Document Type and Number:
WIPO Patent Application WO/2023/142261
Kind Code:
A1
Abstract:
The present invention provides a photovoltaic air conditioner and a control method therefor and a photovoltaic air conditioner system. The photovoltaic air conditioner comprises a first compressor, a first inverter device, a first switch circuit, and a main control board. The main control board is configured to when the photovoltaic power generation is satisfied and the photovoltaic air conditioner is in an air supply or standby state, control the first inverter device to convert direct current from a photovoltaic assembly into alternating current, and control the first switch circuit to connect the first inverter device to a power grid, such that the alternating current obtained by converting is output to the power grid; and when the photovoltaic power generation is satisfied and the photovoltaic air conditioner is in a cooling or heating state, control the first inverter device to convert direct current from the photovoltaic assembly into alternating current, and control the first switch circuit to connect the first inverter device to the first compressor, such that the alternating current obtained by converting is output to the first compressor.
