Abstract

The invention discloses a defrosting control method. The method is applied to the defrosting control device. The device comprises a compressor, wherein an electronic expansion valve is connected withthe compressor. The method comprises steps that after a defrosting mode is started, the exhaust temperature of the compressor is obtained, and the exhaust temperature is compared with the preset exhaust temperature; the opening degree of the electronic expansion valve is adjusted according to the exhaust temperature comparison result; after preset time, the exhaust pressure of the compressor is compared with the preset exhaust pressure, and the opening degree of the electronic expansion valve is adjusted according to the exhaust pressure comparison result. The invention further discloses a defrosting control device, an air conditioner and a readable storage medium. The method is advantaged in that the flow opening degree of the electronic expansion valve is dynamically adjusted based on exhaust parameters of the compressor so that the refrigerant circulation amount of the compressor is adjusted, defrosting can be effectively carried out, and the defrosting time is shortened.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to a defrosting control method, a defrosting control device, an air conditioner and a readable storage medium. Background technique [0002] When the air conditioner is heating in winter, frosting is a common phenomenon in the system operation. When the surface temperature of the outdoor heat exchanger is lower than the air dew point, the water vapor in the air will condense, and when the temperature is lower than 0°C, condensation will occur. It will accumulate on the surface of the outdoor heat exchanger to form frost. When the frost reaches a certain thickness, the heating capacity of the air conditioner will become lower and lower. Therefore, in order to ensure the heating effect, it is necessary to defrost the outdoor heat exchanger. The defrosting of the outdoor heat exchanger can be performed by adjusting the operating parameters of the electronic expansion v...
