It is understood that the first preset value and the second preset value are both values stored in advance. The first preset value is a higher temperature at which the user tends to turn on the air conditioner for cooling. For example, the first preset value may be any value from 30 ℃ to 40 ℃, and the second preset value may be any value from-10 ℃ to 10 ℃.
The wind-solar energy storage system provided by the embodiment of the invention can comprise solar photovoltaic power generation equipment, a wind driven generator and a storage battery pack. The air conditioner of the embodiment of the invention at least comprises an indoor unit, an outdoor unit and a compressor.
In some embodiments, an inverter is disposed between the storage battery pack of the wind-solar energy storage system and the air conditioner, and the inverter can convert direct current output by the storage battery pack into alternating current to supply power to the air conditioner.
In other embodiments, the air conditioner is powered by direct current.

In some embodiments, if the first predetermined value is 40 ℃, the second predetermined value is 0 ℃, and the detection temperature is 35 ℃. Under the condition, the real-time storage electric quantity and the real-time power generation power of the wind and light energy storage system are determined so as to judge whether the electric energy provided by the wind and light energy storage system meets the use requirement of the air conditioner.
And step 130, determining a target frequency of a compressor of the air conditioner based on the real-time stored electric quantity and the real-time generated power.
It will be appreciated that the compressor of the air conditioner may operate at different frequencies. When the compressors work according to different frequencies, the power of the compressors is different, and the power consumption of the compressors is different at the same time.
In the embodiment, because the power consumption of the compressor of the air conditioner accounts for a very large ratio, when the power consumption of the air conditioner and the power supply of wind and light energy storage are considered, the target frequency of the compressor of the air conditioner can be determined by combining the real-time stored power and the real-time generated power of the wind and light energy storage system. In this case, the wind-solar energy storage system can meet the requirement that the compressor of the air conditioner works according to the target frequency.
And 140, controlling the air conditioner to supply power through the wind and light energy storage system, and controlling a compressor of the air conditioner to work according to the target frequency.
It will be appreciated that the determined target frequency takes into account the real-time stored power and the real-time generated power of the wind and light energy storage system, in which case the air conditioner may be controlled to be powered by the wind and light energy storage system and the compressor of the air conditioner may be controlled to operate at the target frequency.
In this embodiment, by detecting the target object in the target area or the off state of the air conditioner, it can be determined that the user has not turned on the air conditioner in this case, and the user cannot turn on the air conditioner automatically for a while, in this case, there is a scenario in which the air conditioner is turned on automatically in advance.
Further, the necessity of starting the operation of the air conditioner is further determined by detecting the temperature of the target area to obtain the detected temperature. Under the condition, the real-time storage electric quantity and the real-time power generation power of the wind and light energy storage system are further determined, and whether the wind and light energy storage system meets the use requirement of the air conditioner or not can be determined.
According to the control method of the air conditioner, provided by the embodiment of the invention, the target frequency of the compressor meeting the power supply condition can be determined by detecting the personnel condition in the target area or the opening and closing state of the air conditioner and determining the real-time storage electric quantity and the real-time power generation power of the energy storage and power supply system at the environmental temperature of the air conditioner needing to be opened, so that the stored electric energy of the wind and light energy storage system is automatically utilized, the energy waste is avoided, the temperature condition of the target area is automatically improved, and the user experience is improved.
In some embodiments, at step 130: after the air conditioner is controlled to be powered by the wind and light energy storage system, the control method of the air conditioner in the embodiment of the invention further comprises the following steps: and detecting the residual electric quantity of the wind and light energy storage system, and controlling the air conditioner to supply power through the commercial power under the condition that the residual electric quantity is smaller than a third preset value.
It will be appreciated that the third preset value may be stored in advance. If the maximum electric quantity stored by the wind and light energy storage system is W, the third preset value may be a × W, where a is a constant greater than 0 and less than 0.5. For example, a may be 0.3.
And under the condition that the residual electric quantity is less than the third preset value, the residual electric quantity of the wind and light energy storage system is too small, and the continuous use of the wind and light energy storage system may exhaust electric energy so as not to meet the use requirement of the air conditioner. After the wind and light energy storage system is stopped supplying power to the air conditioner, the wind and light energy storage system can be charged through solar energy and wind energy.
Under the condition, the air conditioner is switched to the commercial power to supply power, so that the stability of the air conditioner in the subsequent use process can be guaranteed.
In some embodiments, at step 130: after the air conditioner is controlled to be powered by the mains supply, the control method of the air conditioner further comprises the steps of detecting the residual electric quantity of the wind and light energy storage system, and controlling the air conditioner to be powered by the wind and light energy storage system and the mains supply at the same time under the condition that the residual electric quantity is larger than a fourth preset value.
It will be appreciated that the fourth preset value may be stored in advance. If the maximum electric quantity stored by the wind and light energy storage system is W, the fourth preset value may be b × W, where b is a constant greater than 0.5 and less than 1. For example, b may be 0.6.
It can be understood that, in the case that the remaining capacity is less than the third preset value, the remaining capacity of the wind-solar energy storage system is too small. After the wind and light energy storage system is stopped supplying power to the air conditioner, the wind and light energy storage system can be charged through solar energy and wind energy.
After the wind and light energy storage system is charged for a period of time, the remaining electric quantity of the wind and light energy storage system is detected, and under the condition that the remaining electric quantity is larger than a fourth preset value, the wind and light energy storage system can be determined to continue to stably supply power to the air conditioner. In this case, the air conditioner is controlled to be simultaneously supplied with power through the wind and light energy storage system and the commercial power.
In the embodiment, the residual electric quantity of the wind and light energy storage system is detected, and the wind and light energy storage system is continuously used for supplying power to the air conditioner when the residual electric quantity is large, so that the maximization of new energy utilization can be realized, and the effect of saving energy is further realized.
In some embodiments, step 130: the target frequency of the compressor of the air conditioner is determined based on the real-time stored power amount and the real-time generated power, and may include the following processes.
It should be noted that, when the real-time stored electricity amount is greater than or equal to the fifth preset value, the real-time generated power may be determined as the total power of the air conditioner, and then the target frequency may be determined based on the total power of the air conditioner.
If the maximum electric quantity stored by the wind and light energy storage system is W, the fifth preset value may be c × W, where c is a constant greater than 0.8 and less than or equal to 1. For example, c may be 1.
It is understood that the real-time generated power may be generated power when the real-time stored power is detected and the target area detection temperature is obtained.
