Detailed Description
The present invention will be described in further detail with reference to the following embodiments and the accompanying drawings, in order to make the objects, technical solutions and advantages of the present invention more apparent. The exemplary embodiments of the present invention and the descriptions thereof are used herein to explain the present invention, but are not intended to limit the invention.
Considering that the existing emergency control method under the fault condition of the air conditioning unit mostly does not specifically distinguish the fault of the non-refrigeration equipment and the fault of the refrigeration equipment in the air conditioning unit, the situation that the air conditioning unit only has the fault of the non-refrigeration equipment often occurs, and the corresponding emergency control, such as refrigeration or ventilation, of the air conditioning unit cannot be effectively performed by utilizing the refrigeration equipment without the fault, so that the user experience is poor. That is, the conventional method is often implemented under the condition of failure of non-refrigeration equipment, and the technical problem that effective emergency control cannot be performed on the air conditioning unit is often existed. Aiming at the root cause of the technical problem, the method and the device consider that the fault of the air conditioning unit can be specifically analyzed through one device, when the condition that the air conditioning unit only has the fault of non-refrigeration equipment is determined, the corresponding emergency control is carried out on the air conditioning unit by effectively utilizing the refrigeration equipment without the fault, so that the technical problem that the effective emergency control cannot be carried out on the air conditioning unit under the condition that the fault of the non-refrigeration equipment exists in the existing method can be solved, and the technical effect that the corresponding emergency control can be carried out on the air conditioning unit by effectively utilizing the refrigeration equipment under the condition that the fault of the non-refrigeration equipment and the normal refrigeration equipment exist can be achieved, so that the user experience degree is improved.
Based on the thinking thought, the embodiment of the application provides an emergency control device of an air conditioning unit. Specifically, reference may be made to a schematic structural diagram of an emergency control device of an air conditioning unit according to an embodiment of the present invention shown in fig. 1. The control system of the air conditioner temperature specifically can comprise: a first detector 101, a first switch 102, a second switch 103, a third switch 104. The above-described respective structures can be specifically described by the following.
The first detector 101 may be specifically connected to an inner machine main control board, an outer machine main control board, and a line controller of an air conditioning unit, and may be specifically used to detect whether the inner machine main control board, the outer machine main control board, and the line controller have a fault;
the first switch 102 may be specifically connected to the first detector 101, the second switch 103, and the third switch 104, and may be specifically configured to perform emergency control on the air conditioning unit through the second switch 103 or the third switch 104 when at least one of the internal machine main control board, the external machine main control board, and the line controller fails;
wherein, the second switch 103 may be specifically connected to an inner fan driving board of the air conditioning unit; the third switch 104 may be specifically connected to an outer fan driving plate, a compressor driving plate, and an inner fan driving plate of the air conditioning unit. In this way, the second switch 103 can be controlled to control the power supply of the inner fan driving plate of the air conditioning unit, so that the starting and running of the inner fan can be controlled; the third switch 104 can be controlled to control the power supply of the outer fan driving plate, the compressor driving plate and the inner fan driving plate of the air conditioning unit, so that the starting and running of the outer fan, the inner fan and the compressor can be controlled.
In this embodiment, it should be noted that the inner machine main control board, the outer machine main control board, and the line controller of the air conditioning unit are generally used for communication and control in operation of the air conditioning unit, and are not directly used for refrigeration or ventilation. Therefore, in the case of one or more faults in an inner machine main control board, an outer machine main control board and a wire controller of the air conditioning unit, the normal operation of refrigeration equipment in the air conditioning unit, such as a compressor, an outer fan and an inner fan, is not affected. Therefore, the faults of the inner machine main control board, the outer machine main control board and the wire controller can be regarded as the faults of non-refrigeration equipment.
In this embodiment, the first switch 102 may be a rotary switch. During specific operation, the corresponding rotation gear can be selected by rotating the knob switch, and specific operation control is performed according to the mode corresponding to the rotation gear. In this way, the first switch 102 may flexibly select a more appropriate mode to perform corresponding emergency control on the air conditioning unit when the air conditioning fails according to a specific failure condition.
In this embodiment, the first switch 102 may specifically be provided with three rotation gears, and the three rotation gears respectively correspond to the following three modes: an automatic mode, a preset cooling mode, a preset ventilation mode. The automatic mode can specifically be to automatically control the operation of the air conditioning unit according to a control instruction received or generated by an inner machine main control board, an outer machine main control board or a wire controller of the air conditioning unit under the condition that the air conditioning unit works normally. And under the condition that the air conditioning unit works normally and has no fault, the air conditioning unit can be automatically controlled by rotating and maintaining the first switch 102 at the rotating gear corresponding to the automatic mode so as to receive or generate control instructions according to the main control board of the internal machine, the main control board of the external machine or the line controller. The preset cooling mode may be a non-automatic cooling mode different from the automatic mode. Specifically, the preset refrigeration mode may be a manual refrigeration mode or a refrigeration mode for performing refrigeration according to a preset rule, that is, a mode for performing refrigeration control without receiving or generating a control instruction according to an inner machine main control board, an outer machine main control board or a line controller of the air conditioning unit. In addition, when the air conditioning unit fails, according to specific failure conditions and construction requirements, the first switch 102 is rotated to a rotation gear position corresponding to a preset refrigeration mode, so as to perform corresponding non-automatic refrigeration control on the air conditioning unit according to the preset refrigeration mode. The preset ventilation mode may be a non-automatic ventilation mode different from the automatic mode. Specifically, the preset ventilation mode may be a manual ventilation mode or a ventilation mode for ventilation according to a preset rule, that is, a mode for ventilation control without receiving or generating a control instruction according to an inner main control board, an outer main control board or a line controller of the air conditioning unit. In addition, when the air conditioning unit fails, according to specific failure conditions and construction requirements, the first switch 102 is rotated to a rotation gear position corresponding to a preset ventilation mode, so as to perform corresponding non-automatic ventilation control on the air conditioning unit according to the preset ventilation mode.
In this embodiment, in order to implement the above-mentioned preset ventilation mode, when the rotation gear of the first switch 102 is the preset ventilation mode, in a specific implementation, the second switch 103 may be controlled to be turned on by rotating the first switch 102 to the rotation gear corresponding to the preset ventilation mode, so as to supply power to an inner fan driving board in the air conditioning unit, so as to ventilate an area where the air conditioning unit is located, so that the air conditioning unit may be controlled in an emergency manner according to the preset ventilation mode by using a driving machine without failure in the air conditioning unit without passing through an inner machine main control board, an outer machine main control board or a line controller of the air conditioning unit.
In this embodiment, in order to realize the preset cooling mode, when the rotation gear of the first switch 102 is in the preset cooling mode, in a specific implementation, the third switch 104 may be controlled to be turned on by rotating the first switch 102 to the rotation gear corresponding to the preset cooling mode, so that the outer fan driving plate, the compressor driving plate, and the inner fan driving plate may be powered to cool an area where the air conditioning unit is located, so that the air conditioning unit may be controlled in an emergency manner according to a preset ventilation mode by using a driving machine, an outer fan, and an inner fan of the air conditioning unit without passing through an inner machine main control plate, an outer machine main control plate, or a line controller of the air conditioning unit.
In this embodiment, in order to protect the air conditioning unit, avoid damaging the content structure of the air conditioning unit, and simultaneously, also in order to ensure the safety of subsequent maintenance personnel, the device may specifically further include a second detector, where the second detector may specifically be connected to an exhaust device and an air suction device of the air conditioning unit, and may specifically be used to detect whether the exhaust pressure and the air suction pressure of the air conditioning unit meet preset requirements. The exhaust pressure and the suction pressure of the air conditioning unit meet preset requirements, specifically, the exhaust pressure of the air conditioning unit is smaller than an exhaust pressure threshold value, and the suction pressure of the air conditioning unit is smaller than a suction pressure threshold value. Thus, the operation of the refrigeration equipment of the air conditioning unit can be continued. The refrigerating equipment of the air conditioning unit can specifically comprise a compressor, an inner fan, an outer fan and the like of the air conditioning unit.
In a specific embodiment, the first detector 101 may detect the inner machine main control board, the outer machine main control board, and the line controller of the air conditioner unit in real time, so as to determine whether the inner machine main control board, the outer machine main control board, and the line controller of the air conditioner unit have faults. Under the condition that one or more of an inner machine main control board, an outer machine main control board and a wire controller of the air conditioning unit are determined to be faulty and refrigerating equipment is not faulty, the air conditioning unit can be determined to be faulty only for non-refrigerating equipment, and the refrigerating equipment of the air conditioning unit can still work continuously. During the period of waiting for repair by maintenance personnel, the refrigeration equipment can be effectively utilized to continue working so as to improve the experience of users. Specifically, the first switch 102 may be rotated to a rotation gear corresponding to a preset ventilation mode according to a user's requirement and a specific environmental condition, so that the second switch 103 may be controlled to be turned on, so as to supply power to an inner fan driving board in the air conditioning unit, so as to ventilate an area where the air conditioning unit is located by controlling an inner fan. The second switch 102 may be rotated to a rotation gear corresponding to a preset cooling mode, so that the third switch 104 may be controlled to be turned on, so as to supply power to the outer fan driving plate, the compressor driving plate, and the inner fan driving plate in the air conditioning unit, so as to cool an area where the air conditioning unit is located by controlling cooperation of the outer fan, the inner fan of the compressor, and the like.
In this embodiment, the area where the air conditioning unit is located may be a target area for cooling of the air conditioning unit, for example, a large commercial center, or an area such as a cabin or a cabin.
In the embodiment of the application, the specific fault condition of the air conditioning unit is determined through the first detector, the corresponding refrigeration equipment is controlled through the second switch or the third switch under the condition of the fault of the non-refrigeration equipment of the air conditioning unit through the first switch, so that the corresponding emergency control is carried out on the air conditioning unit, the technical problem that the effective emergency control cannot be carried out on the air conditioning unit under the condition of the fault of the non-refrigeration equipment in the existing method is solved, and the technical effect that the corresponding emergency control can be carried out on the air conditioning unit by effectively utilizing the refrigeration equipment under the condition that the fault of the non-refrigeration equipment is normal is achieved, so that the user experience degree is improved is achieved.
In one embodiment, the first switch may be a rotary switch. In this way, in the implementation, the first switch may be rotated to a corresponding rotation gear, so that the operation of the air conditioning unit may be controlled according to the mode corresponding to the rotation gear.
In one embodiment, the first switch may be provided with three rotational gears, which correspond to three different control modes, respectively: an automatic mode, a preset cooling mode, a preset ventilation mode. Of course, the above three modes are only for the purpose of more clearly describing the embodiments of the present application, and other possible control modes may be added as one of the control modes according to the specific situation and the construction requirement.
In one embodiment, the air conditioning unit is operated in a predetermined ventilation mode in order to be able to be controlled more accurately. When the method is implemented, under the condition that the rotation gear of the first switch is in a preset ventilation mode, the second switch can be controlled to be turned on through the first switch to supply power for the inner fan driving plate so as to ventilate an area where the air conditioning unit is located.
In one embodiment, the air conditioning unit is operated in a preset cooling mode in order to be able to be controlled more accurately. The method comprises the steps that when the rotation gear of the first switch is in a preset refrigeration mode, the first switch is used for controlling the third switch to be turned on, and the power is supplied to the outer fan driving plate, the compressor driving plate and the inner fan driving plate, so that the area where the air conditioning unit is located is refrigerated.
In one embodiment, in order to protect the air conditioning unit, damage to the content structure of the air conditioning unit is avoided, and meanwhile, in order to ensure the safety of subsequent maintenance personnel, the device specifically may further include a second detector, where the second detector specifically may be connected to an exhaust device and an air suction device of the air conditioning unit, and specifically may be used to detect whether the exhaust pressure and the air suction pressure of the air conditioning unit meet preset requirements. The exhaust pressure and the suction pressure of the air conditioning unit meet preset requirements, specifically, the exhaust pressure of the air conditioning unit is smaller than an exhaust pressure threshold value, and the suction pressure of the air conditioning unit is smaller than a suction pressure threshold value. Thus, the operation of the refrigeration equipment of the air conditioning unit can be continued. The refrigerating equipment of the air conditioning unit can specifically comprise a compressor, an inner fan, an outer fan and the like of the air conditioning unit.
In one embodiment, in order to ensure that the air conditioning unit is emergency protected when it is determined that the exhaust pressure and the suction pressure of the air conditioning unit do not meet the preset requirements, the first switch may be specifically connected to the second detection device, and may be specifically used to disconnect the third switch when the exhaust pressure and/or the suction pressure of the air conditioning unit do not meet the preset requirements. The exhaust pressure and/or the air suction pressure of the air conditioning unit do not meet the preset requirements, specifically, the exhaust pressure of the air conditioning unit is greater than or equal to an exhaust pressure threshold, or the air suction pressure is greater than or equal to an air suction pressure threshold, and the exhaust pressure is greater than or equal to the exhaust pressure threshold and the air suction pressure is greater than or equal to the air suction pressure threshold. Under the condition, the operation of the air conditioning unit can be considered to have potential safety hazards, the operation of a compressor, an external fan and an internal fan in the air conditioning unit can be interrupted by switching off the third switch through the first switch, and the air conditioning unit can be stopped in time to work according to a preset refrigeration mode.
In one embodiment, when it is determined that the exhaust pressure and the suction pressure of the air conditioning unit do not meet the preset requirements, in order to timely inform staff, the air conditioning device is prevented from being directly started, and the device specifically can further comprise an alarm device. The alarm device may be specifically connected to the second detector, and may be specifically configured to issue an alarm when the discharge pressure and/or the suction pressure of the air conditioning unit do not meet a preset requirement.
In one embodiment, in order to timely alarm, the alarm device reminds a worker, and the alarm device specifically may include an alarm lamp. For example, the alarm lamp can be connected with the second detector, so that a red light can be lightened when the exhaust pressure and the suction pressure of the air conditioning unit do not meet the preset requirements, and the air conditioning unit can be warned to workers that potential safety hazards exist and can be stopped in time. The alarm device may also comprise a buzzer. For example, the buzzer may be connected to the second detector, so that an alarm may be given when the exhaust pressure and the suction pressure of the air conditioning unit do not meet the preset requirements, so as to alert the staff that the air conditioning unit has a potential safety hazard, and the operation should be stopped in time. The alarm device may further comprise an alarm information transmitter. For example, the alarm information transmitter is connected to the second detector and has an information transmitting function. Therefore, when the exhaust pressure and the suction pressure of the air conditioning unit do not meet the preset requirements, an alarm short message can be sent to a mobile phone of a worker so as to warn the worker that the air conditioning unit has potential safety hazards and the operation should be stopped in time; and requires timely service personnel to request on-site repair.
Compared with the prior art, the emergency control device for the air conditioning unit provided by the embodiment of the invention determines the specific fault condition of the air conditioning unit through the first detector, and controls the corresponding refrigeration equipment through the second switch or the third switch under the condition that the non-refrigeration equipment of the air conditioning unit is in fault, so as to perform corresponding emergency control on the air conditioning unit, thereby solving the technical problem that the prior art cannot perform effective emergency control on the air conditioning unit under the condition that the non-refrigeration equipment is in fault, and achieving the technical effect that the refrigeration equipment can be effectively used for performing corresponding emergency control on the air conditioning unit under the condition that the non-refrigeration equipment is in fault and the refrigeration equipment is normal, and improving the user experience; the first switch is designed as a knob switch, and the rotation gears corresponding to the knob switch are respectively set as follows: the automatic mode, the preset refrigeration mode and the preset ventilation mode, so that the technical effects of flexibly performing emergency control by selecting a corresponding proper mode according to specific conditions can be achieved; and the second detector is used for detecting whether the exhaust pressure and the suction pressure of the air conditioning unit meet preset requirements or not, and stopping entering a preset refrigeration mode under the condition that the preset requirements are not met, so that the air conditioning unit can be protected in time, and the safety coefficient is improved.
Based on the same inventive concept, the embodiment of the invention also provides a method for performing emergency control of the air conditioning unit by using the emergency control device of the air conditioning unit. Because the principle of solving the problem of the emergency control method of the air conditioning unit is similar to that of the emergency control device of the air conditioning unit, the implementation of the emergency control method of the air conditioning unit can be referred to the implementation of the emergency control device of the air conditioning unit, and the repeated parts are not repeated.

In a specific scene example, the emergency control device and the emergency control method of the air conditioning unit provided by the application are used for carrying out corresponding emergency treatment on the central air conditioner of a hotel. Specifically, referring to fig. 3, a schematic diagram of emergency control of an air conditioning unit by using the emergency control device of the air conditioning unit according to the embodiment of the present invention in one scenario example is implemented as follows.
In a case where the air conditioning unit is operating normally, referring to fig. 4, a schematic diagram of an operation panel where the first switch in the emergency control device of the air conditioning unit according to the embodiment of the present invention is located is shown, where the manual knob switch (i.e., the first switch) is located in an "automatic" (i.e., an automatic mode) position on the operation panel. After the main power switch is turned on, and the button switch at the 'automatic' position is turned on, the air conditioning unit can operate (namely, automatically control) according to the instruction of the main control board. Referring to fig. 3, as shown by analyzing a specific electrical schematic diagram, the S1 main power switch is turned on, the automatic mode of the knob switch SB1 (i.e., the first switch) is turned on, and the button switch S2 is simultaneously in an on state, at this time, the inner machine main control board AP1 and the outer machine main control board AP2 are both in an on state, and the unit can control the ventilation, cooling and heating instructions of the unit to operate through the line controller. The above is the specific situation that the air conditioning unit automatically operates in a normal working state without faults.
When the main control board AP1 of the internal machine or the main control board AP2 of the external machine or the line controller fails (i.e. the first detector detects that at least one of the three fails), the knob switch SB1 may be adjusted to a manual ventilation mode (i.e. a preset ventilation mode), and the control button switch S4 (i.e. the second switch) is turned on, so that the driving board AP4 of the internal fan is powered on, and further, the internal fan may be turned on to operate, so as to implement an indoor ventilation mode (i.e. control the air conditioning unit to operate according to the preset ventilation mode).
When the main control board AP1 of the internal machine or the main control board AP2 of the external machine or the line controller fails, the knob switch SB1 may be adjusted to a manual cooling mode (i.e., a preset cooling mode), and the main power switch S1 is turned on, while the button switch S3 (i.e., the third switch) is turned on. And when the low-voltage switch and the high-voltage switch are normal, the compressor driving plate AP3, the inner fan driving plate AP4 and the outer fan driving plate AP5 are controlled to be powered on, and further, the compressor, the inner fan and the outer fan can be started to operate, so that a manual refrigeration function is realized (namely, an air conditioning unit is controlled to operate according to a preset refrigeration mode).
The discharge pressure or the suction pressure may be detected in real time using the second detector while the knob switch SB1 is adjusted to the manual ventilation mode or the manual cooling mode. When the exhaust pressure or the suction pressure of the unit is abnormal, the high-voltage switch or the low-voltage switch is disconnected, at the moment, potential safety hazards exist, the button switch S3 can be disconnected through the knob switch SB1, so that the manual refrigerating circuit is disconnected, and then the inner fan, the outer fan and the compressor are stopped (namely, the preset refrigerating mode is stopped). Simultaneously, the opening of fault alarm lamp and bee calling organ is triggered, sends the warning in order to indicate that staff air conditioning unit breaks down, has the potential safety hazard, needs the outage to seek the reason. At this time, the air conditioning unit is also provided with an S1 main power switch, and the S1 can be disconnected, so that the whole loop of the air conditioning unit is in a power-off state for subsequent overhaul and debugging.
In this embodiment, referring to fig. 4, the push-button switches S2, S3, S4 may be used to prevent the user from directly rotating the knob switch without turning off the main power switch S1, which results in potential safety hazard of voltage impact in the gear shifting process, and also provides a second confirmation opportunity for the staff.
