Abstract

The invention discloses an air conditioner, which comprises a compressor, an indoor heat exchanger, an outdoor heat exchanger, a refrigerant heater, a throttling device, a temperature sensor and a controller; the refrigerant heater is connected in series between the indoor heat exchanger and the outdoor heat exchanger; the temperature sensor is arranged on the outdoor heat exchanger and is used for detecting the evaporating temperature of the outdoor heat exchanger after the air conditioner is started to perform heating; the controller is connected with the temperature sensor and is used for judging the evaporating temperature of the outdoor heat exchanger, switching on the refrigerant heater to heat refrigerant when the evaporating temperature is lower than or equal to a first preset temperature and switching off the refrigerant heater when the evaporating temperature is higher than or equal to a second preset temperature. The air conditioner can utilize the control process of heating the refrigerant to realize the un-reverse defrosting of the air conditioner; moreover, during defrosting, the indoor heat exchanger can continuously perform heating to ensure the comfort of a room; furthermore, the structure is simple, and the operation is reliable. The invention also discloses a control method for the air conditioner with the refrigerant heating function.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a control method of an air conditioner with a refrigerant heating function and an air conditioner with a refrigerant heating function. Background technique [0002] When an air conditioner with a heat pump system (hereinafter referred to as an air conditioner) is used under low temperature conditions, after a period of operation, the heat exchanger of the external unit will frost, which increases the thermal resistance and wind resistance, which is not conducive to heat exchange. In order to make the air conditioner operate normally, it is often necessary to remove and melt the frost of the external unit. [0003] The main defrosting method of the existing air conditioner is to switch the four-way valve to carry out the refrigeration cycle. Although such a defrosting method can completely remove the frost on the heat exchanger, the indoor unit stops running during the d...
