The invention relates to the technical field of air conditioners, and provides an oil return control method and device of a solar air conditioner and an air conditioning system.The method comprises the steps that when the solar air conditioner is in a low-frequency running state, whether a preset oil return triggering condition is met or not is judged; when conditions are met, the current oil temperature of refrigerant oil is obtained; when the oil temperature is smaller than a preset oil return temperature threshold value, a stepped frequency increasing strategy for the compressor to enter an oil return mode is determined, and the compressor is controlled to operate according to the stepped frequency increasing strategy; and if the solar power supply system does not meet the power required for maintaining the operation of the stepped frequency raising strategy, triggering the multi-energy complementary machine. The compressor is controlled to gradually increase the frequency according to the stepped frequency increasing strategy, so that the frequency of the compressor is in smooth transition, transient load impact in the oil return process is buffered, stable operation of the compressor is guaranteed, and the service life of an air conditioning system is prolonged; and auxiliary energy is introduced through a multi-energy complementary mechanism for power compensation, stable power supply in the oil return process is guaranteed, and then the operation reliability of the system is improved.

This invention relates to the field of air conditioning technology, and provides a control method, device, and solar air conditioning system for a solar-powered air conditioner. The method includes: when the solar-powered air conditioner is in operation mode powered by a solar power module, acquiring the current operating frequency of the compressor and the current ambient temperature; determining, based on the current operating frequency and ambient temperature, that a low-frequency oil return trigger condition is met; responding to the low-frequency oil return trigger condition, executing an oil return control operation, which includes controlling the compressor to increase its operating frequency from the current frequency to a target frequency; and activating an auxiliary power supply unit to provide compensating power to the compressor. By determining that the low-frequency oil return trigger condition is met based on the compressor's current operating frequency and ambient temperature, when executing oil return control, the compressor is increased to a target frequency lower than the standard oil return frequency, improving user comfort during the air conditioner's oil return process; simultaneously, the auxiliary power supply unit is activated to provide compensating power, ensuring the reliability of the compressor's oil return process.
