Abstract

The invention relates to the technical field of intelligent household appliances, and discloses an air conditioner. The air conditioner comprises a heat exchanger and further comprises an electromagnetic heating device arranged at the set position of the outer surface of the heat exchanger and configured to be controlled to generate heat under the defrosting condition of the air conditioner to conduct temperature rise compensation on the outer surface of the heat exchanger. The electromagnetic heating device is arranged on the outer surface of the heat exchanger, the electromagnetic heating device is controlled to generate heat under the defrosting working condition to conduct temperature rise compensation on the outer surface of the heat exchanger, then direct heating on a frost layer onthe outer surface of the heat exchanger is achieved, the defrosting efficiency of the heat exchanger can be improved, and stable operation of the air conditioner is achieved; in the defrosting process, refrigerant reversing flowing is avoided, balance loss does not need to be built again, the indoor temperature can be kept stable, the temperature fluctuation of the refrigerant in the heat exchanger is small, and the indoor comfort is higher. The invention further provides a defrosting method for the air conditioner.

Description

technical field [0001] The present application relates to the technical field of smart home appliances, for example, to an air conditioner and a defrosting method thereof. Background technique [0002] When the air source heat pump is in heating mode, when the surface temperature of the heat exchanger is lower than 0°C and lower than the dew point temperature of the air, the surface of the heat exchanger will frost. The formation of the frost layer reduces the air flow through the heat exchanger, causing the heat transfer resistance between the refrigerant and the air, which deteriorates the heat transfer process of the heat exchanger, and finally causes the evaporation temperature of the unit to decrease, the heating capacity to decrease, and the performance of the fan to decrease. Adverse consequences such as attenuation have seriously plagued users' experience with air conditioners. Therefore, it is very necessary to periodically defrost the heat exchanger of the air sou...
