|Title:||CONTROL METHOD AND DEVICE FOR AIR CONDITIONER, AND AIR CONDITIONER|
A control method for an air conditioner, comprising: acquiring an outdoor temperature threshold and an air supply temperature condition; acquiring, when the air conditioner is running in heat mode, an outdoor temperature, an outdoor machine temperature, and a radiator temperature; and when the outdoor temperature is no greater than the outdoor temperature threshold and the outdoor machine temperature is no greater than a critical frost temperature, adjusting the opening degree of a first throttling device (801) to make the radiator (7) temperature satisfy the air supply temperature condition. Further provided are a control device for an air conditioner, and an air conditioner. Said method can control a first throttling device (801) to be turned on when an outdoor temperature is lower than a critical frost temperature, so that refrigerants flowing out of a heat exchanger of an indoor machine can exchange heat with an electric control element through a radiator (7), thereby increasing the heat load of the refrigerants supplied by means of the after heat generated by the electric control element, such that the heat-exchanged refrigerants can reach a refrigerant state, required by air-supplying and enthalpy-increasing, of a compressor (3), improving the working performance of the compressor (3).
