Document Type and Number:
WIPO Patent Application WO/2020/191976
Kind Code:
A1
Abstract:
Provided are an air conditioner control method and device, and an air conditioner. The air conditioner comprises an outdoor condenser, an indoor evaporator, a first electronic expansion valve, a throttle valve and a heat dissipation coolant pipe provided in an electric control box. The outdoor condenser is connected with a first end of the heat dissipation coolant pipe via the first electronic expansion valve. The indoor evaporator is connected with a second end of the heat dissipation coolant pipe via the throttle valve. The first electronic expansion valve is used to throttle a coolant in a heating mode. The throttle valve is used to throttle the coolant in a cooling mode. The air conditioner control method and device, and the air conditioner of the present invention employ a heat dissipation coolant pipe to dissipate heat from an electric control box of an air conditioner, thereby timely removing heat generated by the electric control box, lowering element temperatures, and improving the reliability and service life of the air conditioner. The invention enables a variable frequency air conditioner to operate at a high operating frequency and reach high output power efficiency under high temperatures, thereby maximizing advantages of the variable frequency air conditioner, and meeting user requirements.
