and outdoor thermal load conditions. The air conditioning control system 100 acquires, for example, information (for example, outside air temperature) indicating the indoor and outdoor heat load status from a building energy management system (hereinafter referred to as “BEMS”) 200.

  The air conditioning control system 100 is realized by a device including, for example, a CPU (Central Processing Unit) and a RAM (Random Access Memory). The air conditioning control system 100 functions as a scene determination unit 101, a cycle determination unit 102, an instruction condition determination unit 103, an instruction value determination unit 104, an instruction unit 105, and a set temperature history value management unit 106 by executing an air conditioning control program. To do. The air conditioning control system 100 may be constructed in an information processing apparatus such as a server or a personal computer, or may be included in the BEMS 200. The air conditioning control system 100 may be constructed on a cloud computing system. The air conditioning control system 100 may be configured on any other system.

  The scene determination unit 101 determines a use scene of the air conditioning control area at a predetermined timing based on the sensing information. Sensing information is information regarding the usage status of an air conditioning control area whose temperature is controlled by the air conditioner. The sensing information is, for example, the amount of power used and the amount of heat generation fluctuation. Sensing information is an aspect of indoor environment information. When the scene determination unit 101 determines a usage scene, the scene determination unit 101 acquires an average value of sensing information collected a predetermined time. The predetermined time may be 1 hour, 30 minutes, or 2 hours. The predetermined time may be any amount of time. The amount of power used is the amount of power used by devices arranged in the air conditioning control area. The scene determination unit 101 acquires an activity amount fluctuation amount from the heat generation amount estimation unit 202. The amount of activity fluctuation is determined based on the number of people in the air conditioning control area or the room temperature. The predetermined timing may be, for example, once a day or twice a week. The predetermined timing may be any timing. The air conditioning control area is an area where the air conditioner 400 performs temperature control. The use scene represents a method of using an air conditioning control area such as general desk work, a window or a reception. The use scene is information for determining a cycle for accepting the intention to review the set temperature in the air conditioning control area.

  The cycle determination unit 102 determines a cycle for accepting a set temperature review intention of the air conditioner 400 based on the usage scene determined by the scene determination unit 101 and the number of people information at the current time. The cycle determination unit 102 acquires the number of people information in the air conditioning control area from the number of people determination unit 203. The intention to review the set temperature is an evaluation of the environment of the air conditioning control area collected from a person in the air conditioning control area. The start and end times of the period for accepting the set temperature review intention are referred to as the review time. The review time is determined by the period determination unit 102 based on the determined period. The next review time is determined based on the cycle determined by the cycle determination unit 102 at each review time. The review time is a time at which the set temperature review intention from the feedback unit 300 is set to an initial value, and the time between two successive review times is a time at which the set temperature review intention from the feedback unit 300 is accepted. is there. The intention to review the set temperature from the feedback unit 300 is given as a feedback evaluation value. The review time determined by the period determination unit 102 is set in the instruction condition determination unit 103 and the instruction value determination unit 104. The initial setting value of the review time may be a numerical value set in advance in the system, or may be configured so that the system administrator can arbitrarily change it.

  The instruction condition determination unit 103 determines the first temperature control condition based on the outdoor environment information acquired from the outdoor environment detection unit 204 at each review time. The outdoor environment information is information related to the environment outside the air conditioning control area. The outdoor environment information is, for example, the outside air temperature and the amount of solar radiation. The instruction condition determination unit 103 acquires outdoor environment information from the outdoor environment detection unit 204. The first temperature control condition defines specific signs and numerical values related to the direction and width in which the set temperature of the air conditioner 400 is changed. The instruction condition determination unit 103 is an aspect of the control condition determination unit. The first temperature control condition is an aspect of the temperature control condition.

  The instruction value determination unit 104 determines a feedback evaluation threshold based on the usage scene determined by the scene determination unit 101. The feedback evaluation threshold is used for the instruction value determination unit 104 to determine whether or not to output a temperature control instruction. For example, when the feedback evaluation value received from the feedback unit 300 exceeds the feedback evaluation threshold, the instruction value determination unit 104 outputs a temperature control instruction to the instruction unit 105. The temperature control instruction is output only once at the interval between the review time and the review time. The temperature control instruction includes a set temperature value determined based on the current set temperature value acquired from the set temperature history value management unit 106 and the first temperature control condition received from the instruction condition determination unit 103. . Specifically, the new set temperature value is determined by adding the first temperature control condition received from the instruction condition determination unit 103 to the current set temperature value acquired from the set temperature history value management unit 106. The feedback evaluation threshold is one aspect of the first threshold for the intention to review the set temperature.

  The instruction value determination unit 104 updates the feedback evaluation value received from the feedback unit 300 at the review time determined by the cycle determination unit 102 and sets it to an initial value. For example, the initial value of the feedback evaluation value may be 0, or may be a numerical value preset in the system. During the time between two successive review times, the feedback evaluation value received from the feedback unit 300 is integrated as a set temperature review intention. The initial value of the feedback evaluation value may be configured so that the system administrator can arbitrarily change it.

  The instruction value determination unit 104 instructs the instruction unit 105 to reset at a predetermined timing. The reset instruction is an instruction to change the set temperature of the air conditioner 400 to the initial set temperature. The predetermined timing may be twice a week (for example, Wednesday and Sunday), or any timing. The predetermined timing may be defined according to the usage mode of the air conditioning control area. The instruction value determination unit 104 determines an initial set temperature of the air conditioner 400 that is instructed by a reset instruction. As the initial set temperature, a preset set temperature may be used, or the instruction value determination unit 104 acquires the set temperature up to a time that is a predetermined time back from the set temperature history value management unit 106 and obtains the current time It is good also considering the average value or minimum value of the temperature control instruction output retroactively from the set period as the set temperature. The predetermined period may be one day, one week, or from the time when the previous reset instruction was issued to the current time.

  The instruction unit 105 sets a set temperature in the air conditioner 400 based on the temperature control instruction or the reset instruction received from the instruction value determination unit 104. The instruction unit 105 records the set temperature registered in the air conditioner 400 based on the temperature control instruction in the set temperature history value management unit 106.

  The set temperature history value management unit 106 may be configured using a storage device such as a magnetic hard disk device or a semiconductor storage device, or may be configured using a relay device capable of information communication with the BEMS 200 or an external storage device. Alternatively, it may be configured by a program reference file. The set temperature history value management unit 106 stores the set temperature set in the air conditioner 400 by the instruction unit 105 in itself or an external storage device or file, and acquires the set temperature history value stored in itself or the external storage device. To the indicated value determination unit 104.

  The BEMS 200 is executed by a device including a CPU and a RAM, for example. The BEMS 200 functions as an electric energy detection unit 201, a calorific value estimation unit 202, a person number determination unit 203, and an outdoor environment detection unit 204 by executing a building management program. The BEMS 200 may be constructed in an information processing apparatus such as a server or a personal computer. The BEMS 200 may be built on a cloud computing system. The BEMS 200 may be configured on any other system.

  The electric energy detection part 201 calculates | requires the electric energy of the apparatus arrange | positioned in an air-conditioning control area. The power amount detection unit 201 outputs the used power amount to the scene determination unit 101. Examples of the device include an information processing device such as a personal computer or a server, or a business processing device such as an MFP multifunction peripheral or a shredder. The used electric energy may be aggregated from software built in the device, or may be acquired from an electric power meter that measures the used electric energy of the device.

  The calorific value estimation unit 202 calculates the calorific value fluctuation amount based on sensing information such as the number of people information and room temperature information. The heat generation amount estimation unit 202 outputs the heat generation amount fluctuation amount to the scene determination unit 101. The number of persons information is information obtained based on the number of persons existing in the air conditioning control area. For example, the number of persons is determined by a behavior estimation engine that estimates the amount of occupant activity based on the detection signal amount of an infrared human sensor. For example, the number of people obtained from a single sensor such as an image human sensor may be used as the number of people information. The number information managed by an entrance management system or a number counting device may be used as the number information. The room temperature information is information obtained based on the room temperature in the air conditioning control area. As the room temperature information, a room temperature change amount in which a change with time of room temperature is recorded may be used. What is necessary is just to determine the heat_generation | fever fluctuation amount from the heat load for the number of people, for example. A heat load per person may be prepared for each room temperature, and the heat generation fluctuation amount in the air conditioning control area may be determined by multiplying the acquired number of people. In addition, the heat load per person may be further divided according to the season, such as summer, winter, and the middle period, and the heat load per person may be further increased by time period such as morning, noon, and afternoon. Cases may be divided. The amount of fluctuation in heat generation may be determined from the level of room temperature change during a predetermined period, for example. The predetermined period is, for example, 30 minutes or 2 hours. For example, when the absolute value of the room temperature change amount exceeds 1 ° C. within 30 minutes, which is a predetermined period, the heat generation fluctuation amount is defined to be large. For example, when the absolute value of the change in room temperature is less than 2 ° C. within 2 hours, which is a predetermined period, the heat generation fluctuation amount is defined as small. The system administrator may arbitrarily change the thermal load per person for each room temperature, specific numerical values for a predetermined period, and the threshold value for determining the magnitude of the room temperature change amount.

  The number determination unit 203 determines the number of people in the air conditioning control area based on the number information. The number-of-people determination unit 203 may acquire the number of people from the behavior estimation engine that estimates the number of people in the room based on the detection signal amount of the infrared human sensor, for example. The number-of-people determining unit 203 may use the number of people obtained from a single sensor such as an image human sensor, for example. The number determination unit 203 may use the number of people managed by an entrance management system or a number counting device. The number-of-people determining unit 203 may use an instantaneous value at the time of program execution as the number of people information, or may use an average value for a fixed time retroactively from the time of program execution. When the average value is used, the time interval for calculating the average value may be configured so that the system administrator can arbitrarily change it.

  The outdoor environment detection unit 204 collects outdoor environment information. The outdoor environment detection unit 204 outputs the outdoor environment information to the instruction condition determination unit 103. In the first embodiment, the outdoor air temperature and the amount of solar radiation are used as the outdoor environment information, but any other information may be used. As the outdoor environment information, for example, PV (Photovoltaics) power generation amount or outdoor illuminance information may be used instead of the solar radiation amount. As the outdoor environment information, for example, the outside air humidity may be used instead of the outside air temperature. Data collected from environmental sensors installed in the same building may be used as outdoor environment information, or data acquired from environmental sensors installed in areas close to the air conditioning control area or from the Japan Meteorological Agency or external databases. May be used.

  The feedback unit 300 receives the opinions of the occupants regarding the temperature in the air conditioning control area. The opinion of the resident is digitized as a feedback evaluation value and output to the instruction value determination unit 104. The feedback unit 300 is an information processing apparatus such as a personal computer. In the case of a place where a specific person such as an office gathers, the feedback unit 300 is arranged at an employee seat in an air conditioning control area, for example. In the case of a place where unspecified people gather, such as a department store or a station, the feedback unit 300 is arranged, for example, at the entrance of a facility. The feedback unit 300 may be a program executed on an information processing apparatus such as a smartphone or an information processing apparatus. The feedback unit 300 may be configured not to accept an opinion from the same person a plurality of times within a certain time.

  A case where the feedback unit 300 is an apparatus managed by a system administrator and the identity of the sender of the opinion input to the feedback unit 300 cannot be specified or limited will be described. When feedback unit 300 receives an opinion, feedback unit 300 may not receive the next input for a predetermined time. The predetermined time is, for example, 3 seconds. The predetermined time may be configured to be arbitrarily changed by the system administrator. The device managed by the system administrator is, for example, a button, digital signage, tablet, or personal computer installed in a public place such as a department store. Note that the instruction value determination unit 104 may be configured to receive an opinion instead of the feedback unit 300.

  A case where the identity of the sender of the opinion input to the feedback unit 300 can be specified or limited will be described. The feedback unit 300 may receive opinions from a specific person not only once but a plurality of times within a predetermined period. For example, the feedback unit 300 may accept opinions from the same person up to twice within one hour. Further, when the feedback unit 300 receives an opinion, it is not necessary to receive an input from the same person for a predetermined time. The predetermined time is, for example, 15 minutes. The predetermined time interval and the predetermined time may be configured so that the system administrator can arbitrarily change them. The specific person is, for example, a person identified by a login account for a website or application functioning as the feedback unit 300, a person using an assigned dedicated booth, or the like. Note that the instruction value determination unit 104 may be configured to receive an opinion instead of the feedback unit 300.

  The air conditioner 400 controls the temperature in the air conditioning control area to the set temperature. The set temperature of the air conditioner 400 is changed to the set temperature set from the instruction unit 105. The air conditioner 400 may have a plurality of air conditioning control areas. When the air conditioner 400 has a plurality of air conditioning control areas, the air conditioning machine 400 may have a set temperature for each air conditioning control area. The air conditioner 400 may control an environment (for example, humidity) other than temperature.

  FIG. 2 is a diagram illustrating a specific example of a parameter table for determining a use scene according to the first embodiment. The usage scenes are classified into four usage scenes according to the level of power consumption and the level of heat generation fluctuation. For example, when the amount of power used is high and the amount of generated heat fluctuation is low, the scene determination unit 101 determines the usage scene as A (for example, a general desk work in a normal office or a telephone call reception work in a call center). Similarly, when the amount of power used is low and the amount of heat generation fluctuation is low, the scene determination unit 101 determines the usage scene as B (for example, during a lunch break or during a lecture in a conference room). Similarly, when the amount of power used is high and the amount of heat generation fluctuation is high, the scene determination unit 101 determines the usage scene as C (for example, an active office work at a financial exchange, a television broadcasting station, or a newspaper company). To do. Similarly, when the amount of power used is low and the amount of heat generation variation is low, the scene determination unit 101 determines the usage scene as D (for example, work in a reception or a mail room). The high and low thresholds relating to the amount of power used and the amount of heat generation variation may be any numerical value defined by specific numerical values, and may be configured to be arbitrarily changed by a system administrator. The threshold value may be three or more levels instead of two levels. A plurality of usage scenes may be determined per day. The parameter table for determining the usage scene may be defined for each building or may be defined for each use of the building.

  FIG. 3 is a diagram illustrating a specific example of a parameter table for determining a use scene according to the first embodiment. For example, when the power consumption is 15 kWh or more and the calorific value fluctuation amount is less than 1 kW, the scene determination unit 101 determines the usage scene as A (for example, a general desk work in a normal office or a call reception work in a call center). Similarly, when the amount of power used is less than 15 kWh and the amount of generated heat fluctuation is less than 1 kW, the scene determination unit 101 determines the usage scene as B (for example, during a lunch break and listening to a lecture in a conference room). The amount of power used may be the amount of power used for a certain period of time that has been traced back from the time of determining the usage scene. The calorific value fluctuation amount may also be an average value of the calorific value fluctuation amount for a fixed time that goes back from the time when the use scene is determined. Or you may utilize the emitted-heat amount fluctuation amount at the time of determining a utilization scene.

  FIG. 4 is a diagram illustrating a specific example of a cycle for determining the review time according to the first embodiment. The period is classified into 8 patterns depending on the usage scene and the number of people information. For example, when the usage scene is A and the number of people information is large, the cycle determination unit 102 determines the cycle as “short”. “Short” indicates, for example, that the period that is the interval of the review time is 30 minutes. Similarly, when the usage scene is A and the number of people information is small, the cycle determination unit 102 determines the cycle to be “long”. “Long” represents, for example, that the period, which is the interval between review times, is 2 hours. Here, the specific numerical values of “short” and “long” may be any defined numerical values, and may be configured to be arbitrarily changed by the system administrator. The threshold value of the number of people information is not two steps, but may be three or more steps, or may be different depending on the day of the week, business day, regular holiday, season, or the like.

  FIG. 5 is a diagram illustrating a specific example of a cycle for determining the review time according to the first embodiment. For example, when the usage scene is A and the number information is 10 or more, the cycle determination unit 102 determines the cycle, which is the review time interval, as 30 minutes. Similarly, when the usage scene is A and the number information is less than 10, the period determining unit 102 determines that the period that is the review time interval is 2 hours. The pattern of the period for determining the review time may be defined for each building or may be defined for each use of the building.

  FIG. 6 is a diagram illustrating a specific example of the first temperature control condition according to the first embodiment. The first temperature control condition in the first embodiment is classified into six patterns according to the outside air temperature and the amount of solar radiation. For example, when the outside air temperature is high and the amount of solar radiation is high, the instruction condition determination unit 103 determines that the temperature control instruction condition is “large”. “Large” represents, for example, that the control of lowering the set temperature of the air conditioner 400 by 1.5 ° C. in the case of cooling control system operation. Similarly, when the outside air temperature is high and the amount of solar radiation is low, the instruction condition determination unit 103 determines that the temperature control instruction condition is “medium”. “Medium” represents, for example, control for lowering the set temperature of the air conditioner 400 by 1 ° C. in the case of cooling control system operation. Here, the specific numerical values of “large”, “medium”, and “small” may be any numerical values defined, and all six patterns may be different values. Further, the numerical value may be configured so that the system administrator can arbitrarily change it. The threshold value of the amount of solar radiation may be three or more stages instead of two stages of high and low, and the threshold value of the outside air temperature may be four or more stages instead of three stages.

  FIG. 7 is a diagram illustrating a specific example of the first temperature control condition according to the first embodiment. For example, when the outside air temperature is 30 ° C. or more and the amount of solar radiation is 2 MJ / m 2 or more, the instruction condition determination unit 103 instructs control to lower the set temperature of the air conditioner 400 by 1.5 ° C. when the cooling control system is operated. The value is output to the value determining unit 104. Similarly, when the outside air temperature is 30 ° C. or higher and the amount of solar radiation is less than 2 MJ / m 2, the instruction condition determination unit 103 performs control to lower the set temperature of the air conditioner 400 by 1 ° C. when operating the cooling control system. The data is output to the determination unit 104. The first temperature control condition is preferably defined in each of the cooling control and the heating control. Moreover, you may each define by the place of an air-conditioning control area. When defined for each air conditioning control area, the air conditioning control area with many windows and the control area adjacent to the entrance / exit are easily affected by outdoor environment information, and the control area away from the entrance / exit without windows. The temperature can be managed by absorbing the difference of each air-conditioning control area that is not easily affected by the outdoor environment information.

  FIG. 8 is a diagram illustrating a specific example of the feedback evaluation threshold according to the first embodiment. The feedback evaluation threshold is classified according to the usage scene. In the first embodiment, four usage threshold values are classified according to four usage scenes. For example, when the usage scene is A, the instruction value determination unit 104 determines that the feedback evaluation threshold is “low”. “Low” is, for example, when the feedback evaluation value received from the feedback unit 300 is larger than the numerical value specifically determined as “low”, the instruction value determination unit 104 acquires the current value acquired from the set temperature history value management unit 106 The set temperature value determined based on the set temperature and the first temperature control condition received from the instruction condition determination unit 103 is output to the instruction unit 105. Similarly, when the usage scene is C, the instruction value determination unit 104 determines that the feedback evaluation threshold value is “medium”. In this case, when the feedback evaluation value received from the feedback unit 300 is larger than a numerical value specifically determined as “medium”, the instruction value determination unit 104 determines the current set temperature acquired from the set temperature history value management unit 106. The set temperature value determined based on the first temperature control condition received from the instruction condition determination unit 103 is output to the instruction unit 105. Similarly, here, the specific numerical values of “low” and “medium” may be any defined numerical values, and may be configured to be arbitrarily changed by the system administrator. The feedback threshold value may be three or four stages instead of two, or may differ depending on the day of the week, business day, regular holiday, season, or the like.

  FIG. 9 is a diagram illustrating a specific example of the feedback evaluation threshold according to the first embodiment. For example, when the usage scene is A, the instruction value determination unit 104 sets the feedback evaluation threshold value to 25. When the feedback evaluation value received from the feedback unit 300 is greater than 25, the instruction value determination unit 104 receives the current set temperature acquired from the set temperature history value management unit 106 and the first temperature control received from the instruction condition determination unit 103. The set temperature value determined based on the condition is output to the instruction unit 105. Similarly, when the usage scene is C, the instruction value determination unit 104 sets the feedback evaluation threshold value to 50. In this case, when the feedback evaluation value received from the feedback unit 300 is larger than 50, the instruction value determination unit 104 receives the current set temperature acquired from the set temperature history value management unit 106 and the first received from the instruction condition determination unit 103. A set temperature value determined based on one temperature control condition is output to the instruction unit 105.

  FIG. 10 is a diagram illustrating a specific example of an image displayed to the user in the feedback unit 300 according to the first embodiment. The feedback unit 300 according to the first embodiment receives the opinions of the occupants with, for example, three patterns of letters and colors of “hot”, “just right”, or “cold”. The feedback evaluation values correspond to the opinions of the occupants of the three patterns. A region 500 is a specific example of an image displayed to the user in the feedback unit 300. The user inputs an opinion by selecting characters and colors or icons in the areas 501 to 503 included in the area 500. For example, when the area 501 is selected, an opinion of “hot” is input, and the feedback evaluation value is added as “+1”. When the area 502 is selected, an opinion of “just right” is input, and the feedback evaluation value is added as “0”. When the area 503 is selected, an opinion of “cold” is input, and the feedback evaluation value is added as “−1”. When each area is selected once, a specific amount to be added is defined by a numerical value, and is added in a plus or minus direction. In addition, in order to prevent the “just right” effect from diminishing, the number of times that all areas are selected is counted separately as the total number of times received, and the result of addition is averaged by the total number of opinions received as a feedback evaluation value. You may define

  FIG. 11 is a diagram illustrating a specific example when the cooling control system according to the first embodiment is operated in a public place for one day. When the cooling control system is operated in a public place, scene discrimination is performed once a day. The scene determination unit 101 determines a use scene at 9 o'clock every day. The determined usage scene is used until the next usage scene determination time. The scene determination unit 101 determines a usage scene based on an average value of sensing information collected retroactively for a predetermined time. Based on the determined usage scene, the instruction value determination unit 104 determines a feedback evaluation threshold value. In the example of FIG. 11, 9 o'clock is the review time. Therefore, the cycle determination unit 102 determines a cycle for determining the next review time based on the number of people information received from the number of people determination unit 203. In the example of FIG. 11, it is determined that the period from 9 o'clock to the next review time is 30 minutes, and the review time continues at a 30 minute period of 9:30, 10 o'clock,. In the example of FIG. 11, the period from 17:30 to the next review time changes to 2 hours. Therefore, the review time continues in a two-hour cycle of 19:30, 21:30,. The review time and the use scene determination time do not necessarily have to be the same time, but it is desirable that the period, which is the interval until the next review time, is determined again according to the update of the use scene.

  In the cooling control system, the feedback evaluation value is counted as positive (+1) when “hot”, negative (−1) when “cold”, and 0 when “just right”. In FIG. 11, the feedback evaluation value does not exceed the feedback threshold between 9 o'clock and 9:30 and between 9:30 and 10:00. Therefore, the feedback evaluation value is set to 0 which is the initial value at 9:30 and 10:00 which are the review times. On the other hand, the feedback evaluation value exceeds the feedback evaluation threshold between 10:00 and 10:30. When the feedback evaluation threshold is exceeded, the instruction value determination unit 104 determines a new set temperature value from the first temperature control condition and the current set temperature value, and outputs a temperature control instruction including the new set temperature value to the instruction unit 105. To do. In response to the temperature control instruction, the instruction unit 105 sets the set temperature of the air conditioner 400 to a new set temperature and records it in the set temperature history value management unit 106.

  FIG. 12 is a diagram illustrating a specific example when the air conditioning control system according to the first embodiment is operated in a public place for one week. In the example shown in FIG. 12, the scene determination unit 101 determines a use scene at 9:00 every day. The determined usage scene is used until the next usage scene is determined, that is, until 9:00 on the next day. In addition, the instruction value determination unit 104 issues a reset instruction to the instruction unit 105 at 23:00 every day. Based on the reset instruction, the instruction unit 105 changes the set temperature of the air conditioner 400 to the initial set temperature. The time and day of the week when the usage scene determination and the reset instruction are performed may be arbitrarily changed by the system administrator. There may be a modified operation pattern by registering not only the day of the week but also events such as business days, regular holidays, and holidays. The setting of the use scene of the air conditioning control system and the determination time of the reset instruction may be different depending on the place where the air conditioning control system is introduced. For example, a scene determination time may be set frequently for a place where usage scene changes frequently occur such as an exhibition hall or a meeting place, or a scene determination time may be set for a place where usage scene changes such as a showroom or reception are less frequent. May be set to a small number.

  FIG. 13 is a diagram illustrating a specific example when the cooling control system according to the first embodiment is operated in an office for one day. When the cooling control system is operated in an office, scene discrimination is performed twice a day. The scene determination unit 101 determines a use scene at 9:00 and 13:30 every day. The determined usage scene is used until the next usage scene determination time. The usage scene determination method is the same as the example shown in FIG. Based on the determined usage scene, the instruction value determination unit 104 determines a feedback evaluation threshold value. Moreover, in the example of FIG. 13, 9:00 and 13:30 are also review times. Therefore, the cycle determination unit 102 determines a cycle for determining the next review time based on the number of people information received from the number of people determination unit 203 at 9:00 and 13:30. As in the example of FIG. 11, in the example of FIG. 13, the period from 9 o'clock to the next review time is all determined to be 30 minutes, with a period of 30 minutes of 9:30, 10:00,. The review time continues. The review time is again determined at 13:30, but the review time continues at 30 minute intervals thereafter. In the example of FIG. 13, the period from 17:30 to the next review time changes to 2 hours. Therefore, the review time continues in a two-hour cycle of 19:30, 21:30,. At the review time, the feedback evaluation value is set to 0 which is an initial value. The review time and the use scene determination time do not necessarily have to be the same time, but it is desirable that the period, which is the interval until the next review time, is determined again according to the update of the use scene.

  FIG. 14 is a diagram illustrating a specific example when the air conditioning control system according to the first embodiment is operated in an office for one week. In the example shown in FIG. 14, the scene determination unit 101 determines a use scene at 9:00 and 13:30 every day. However, the usage scene is determined only at 9:00 on Saturday and Sunday. The determined usage scene is used until the next usage scene is determined, that is, until 13:30 on the same day or until 9:00 on the next day. The instruction value determination unit 104 gives a reset instruction to the instruction unit 105 at 23:00 every Wednesday and Sunday. Based on the reset instruction, the instruction unit 105 changes the set temperature of the air conditioner 400 to the initial set temperature. The time and day of the week when the usage scene determination and the reset instruction are performed may be arbitrarily changed by the system administrator. There may be modified operation patterns by registering not only the day of the week but also events such as business days, regular holidays, and holidays. The setting of the use scene of the air conditioning control system and the determination time of the reset instruction may be different depending on the place where the air conditioning control system is introduced. For example, a place where the usage scene changes frequently, such as an exhibition hall or a meeting place, may be set frequently, and a place where the usage scene changes little, such as a showroom or reception, may be set low. May be.

  FIG. 15 is a flowchart showing the flow of processing when determining a usage scene according to the first embodiment. The instruction value determination unit 104 of the air conditioning control system 100 determines whether or not the current time is a time for issuing a reset instruction (step S101). When the current time is a time for performing a reset instruction (step S101: Yes), the instruction value determination unit 104 issues a reset instruction to the instruction unit 105 (step S102).

The instruction condition determination unit 103 determines the first temperature control condition based on the outdoor environment information (step S202). The instruction value determination unit 104 sets the feedback evaluation value as an initial value (step S203). The cycle determination unit 102 acquires the number of people information from the number of people determination unit 203 (step S204). The cycle determining unit 102 determines a review cycle based on the usage scene and the number of people information (step S205). Based on the determined cycle, the cycle determination unit 102 determines the next review time (step S206).

  FIG. 17 is a flowchart showing the flow of the temperature setting process for the air conditioner 400 according to the first embodiment. The instruction value determination unit 104 acquires a feedback evaluation value from the feedback unit 300 (step S301). The instruction value determination unit 104 determines whether or not the feedback evaluation value is larger than the feedback evaluation threshold and the temperature control instruction has not been executed from the previous review time to the current time (step S302). When it is larger than the feedback evaluation threshold and the temperature control instruction has not been executed from the previous review time to the current time (step S302: Yes), steps S303 to S308 are executed. If the temperature control instruction is being executed from the feedback evaluation threshold value or less or from the previous review time to the current time (step S302: No), the process proceeds to step S309.

  The instruction value determination unit 104 receives the first temperature control condition from the instruction condition determination unit 103 (step S303). The instruction value determination unit 104 receives the current set temperature value from the set temperature history value management unit 106 (step S304). The instruction value determination unit 104 adds the first temperature control condition from the current set temperature value, and determines a new set temperature value (step S305). The instruction value determination unit 104 outputs a temperature control instruction including a new set temperature value to the instruction unit 105 (step S306). The instruction unit 105 sets a set temperature in the air conditioner 400 based on the temperature control instruction (step S307). The instruction unit 105 records the temperature set in the air conditioner 400 based on the temperature control instruction in the set temperature history value management unit 106 (step S308). The air conditioning control system 100 stands by until the next operation timing (step S309).

  FIG. 18 is a flowchart showing the flow of reset instruction processing according to the first embodiment. The instruction value determination unit 104 acquires all set temperatures from the set temperature history value management unit 106 by going back a predetermined period from the current time (step S401). The instruction value determination unit 104 determines the set temperature indicated by the reset instruction based on the set temperature acquired from the set temperature history value management unit 106 (step S402).

The instruction unit 105 records the temperature set in the air conditioner 400 based on the reset instruction in the set temperature history value management unit 106 (step S405).

  In the air conditioning control system 100 configured as described above, the instruction value determination unit 104 can perform temperature control based on the feedback evaluation values collected from the occupants based on the information acquired from the BEMS 200. Therefore, it is possible to maintain and provide a temperature that follows the sensation of the occupants. For this reason, a more comfortable environment for the occupants can be provided. Furthermore, since it tends to increase energy if the temperature following the occupant is continuously provided, the instruction value determination unit 104 issues a reset instruction at a predetermined timing. An energy saving effect can be obtained by resetting the set temperature by a reset instruction.

(Modification)
FIG. 19 is a diagram illustrating a first modification of an image displayed on the feedback unit 300 according to the first embodiment. The feedback unit 300 according to the first embodiment accepts three types of opinions “hot”, “just right”, or “cold” and three patterns of icons divided into three colors of red, green, and blue. It is defined that the feedback evaluation value corresponds to each of the three types of patterns. The area 500a is a specific example of an image displayed from the feedback unit 300 to the user. The user can input an opinion by selecting the icons of the areas 501a to 503a included in the area 500a. For example, when the icon of the area 501a is selected, an opinion of “hot” is input, and the feedback evaluation value is added as “+1”. When the icon in the area 502a is selected, an opinion of “just right” is input, and the feedback evaluation value is added as “0”. When the icon in the region 503a is selected, an opinion of “cold” is input, and the feedback evaluation value is added as “−1”. The feedback evaluation value corresponding to the opinion of the occupant may be configured so that the system administrator can arbitrarily change it. By being configured in this way, it is possible to accept opinions from users who cannot recognize characters or who cannot read displayed characters. When each area is selected once, the specific amount to be added is defined by a numerical value and added by a plus or minus report. In addition, if only the amount of addition when each area is selected once, the total number of opinions received that select all areas is separately counted so that the effect of “0” does not fade, and the result of the addition is expressed as an opinion. A value leveled by the total number of receptions may be defined as a feedback evaluation value.

  FIG. 20 is a diagram illustrating a second modification of the image displayed on the feedback unit 300 according to the first embodiment. The region 500b is a specific example of an image displayed to the user from the feedback unit 300. An area 504 is an input unit that receives a user's opinion. The region 504 includes a triangular designation portion and a line through which the designation portion can be moved. A region 505 is a meter representing an opinion on the room temperature. The region 505 includes regions 501b, 502b, and 503b that express opinions about room temperature. The region 501b is a region representing “hot”. The area 502b is an area representing “just right”. The region 503b is a region representing “cold”. An area 506 is an icon for the feedback unit 300 to send an opinion to the instruction value determination unit 104. The user moves the instruction unit to a desired place by operating the instruction unit of the area 504 along the line. For example, when the user wants to input “hot” as an opinion, the user moves the instruction unit to a location adjacent to the region 501b. The user moves the instruction unit to a desired place and operates the area 506. When the area 506 is operated, the feedback unit 300 transmits a feedback evaluation value to the instruction value determination unit 104. Note that the “hot” feedback evaluation value may vary depending on the location of the region 501b. For example, when the instruction unit of the area 504 is moved to the upper part of the area 501b, “+3” is input as the feedback evaluation value. On the other hand, when the instruction part of the area 504 is moved to the lower part of the area 501b, “+1” is input as the feedback evaluation value. Alternatively, the evaluation values may not be divided into levels within the same area.

  The feedback evaluation value for the accepted input may be different depending on the human attribute. For example, a case where the gender of a person is known will be described. In the case of males, when a hot opinion is input, a feedback evaluation value is “1”, and when an “just good” opinion is input, a feedback evaluation value is “0” and a “cold” opinion is input. Then, the feedback evaluation value may be input as “−1”. In the case of females, when an opinion of “hot” is input, a feedback evaluation value is “2”, and when an opinion of “just right” is input, an opinion of “0” and “cold” is input as a feedback evaluation value Then, the feedback evaluation value may be input as “−2”. The attribute may be information other than gender. For example, a case where a user is classified into two types of attributes, that is, a general user or a premium member will be described. For general members, when a “hot” opinion is input, the feedback evaluation value is “1”, and when an “just good” opinion is input, the feedback evaluation value is “0”, “cold” opinion When input, the feedback evaluation value may be input as “−1”. In the case of premium members, if an opinion of “hot” is input, the feedback evaluation value is “2”, and if an opinion of “just right” is input, the feedback evaluation value is “0” and an opinion of “cold” When input, the feedback evaluation value may be input as “−2”.

  The feedback evaluation value corresponding to the opinion of the occupant may be configured so that the system administrator can arbitrarily change it. The instruction value determination unit 104 may determine whether or not the feedback threshold is exceeded by using a ratio between the physical quantity and the number of inputs. For example, a case where the feedback evaluation value of “hot” is “Xi”, the feedback evaluation value of “just good” is “Yj”, and the feedback evaluation value of “cold” is “Zk” will be described. “I, j, k” represents index numbers of feedback evaluation values of “hot”, “just right”, and “cold”, respectively. The “hot” feedback count is Nh. The count of “just good” feedback is Nm. The count number of “cold” feedback is Nc. The total value using these is calculated | required based on the following Formula (1). Formula (1) is a mathematical expression that represents an example of a formula for calculating the feedback evaluation value.

  In equation (1), the denominators Nh, Nm, and Nc are the sums of the “hot”, “just right”, and “cold” indexes, and are the counts of the feedback evaluation values. In the formula (1), each term of the numerator takes the total of each feedback evaluation value itself.

  The feedback evaluation threshold is determined based on the total value. Further, when the feedback evaluation values of “hot” and “cold” are weighted, the weight is also included in the count number.

  The instruction value determination unit 104 may determine whether or not the feedback evaluation threshold is exceeded based on the ratio A of various count numbers. For example, in the case of “hot”, if Nh / Nm> A, the instruction value determination unit 104 outputs a temperature control instruction. In the case of “cold”, if Nc / Nm> A, the instruction value determination unit 104 outputs a temperature control instruction. In this case, it is preferable to provide an initial value for Nm. For example, the initial value may be 3 times. The ratio A and the initial value may be configured so that the system administrator can arbitrarily change them.

  The instruction value determination unit 104 may determine whether or not the feedback evaluation threshold is exceeded based on the number of counts. For example, in the case of “hot”, when the number of Nh exceeds a predetermined number and is equal to or exceeds the sum of the numbers of Nm and Nc, the instruction value determination unit 104 may output a temperature control instruction. Good. It should be noted that the predetermined number of times may be configured so that the system administrator can arbitrarily change it.

(Second Embodiment)
Next, an air conditioning control system 100a in the second embodiment will be described. Hereinafter, differences from the first embodiment will be described.

  FIG. 21 is a functional block diagram illustrating the overall configuration of the air conditioning control system 100a of the second embodiment. The air conditioning control system 100a is different from the first embodiment in that it includes a feedback determination unit 107, but the other configuration is the same as the air conditioning control system 100 in the first embodiment. The feedback evaluation threshold in the first embodiment is hereinafter referred to as “first threshold”.

  The feedback determination unit 107 outputs a set temperature instruction to the instruction value determination unit 104 when the feedback evaluation value exceeds the second threshold value a predetermined number of times and the temperature control instruction has not been executed from the previous review time to the current time. To communicate. The instruction value determination unit 104 receives the second temperature control condition from the instruction condition determination unit 103. Similar to the first temperature control condition, the second temperature control condition defines a specific code symbol and a numerical value related to the direction and width in which the set temperature of the air conditioner 400 is changed. The second threshold value may be any value as long as it is a value between the initial value of the feedback evaluation value and the first threshold value. For example, the second threshold value may be half of the first threshold value. That is, after the first threshold value is determined by the instruction value determination unit 104, one half of the value may be set as the second threshold value. The predetermined number of times may be any number as long as the feedback determination unit 107 can count. The predetermined number of times is, for example, three times. The second threshold value and the predetermined number of times may be configured to be arbitrarily changed by the system administrator. When the air conditioner 400 has a plurality of air conditioning control areas, the second threshold value may be determined for each air conditioning control area. The second temperature control condition is an aspect of the temperature control condition.

  The feedback determination unit 107 determines whether or not the feedback evaluation value exceeds the second threshold value. When the feedback evaluation value exceeds the second threshold value, the feedback determination unit 107 counts the excess number. When the excess number exceeds the predetermined number and the temperature control instruction has not been executed from the previous review time to the current time, the feedback determination unit 107 notifies the instruction value determination unit 104 to output the set temperature instruction. To do. The instruction value determination unit 104 determines a new set temperature value based on the current set temperature acquired from the set temperature history value management unit 106 and the second temperature control condition received from the instruction condition determination unit 103. A temperature control instruction including a preset temperature value is output to the instruction unit 105. Specifically, the instruction value determination unit 104 adds the second temperature control condition received from the instruction condition determination unit 103 to the current set temperature value acquired from the set temperature history value management unit 106 as the new set temperature value. Decide by. Between the first review time and the next review time, the second or first temperature control condition can be output only once each or together. When the feedback determination unit 107 outputs the first temperature control condition to the instruction value determination unit 104, the feedback determination unit 107 sets the number of times the second threshold is exceeded to zero.

  FIG. 22 is a diagram illustrating a specific example of the second temperature control condition according to the second embodiment. The second temperature control condition may be a value different from the first temperature control condition determined by the instruction condition determination unit 103, or a condition that is more relaxed than the first temperature control condition. For example, when the outside air temperature is 30 ° C. or more and the amount of solar radiation is 2 MJ / m 2 or more, the instruction condition determination unit 103 outputs control for lowering the set temperature of the air conditioner 400 by 1 ° C. to the instruction value determination unit 104. Similarly, when the outside air temperature is 30 ° C. or higher and the amount of solar radiation is less than 2 MJ / m 2, the instruction condition determination unit 103 outputs control for lowering the set temperature of the air conditioner 400 by 0.5 ° C. to the instruction value determination unit 104. To do. It is desirable that the temperature control condition is defined in each of the cooling control and the heating control. Moreover, you may each define by the place of an air-conditioning control area. Specific numerical values of the temperature control conditions may be configured so that the system administrator can arbitrarily change them. When defined for each air conditioning control area, the air conditioning control area with many windows and the control area adjacent to the entrance / exit are easily affected by outdoor environment information, and the control area away from the entrance / exit without windows. The temperature can be managed by absorbing the difference of each air-conditioning control area that is not easily affected by the outdoor environment information. Similar to the second temperature control condition, the second temperature control condition is determined based on the outdoor environment information acquired from the outdoor environment detection unit 204 at each review time.

  In the case where the first threshold value is exceeded after the number of times of exceeding the second threshold exceeds the predetermined number of times between two successive review times, the indication value determining unit 104 determines that the number of times of exceeding the second threshold is the predetermined number of times. The temperature including the new set temperature by adding the difference value between the temperature control instruction condition when the temperature exceeds the first threshold and the temperature control instruction condition when the first threshold is exceeded to the current set temperature acquired from the set temperature history value management unit 106 Output to the instruction unit 105 as a control instruction.

  FIG. 23 is a diagram illustrating a specific example when the cooling control system according to the second embodiment is operated in an office. In the cooling control system, the feedback evaluation value is added as a positive direction when “hot”, a negative direction when “cold”, and 0 when “just right”. In FIG. 23, the predetermined number of times required for the feedback determination unit 107 to output the second temperature control condition is three.

  In FIG. 23, the scene determination unit 101 determines a use scene at 9:00 am. The instruction value determination unit 104 determines the first threshold value and the second threshold value based on the determined usage scene. In the example of FIG. 23, 9 am is also the review time. Therefore, the cycle determination unit 102 determines a cycle for determining the next review time based on the number of people information received from the number of people determination unit 203. As in the example of FIG. 11, in the example of FIG. 23, the period from 9 o'clock to the next review time is all determined to be 30 minutes, and the period of 9:30, 10 o'clock,. The review time continues. At the review time, the feedback evaluation value is set to 0, which is an initial value. The review time and the use scene determination time do not necessarily have to be the same time, but it is desirable that the period, which is the interval until the next review time, is determined again according to the update of the use scene.

  In FIG. 23, the feedback evaluation value exceeds the second threshold between 9:30 and 10:00, but does not exceed the first threshold. Therefore, the feedback determination unit 107 has an excess count of 1 between 9:30 and 10:00. Similarly, when the review time is between 10 o'clock and 10:30 and between 11 o'clock and 11:30, the feedback evaluation value exceeds the second threshold but does not exceed the first threshold, respectively. It has occurred. Therefore, the number of times of excess is 3 at 11:30.

  In FIG. 23, the feedback evaluation value exceeds the second threshold but does not exceed the first threshold during the review time from 14:00 to 14:30. Therefore, the number of times of excess counted by this time of excess is 4, and the number of times of excess is greater than a predetermined number. The feedback determination unit 107 outputs the second temperature control condition to the instruction value determination unit 104. The instruction value determination unit 104 determines a new set temperature value from the received second temperature control condition and the current set temperature value, and outputs a temperature control instruction including the new set temperature value to the instruction unit 105. In response to the temperature control instruction, the instruction unit 105 sets the set temperature of the air conditioner 400 to a new set temperature and records it in the set temperature history value management unit 106.

  FIG. 24 is a flowchart showing the flow of temperature setting processing to the air conditioner 400 of the second embodiment. The other processing flow is the same as that described in the first embodiment, A in FIG. 24 comes from A in FIG. 15, and B in FIG. 24 continues to B in FIG. The instruction value determination unit 104 acquires a feedback evaluation value from the feedback unit 300 (step S501). The instruction value determination unit 104 determines whether or not the feedback evaluation value is greater than the first threshold value and the temperature control instruction has not been executed from the previous review time to the current time (step S502). If it is greater than the first threshold and the temperature control instruction has not been executed from the previous review time to the current time (step S502: Yes), the process proceeds to step S507. If the temperature control instruction is being executed from the first threshold value or below or from the previous review time to the current time (step S502: No), the process proceeds to step S503.

  The feedback determination unit 107 of the air conditioning control system 100a determines whether or not the feedback evaluation value is greater than the second threshold value (step S503). When the feedback evaluation value is not larger than the second threshold value (step S503: No), the process proceeds to step S512. When the feedback evaluation value is greater than the second threshold (step S503: Yes), the feedback determination unit 107 counts the number of times the second threshold is exceeded (step S504). The feedback determination unit 107 determines whether or not the number of times the second threshold is exceeded is greater than a predetermined number and whether or not a temperature control instruction has been executed from the previous review time to the current time (step S505). When the number of times the second threshold is exceeded is equal to or less than the predetermined number, or when the temperature control instruction is executed from the previous review time to the current time (step S505: No), the process proceeds to step S512. When the number of times the second threshold is exceeded is greater than the predetermined number and the temperature control instruction has not been executed from the previous review time to the current time (step S505: Yes), the feedback determination unit 107 sets the number of times the second threshold is exceeded. It is set to 0 (step S506).

  When the feedback evaluation value is larger than the first threshold and the temperature control instruction has not been executed from the previous review time to the current time (step S502: Yes), or the feedback evaluation value is the second threshold If the temperature control instruction is not executed from the previous review time to the current time (step S505: Yes), the first temperature control condition or the second temperature control condition is received from the instruction condition determination unit 103 (step S505). S507). The instruction value determination unit 104 adds the first temperature control condition or the second control temperature condition from the current set temperature value, and determines a new set temperature value (step S508). The instruction value determination unit 104 outputs a temperature control instruction including a new set temperature value to the instruction unit 105 (step S509). The instruction unit 105 sets the set temperature of the air conditioner 400 based on the temperature control instruction (step S510). The instruction unit 105 records the temperature set in the air conditioner 400 based on the temperature control instruction in the set temperature history value management unit 106 (step S511). The air conditioning control system 100 stands by until the next program operation timing (step S512).

(Modification)
If the number of times the second threshold is exceeded exceeds the predetermined number and the case where the first threshold is exceeded at the same time between two successive review times, the instruction unit 105 determines that the first threshold is exceeded. The temperature control instruction may be ignored. Alternatively, the instruction value determination unit 104 manages the difference value between the temperature control instruction condition when the second threshold value exceeds the predetermined number and the temperature control instruction condition when the first threshold value exceeds the set temperature history value management. The current set temperature acquired from the unit 106 may be added to the instruction unit 105 as a temperature control instruction including a new set temperature.

  When the number of times the second threshold is exceeded exceeds the predetermined number and the case where the first threshold is exceeded simultaneously between two successive review times, the instruction value determination unit 104 sets the first threshold to It may be changed. Specifically, the instruction value determination unit 104 may bring the value of the first threshold to the initial value of the feedback evaluation value so that the first threshold is close to the second threshold. The gathering value may be configured so that the system administrator can arbitrarily change it.

(Modification)
The second threshold excess count counted by the feedback determination unit 107 may be set to 0 at an appropriate timing. For example, it may be when a new scene is determined by the scene determination unit 101, or when the date read from the apparatus on which the program is executed changes. The timing at which the number of times the second threshold value is exceeded may be configured so that the system administrator can arbitrarily change the timing.

  In the air-conditioning control system 100a configured as described above, the feedback determination unit 107 sets the second threshold value, so that there is a setting error of the first threshold value compared to the first embodiment, and feedback is performed many times. However, it can relieve physical and psychological discomfort for those who cannot feel improvement. Therefore, it is possible to provide a comfortable environment for more people in the room.

  In the above embodiments, the scene determination unit 101, the cycle determination unit 102, the instruction condition determination unit 103, the instruction value determination unit 104, and the instruction unit 105 are assumed to be software function units. There may be.

  According to at least one embodiment described above, by having the instruction value determination unit 104, the feedback evaluation values collected from the occupants are reflected in the air conditioner 400, thereby providing a more comfortable environment for the occupants. Can be provided.
