Solar air conditioner, method and device for controlling solar air conditioner

摘要

Disclosed is a method for controlling a solar air conditioner, which includes: a detection step, detecting the change situation of a DC voltage outputted by an inverter of the solar air conditioner when it is detected that the solar air conditioner enters an energy-saving control mode; and a judging step, adjusting an operating frequency of a compressor of the solar air conditioner according to the change situation of the DC voltage, so that the solar air conditioner uses a solar cell to supply power. Thus, solar energy can be used to the maximum degree, the problem that there is a need to supply power by a mains power supply because the power supplied for the solar energy is insufficient is avoided, and the cost is saved. Further a device for controlling the solar air conditioner and the solar air conditioner are provided.
