and S100, acquiring the current solar power supply power of the air conditioner.
S200, in response to the fact that the running frequency of the air conditioner compressor corresponding to the current solar power supply does not reach the oil return preset frequency, the compressor is controlled to run in an oil return mode at the running frequency section under the current solar power supply.
The preset oil return frequency is a set oil return frequency, and the oil return frequency refers to the optimal oil return operation frequency determined in all oil return tests, namely the frequency with the highest oil return amount or oil return rate. The oil return test is a test for testing the oil return effect under the condition that the external temperature is 21 ℃ through a 15-meter connecting pipe (namely an oil return pipeline).
And, the operable frequency section is a frequency interval in which the oil return operation can be stabilized under the current solar power supply.
The oil return control method of the air conditioner compressor provided by the embodiment of the invention is mainly applied to an oil return control scene that no commercial power exists and only new energy solar energy exists and the air conditioner compressor is started based on the solar energy.
According to one embodiment of the invention, the present solar powered power comprises: a first solar power supply; the operable frequency bands include: the first operable frequency section is a first frequency interval from the lowest frequency of the compressor to the intermediate frequency of the compressor, the intermediate frequency is greater than the lowest frequency and less than the preset oil return frequency, and the operating frequency of the compressor under the first solar power supply is the first frequency interval.
Wherein, the lowest frequency means: determining the running frequency of the compressor when the oil return is qualified after continuously running for 6-8 hours at low temperature of 21 ℃ of the external temperature through an oil return test; and, the intermediate frequency may be a difference between the oil return preset frequency and the lowest frequency.
According to the embodiment of the invention, the operation frequency of the compressor under the first solar power supply power is set to be the first frequency interval, so that the oil return quantity or the oil return rate of the compressor under the illumination intensity corresponding to the first solar power supply power is at least qualified, the oil return effect under the current illumination intensity is ensured, the compressor is protected, the service life of the compressor is favorably prolonged, and the stable and reliable operation of the air conditioner is ensured.
According to one embodiment of the invention, the present solar powered power further comprises: the second solar power supply power is larger than the first solar power supply power; the operable frequency band further comprises: and the second operable frequency section is a second frequency interval from the intermediate frequency of the compressor to the oil return preset frequency of the compressor, and the operating frequency of the compressor under the second solar power supply is the second frequency interval.
The first frequency interval may be greater than or equal to the lowest frequency and less than a frequency interval to the intermediate frequency, and the second frequency interval may be greater than or equal to the intermediate frequency and less than the preset oil return frequency.
The embodiment of the invention can provide different compressor oil return operation frequencies according to different solar power supply powers, namely under different illumination intensities, and can well adapt to the change of the illumination intensity, thereby ensuring the oil return effect under the current illumination intensity, protecting the compressor and being beneficial to better and stable operation of the air conditioner.
According to an embodiment of the present invention, the method for controlling the compressor to operate in return oil mode in the operable frequency range under the current solar power supply further comprises the following steps: acquiring the outdoor environment temperature; and determining the oil return time of the compressor according to the outdoor environment temperature.
It can be understood that the oil return effect of the compressor is easily affected by the external temperature, and therefore, when the compressor returns oil, the oil return time under different environmental temperatures is determined by detecting the external temperature and according to the detected external temperature, and the oil return effect under the current environmental temperature can be improved.
According to an embodiment of the present invention, the step of determining the oil return duration of the compressor according to the outdoor environment temperature specifically includes:

and when the outdoor environment temperature is greater than or equal to the target preset temperature, controlling the compressor to perform oil return operation for a second oil return time length, wherein the second oil return time length is less than the first oil return time length.
When the outdoor environment temperature is lower than the target preset temperature, namely the outside temperature is relatively low, the oil return effect is poor, and at the moment, the oil return effect can be improved as much as possible by continuously returning oil for a relatively long first oil return time, so that the stable starting operation of the compressor is ensured; when the outdoor environment temperature is greater than or equal to the target preset temperature, namely the external temperature is relatively high, at the moment, the intersolubility of the compressor lubricating oil and the refrigerant is good, the oil return duration time can be correspondingly shortened, and the quick start of the compressor can be realized on the premise of ensuring the oil return effect.

In a specific example, when the current outdoor environment temperature is detected to be less than 18 ℃, the first oil return time is 8min, namely the oil return time lasts for 8 minutes; and when the current outdoor environment temperature is detected to be more than or equal to 18 ℃, the second oil return time is 5min, namely the oil return time lasts for 5min.
According to an embodiment of the present invention, the oil return control method of the air conditioner compressor further includes the steps of: when the compressor performs oil return operation in a first oil return duration, controlling the solar energy storage device to supply power to the heater, and heating an oil return pipeline of the compressor in a first heating duration through the heater; and when the compressor performs oil return operation for a second oil return time period, controlling the heater to heat the oil return pipeline of the compressor for a second heating time period, wherein the second heating time period is shorter than the first heating time period.
Specifically, the photovoltaic panel is electrically connected with a solar energy storage device, the solar energy storage device is respectively electrically connected with the air conditioner and the heater, and the heater is arranged on an oil return pipeline of the compressor. The electric energy generated by the photovoltaic panel is transmitted to the solar energy storage device for storage, when a power failure phenomenon occurs, the solar energy storage device can be used for respectively supplying power to the air conditioner and the heater, and when the compressor performs oil return operation for a first oil return time period, namely the external temperature is low, at the moment, the heater is controlled to heat an oil return pipeline of the compressor for a certain time period, so that the oil return effect can be further improved; when the compressor performs oil return operation in the second oil return time period, because the temperature under the working condition is relatively low, at this time, the heater can be controlled to heat the oil return pipeline of the compressor in the duration time period which is less than the first heating time period, so that the oil return effect can be improved on one hand, and on the other hand, the operation time of the heater can be shortened, and the energy-saving effect is achieved.
The specific types of the solar energy storage device and the heater of the invention are not particularly limited, for example, the solar energy storage device may be a storage battery, and the heater may be a heating wire.
