Abstract

The invention relates to a method for controlling defrosting operation of an air-conditioner; when one defrosting operation period is completed or one defrosting operation period is divided into a plurality of stages, an outdoor condensate fan is controlled to operate reversely for a certain time t at the end of each stage and blows off defrosted water on a condenser. The method for controlling defrosting operation of the air-conditioner is particularly applicable to the air-conditioner with the condenser using a micro-channel special structure; the fan of the outdoor unit is utilized sufficiently; during the defrosting operation, the condensate fan of the outdoor unit is controlled to operate reversely within a short time and blows off the defrosted water on the condenser, so that the purpose of completely defrosting is achieved; and the method is also applicable to other air conditioners with finned tube type condensers.

Description

technical field

[0001] The invention relates to an air conditioner, in particular to an air conditioner defrosting operation control method, which belongs to the technical field of air conditioners. Background technique

[0002] Air conditioners are divided into cooling-only air conditioners and heat pump air conditioners according to their functions. Cooling-only air conditioners can only perform cooling operations, while heat pump air conditioners can perform both cooling and heating operations. The refrigerant circulation system of the heat pump air conditioner is mainly composed of a compressor, a four-way valve, a condenser, a condensing fan, a throttling element, an evaporator, and an evaporating fan.

[0003] The cooling operation of the air conditioner is mainly that the high-temperature and high-pressure refrigerant gas discharged from the compressor passes through the four-way valve and enters the condenser. The refrigerant exchanges heat with the outdoor air in th...
