For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
In the description of the present specification, a description referring to terms "one embodiment," "some embodiments," "examples," "specific examples," or "some examples," etc., means that a particular feature, structure, material, or characteristic described in connection with the embodiment or example is included in at least one embodiment or example of the embodiments of the present invention.

Furthermore, the particular features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples. Furthermore, the different embodiments or examples described in this specification and the features of the different embodiments or examples may be combined and combined by those skilled in the art without contradiction.
The control method, the control device and the air conditioner of the solar air conditioner are described below with reference to the accompanying drawings. Before the embodiments of the present invention are described in detail, the entire application scenario is described. The control method, the control device, the electronic equipment and the computer readable storage medium of the solar air conditioner can be applied to the local solar air conditioner, cloud platforms in the field of the Internet, cloud platforms in the field of other kinds of Internet, or third party equipment. The third party device may include a mobile phone, a tablet computer, a notebook computer, a vehicle-mounted computer, and other intelligent terminals.
In the following, a control method suitable for a solar air conditioner is only described as an example, and it should be understood that the control method according to the embodiment of the present invention may also be suitable for a cloud platform and a third party device.
As shown in fig. 1, a control method of a solar air conditioner according to an embodiment of a first aspect of the present invention includes:
Step S1, receiving a signal for executing a sleep function, and controlling a solar air conditioner to execute the sleep function;
In step S1, when the user sets the sleep mode through the remote controller or the control panel on the air conditioner, the air conditioner receives this signal. This signal triggers the start of the sleep function and the air conditioner starts to enter the energy saving mode.
Among other things, sleep mode generally means that the air conditioner will adjust its operating parameters to provide a more comfortable environment during the user's sleep while reducing energy consumption.
Step S2, under the sleeping function, after the solar air conditioner is determined to continuously run for a first set period of time at the initial air outlet temperature, fine adjustment is carried out on the air outlet temperature of the solar air conditioner according to the current working mode of the solar air conditioner;
in step S2, in the sleep mode, the air conditioner is first operated for a preset time (first set duration) at the initial outlet air temperature set by the user. After this time, the air conditioner will fine tune the outlet air temperature according to the current mode of operation (cooling or heating). For example, in a cooling mode, if the ambient temperature is higher than the set temperature, the air conditioner may slightly lower the outlet air temperature; in the heating mode, if the ambient temperature is lower than the set temperature, the air conditioner may slightly raise the outlet air temperature.
It will be appreciated that the fine tuning described above is to better accommodate ambient temperature variations, ensure user comfort during sleep, while optimizing energy use efficiency.
And S3, after the fine adjustment of the air outlet temperature is finished, controlling and adjusting the power supply mode of the solar air conditioner according to the working mode and the current operation parameters of the solar air conditioner.
In step S3, after the fine adjustment of the air outlet temperature is completed, the air conditioner adjusts the power supply mode according to the working mode and the current operation parameters (such as indoor and outdoor temperature, humidity, etc.). This may include preferentially using solar power or switching to an energy storage battery or mains power when the solar energy is insufficient to meet demand. The system will optimize the power supply strategy according to the energy supply situation and the energy saving objective.
It can be understood that through the intelligent control power supply mode, the system can utilize solar energy to the maximum extent when guaranteeing the normal operation of the air conditioner, and reduce the dependence on other energy sources, thereby realizing energy conservation.
In summary, the core of the solar air conditioner control method of the invention is to provide a comfortable indoor environment during the sleeping period of the user through an intelligent control strategy, and simultaneously realize the efficient utilization of energy. The method is started by receiving the sleep mode signal, then the air outlet temperature is finely adjusted according to the environmental condition and the working mode, and finally the power supply mode is adjusted according to the actual energy supply condition. The whole process aims at improving energy efficiency, reducing energy consumption and simultaneously ensuring comfort level of a user during sleeping. In this way, the solar air conditioning system can better adapt to different environmental conditions, and provides a more environment-friendly and economical solution for users.
In the related art, the existing air conditioner does not fully utilize solar energy as energy, but mainly relies on commercial power, and lacks intelligent regulation function, and can not automatically adjust operation parameters according to real-time environmental conditions and user requirements, so that the energy is not flexible enough to use, and the optimal energy efficiency can not be realized under different conditions. In addition, the conventional sleep mode may operate only for a time set by a user without dynamic adjustment according to solar power supply conditions and indoor and outdoor temperature changes. This may result in underutilization when solar energy is sufficient or excessive reliance on mains when solar energy is insufficient.
In summary, in order to solve the technical defects existing in the related art, the present invention provides a control method of a solar air conditioner, which has the following advantages compared with the related art: (1) energy is derived from self-contained: according to the scheme, the solar photovoltaic panel is integrated, so that the air conditioner can directly utilize solar energy to supply power when the solar energy is sufficient, dependence on commercial power is reduced, and the self-sufficient energy supply capacity is improved. (2) intelligent temperature regulation: through intelligent control system, the air conditioner can be according to indoor outer temperature variation and user's settlement, automatic fine setting air-out temperature to adapt to different environmental conditions and user's demand, improve energy efficiency and comfort level. (3) dynamic power management: according to the scheme, the power supply mode can be intelligently switched according to the solar energy supply condition and the electric quantity of the energy storage battery, renewable energy sources are preferentially used, and optimal distribution of the energy sources is achieved. (4) energy-saving optimization: in the sleep mode, the air conditioner not only can adjust the temperature according to user setting, but also can perform energy-saving optimization according to real-time environment data, such as reducing refrigeration load when the temperature is reduced at night or increasing refrigeration efficiency when the temperature is increased in daytime. (5) environmental adaptation enhancement: according to the scheme, through an intelligent control strategy, the air conditioner can be better adapted to different seasons and climate changes, and a more stable indoor environment is provided. (6) user comfort enhancement: through intelligent regulation and optimization, this scheme can reduce the energy consumption when guaranteeing the comfortable sleep of user, provides more humanized user experience.
According to some embodiments of the present invention, according to a current working mode of a solar air conditioner, a step of fine tuning an air outlet temperature of the solar air conditioner specifically includes:
if the solar air conditioner is determined to be in a heating mode currently, controlling the air outlet temperature to drop by a first regulating temperature on the basis of the initial air outlet temperature;
and if the solar air conditioner is in the refrigeration mode currently, controlling the air outlet temperature to rise by a second regulation temperature on the basis of the initial air outlet temperature.
In this embodiment, the system first needs to identify whether the air conditioner is in the heating mode or the cooling mode.
Once it is determined that the air conditioner is in the heating mode, the system controls the outlet air temperature to drop by a predetermined first regulation temperature based on the initial setting. This regulated temperature is a preset value for fine tuning the indoor temperature during sleep of the user to maintain comfort while saving energy.
Similarly, if the air conditioner is in the cooling mode, the system controls the outlet air temperature to rise by a predetermined second regulation temperature based on the initial setting. The fine tuning is to reduce the operation load of the air conditioner while ensuring comfortable sleep of the user, thereby saving energy.
Therefore, by fine adjustment of the air outlet temperature, the system can reduce the running load of the air conditioner on the premise of not affecting the comfort level of users, thereby reducing the energy consumption. And, intelligent regulation ensures that the user enjoys proper indoor temperature during sleeping, improves sleep quality. In addition, the system can be automatically adjusted according to different working modes (heating or refrigerating) and environmental conditions, so that the adaptability and the flexibility of the air conditioning system are improved.
For example, in the sleep mode, if the solar air conditioner is continuously operated for one hour at the initial air outlet temperature, when the air conditioner is in the heating mode, the air outlet temperature is controlled to be reduced by 1 ℃ on the basis of the initial air outlet temperature; if the air conditioner is in the refrigeration mode currently, the air outlet temperature is controlled to rise by 0.5 ℃ on the basis of the initial air outlet temperature.
According to some embodiments of the present invention, after the fine adjustment of the air outlet temperature is completed, according to the working mode and the current operation parameters of the solar air conditioner, the step of controlling and adjusting the power supply mode of the solar air conditioner specifically includes:
After the fine adjustment of the air outlet temperature is completed, the current running power of the solar air conditioner and external power supply information are obtained, wherein the external power supply information at least comprises solar power supply quantity;
And controlling and adjusting a power supply mode of the solar air conditioner according to the working mode, the current running power and the external power supply information, wherein the power supply mode comprises a solar power supply mode, a mains supply mode and a hybrid power supply mode.
In this embodiment, after the fine adjustment of the air outlet temperature is completed, the system may measure the real-time running power of the air conditioner and collect external power supply information, especially the power supply amount of solar energy. This information is critical to determining the next power mode.
According to the working mode (heating or cooling), the current running power and the external power supply information (solar energy power supply amount) of the air conditioner, the system can automatically select the most suitable power supply mode. If the solar power supply is sufficient, the system may prefer a solar power supply mode; if the solar power supply is insufficient, the system may switch to a mains power mode or a hybrid power mode.
The solar power supply mode refers to that the air conditioner is completely operated by the power provided by a solar power supply system (such as a photovoltaic panel). The mains supply mode refers to the fact that the air conditioner relies on a conventional mains supply. The hybrid power supply mode refers to that the air conditioner simultaneously uses solar power supply and mains supply power supply, and the proportion of the solar power supply and the mains supply power supply is dynamically adjusted according to actual conditions.
Therefore, the system can dynamically adjust the power supply strategy according to the real-time data, and the adaptability to different environmental conditions is improved. Moreover, by intelligently selecting the power supply mode, the system can utilize solar energy to the maximum extent when the solar energy is sufficient, so that dependence on commercial power is reduced, and the energy cost is reduced.
Hereinafter, the specific description of the air conditioner power mode adjustment will be made by taking the cooling mode and the heating mode as examples, respectively.
First, the adjustment of the power supply mode of the solar air conditioner in the heating mode will be described in detail below as an example.
According to some embodiments of the present invention, when the working mode is a heating mode, the step of controlling and adjusting the power supply mode of the solar air conditioner according to the working mode, the current running power and the external power supply information specifically includes:
if the solar energy supply quantity meets the current running power, the solar air conditioner is controlled to be disconnected with the mains supply, so that the power supply mode is switched to the solar power supply mode;
And if the solar power supply quantity does not meet the current running power, controlling and adjusting parameters of the solar air conditioner according to the outdoor environment temperature acquired in advance, acquiring the current running power again after the parameter adjustment of the solar air conditioner is completed, and adjusting a power supply mode according to the current running power.
Further, according to the pre-acquired outdoor environment temperature control, the operation parameters of the solar air conditioner are adjusted, after the parameter adjustment of the solar air conditioner is completed, the current operation power is acquired again, and the power supply mode is adjusted according to the current operation power, specifically comprising the steps of:
If the outdoor environment temperature is determined to be higher than the first environment temperature, controlling the running frequency of the compressor to be reduced, controlling the exhaust temperature of the compressor not to exceed a limit value and/or controlling the opening degree of the electronic expansion valve to be reduced;
after the parameter adjustment of the solar air conditioner is completed, the current running power is obtained again;
and if the solar energy supply quantity meets the current running power, the solar air conditioner is controlled to be disconnected with the mains supply, so that the power supply mode is switched into the solar power supply mode.
In the above embodiment, the working principle is to dynamically adjust the power supply mode and the operation parameters according to the solar power supply capacity, the outdoor environment temperature and the operation power of the air conditioner by using an intelligent control strategy so as to realize energy efficiency optimization and energy utilization maximization.
In the working process, the system firstly detects the relation between the solar energy power supply quantity and the running power of the air conditioner, and then adjusts the running parameters of the air conditioner, such as the frequency of the compressor and the opening of the electronic expansion valve, according to the requirements. By these adjustments, the system aims at reducing energy consumption while ensuring user comfort. Throughout the process, the system is continuously monitored and adjusted to accommodate environmental changes and energy supply conditions.
Specifically, after the first temperature fine adjustment, the system first checks whether the solar power supply is sufficient to support the current operating power of the air conditioner. If the solar energy supply quantity is enough, the system is used for controlling the air conditioner to be disconnected with the mains supply and switching to a solar energy supply mode. Therefore, renewable energy sources can be fully utilized, and dependence on commercial power is reduced.
If the amount of solar power is insufficient to support the operation of the air conditioner, the system will adjust the operating parameters of the air conditioner based on the outdoor ambient temperature to reduce energy consumption. This may include reducing the operating frequency of the compressor, controlling the compressor discharge temperature not to exceed a limit value, and adjusting the opening of the electronic expansion valve.
Further, the system may detect an outdoor ambient temperature. If the outdoor temperature is above a preset first ambient temperature threshold, the system will take steps to reduce the operating frequency of the compressor to reduce energy consumption. At the same time, it is ensured that the compressor discharge temperature does not exceed a safe limit value, and it is possible to adjust the opening of the electronic expansion valve to optimize the refrigerant flow. For example, the first ambient temperature may take on a value of 0 ℃.
After the operating parameters of the air conditioner are adjusted, the system again measures the current operating power to evaluate the effect of the adjustment. If the solar energy power supply quantity can meet the current running power after parameter adjustment, the system controls the air conditioner to be disconnected with the mains supply again and switches back to the solar energy power supply mode. If not, the system may continue to adjust parameters or maintain the hybrid power mode.
Therefore, through intelligent regulation, the system can reduce the energy consumption of the air conditioner when the solar power supply is insufficient, and the energy utilization efficiency is improved. In addition, the system can automatically adjust the operation strategy according to the real-time environment temperature and the solar power supply condition, and the adaptability and the reliability of the system are improved. In addition, while conserving energy, the system still focuses on user comfort, ensuring that the indoor temperature remains within the user-set range.
Next, a detailed description will be given of an example of adjustment of the power supply mode in which the solar air conditioner is in the cooling mode.
According to other embodiments of the present invention, when the working mode is a cooling mode, the step of controlling and adjusting the power supply mode of the solar air conditioner according to the working mode, the current running power and the external power supply information specifically includes:
if the solar energy supply quantity meets the current running power, the solar air conditioner is controlled to be disconnected with the mains supply, so that the power supply mode is switched to the solar power supply mode;
and if the solar power supply quantity does not meet the current running power, adjusting the parameters of the solar air conditioner, acquiring the current running power again after the parameters of the solar air conditioner are adjusted, and adjusting the power supply mode according to the current running power.
Further, the method comprises the steps of adjusting parameters of the solar air conditioner, acquiring current running power again after the parameters of the solar air conditioner are adjusted, and adjusting a power supply mode according to the current running power, wherein the method specifically comprises the following steps:
After the solar air conditioner continuously operates for a second set period of time at the fine-tuned air outlet temperature, performing secondary fine tuning on the air outlet temperature, wherein the secondary fine tuning comprises controlling the air outlet temperature to rise to a second regulation temperature;
And after the secondary fine adjustment of the air outlet temperature is completed, acquiring the current running power again, and adjusting the power supply mode according to the current running power.
In the above embodiment, the system first evaluates whether the current solar power supply can meet the operating power demand of the air conditioner. This is to determine if solar power can be relied upon entirely, thereby reducing utility usage.
If the solar energy supply quantity is enough, the system is used for controlling the air conditioner to be disconnected with the mains supply and switching to a solar energy supply mode. This step is to maximize the use of solar energy, achieving self-sufficiency of energy.
If the solar energy supply is insufficient, after the air conditioner is operated for a period of time at the air outlet temperature after the fine adjustment, the system performs secondary fine adjustment (for example, the air outlet temperature is controlled to rise by 0.5 ℃), and the air outlet temperature is usually raised, so that the operation power of the air conditioner is further reduced, and meanwhile, the indoor comfort is maintained. The system then adjusts the power mode further based on the current operating power.
Further, the step of adjusting the power supply mode according to the current operation power specifically includes:
if the solar energy supply quantity meets the current running power, the solar air conditioner is controlled to be disconnected with the mains supply, so that the power supply mode is switched to the solar power supply mode;
And if the solar power supply quantity does not meet the current running power, controlling and adjusting parameters of the solar air conditioner according to the outdoor environment temperature acquired in advance, acquiring the current running power again after the parameter adjustment of the solar air conditioner is completed, and adjusting a power supply mode according to the current running power.
In this embodiment, after the system fine-adjusts the air outlet temperature, the power supply mode is adjusted again according to the current running power.
If the solar energy supply quantity meets the operation power, the system can automatically control the air conditioner to be disconnected with the mains supply and switch to a solar energy supply mode. Therefore, renewable energy sources can be preferentially used, and dependence on commercial power is reduced.
If the solar energy supply quantity is insufficient to meet the operation power, the system can further adjust the operation parameters of the air conditioner according to the pre-acquired outdoor environment temperature. For example, the operation frequency of the compressor is adjusted, the opening degree of the electronic expansion valve is changed, etc., so as to reduce the energy consumption of the air conditioner.
After the parameters are adjusted, the system can measure the current running power of the air conditioner again, and the power supply mode is adjusted according to the current running power.
Further, according to the pre-acquired outdoor environment temperature control, the operation parameters of the solar air conditioner are adjusted, after the parameter adjustment of the solar air conditioner is completed, the current operation power is acquired again, and the power supply mode is adjusted according to the current operation power, specifically comprising the steps of:
If the outdoor environment temperature is less than the second environment temperature, controlling the running frequency of the compressor to be reduced, the exhaust temperature of the compressor not to exceed a limit value and/or the opening of the electronic expansion valve to be reduced;
after the parameter adjustment of the solar air conditioner is completed, the current running power is obtained again;
and if the solar energy supply quantity meets the current running power, the solar air conditioner is controlled to be disconnected with the mains supply, so that the power supply mode is switched into the solar power supply mode.
In this embodiment, if the amount of solar power supply is insufficient to meet the operating power, the system monitors the outdoor ambient temperature in real time through an outdoor temperature sensor. If the outdoor temperature is below a preset second ambient temperature (this temperature threshold is set according to the system design and user comfort requirements), the outdoor temperature is considered to be low.
In case that the outdoor temperature is low, the system may perform the following operations:
(1) Reducing the compressor operating frequency: the operating speed of the compressor is reduced, thereby reducing the cooling capacity of the air conditioner, as a lower outdoor temperature means that the room may not need much cooling.
(2) Controlling the exhaust temperature: ensuring that the discharge temperature of the compressor does not exceed the set safety and efficiency limits to prevent overheating or efficiency degradation of the compressor.
(3) Reducing the opening degree of the electronic expansion valve: the flow of the refrigerant is reduced, and the refrigeration load of the air conditioner is further reduced.
After the adjustment of the air conditioner parameters is completed, the system will again measure the real-time operating power of the air conditioner. Based on the retrieved operating power, the system determines whether the solar energy supply is sufficient to support the current operating demand of the air conditioner. If the solar energy supply quantity is enough, the system is used for controlling the air conditioner to be disconnected with the mains supply and switching to a solar energy supply mode. This helps to further save energy costs and reduce environmental impact.
Therefore, through intelligent regulation, the system can reduce the energy consumption of the air conditioner when the solar power supply is insufficient, and the energy utilization efficiency is improved. And solar energy is preferentially used for supplying power, so that the consumption of commercial power is reduced, and the electricity charge expenditure of a user is reduced. In addition, the system is energy-saving and still focuses on the stability of indoor temperature, so that comfortable experience of users is ensured.
It should be explained that, in the adjustment step of the solar air conditioner control in the above-described cooling mode and heating mode, a specific judgment method of "the solar power supply amount satisfies/does not satisfy the current operation power" is as follows: on the one hand, the system monitors the solar energy generating capacity in real time through a sensor connected to the solar photovoltaic panel, the sensor can measure the voltage and the current of the photovoltaic panel so as to calculate the real-time power output, and on the other hand, the power sensor or the intelligent controller inside the air conditioner can monitor the power consumption of the air conditioner in real time, and the power consumption can be realized by measuring the current and the voltage. And then, comparing the real-time monitored solar energy supply energy with the running power of the air conditioner by the system. If the solar power supply amount is greater than or equal to the operation power of the air conditioner, the solar power supply amount is considered to be sufficient.
It is assumed that the real-time power output of the solar photovoltaic panel is 3 kilowatts (kW) and the real-time operation power of the air conditioner is 2.5kW at a certain sunny afternoon. At this time, the solar power supply amount (3 kW) is greater than the operation power (2.5 kW) of the air conditioner, so the solar power supply amount is sufficient. The system will control the air conditioner to switch to the solar power mode while the mains connection may be disconnected.
If the real-time power output of the solar photovoltaic panel is reduced to 1.5 kilowatts (kW) on a cloudy day, and the operating power of the air conditioner is still 2.5kW, the solar power supply is insufficient to support the operation of the air conditioner. In this case, the system may take energy saving measures such as reducing the operating frequency of the air conditioner or switching to a mains supply mode to ensure the normal operation of the air conditioner.
