Defrosting control method, defrosting control device, air conditioner and computer equipment

Abstract

The invention belongs to the technical field of air conditioner control, and discloses a defrosting control method, a defrosting control device, an air conditioner and computer equipment. The air conditioner heats continuously by rising the setting temperature. On the premise of maintaining the indoor temperature set by a user unchanged, the heat additionally absorbed from the outside through a refrigerant system in a heating mode is used for defrosting a frosted part of a heat exchanger in a centralized mode through a defrosting pipeline. The air flow of a defrosting pipe is subjected to closed-loop control through a valve, so that indoor temperature fluctuation is reduced to the minimum. According to the invention, the running states of an inner fan and an outer fan of the air conditioner can be maintained without switching refrigerating/heating modes, and the purpose of defrosting is achieved without shutdown. The service life of a four-way valve is prolonged, the operation stability of the air conditioner is improved, and the air conditioner comfort is not affected. The inner fan and the outer fan are defrosted without shutdown, the indoor temperature is not changed, and the comfort of the air conditioner is guaranteed to the maximum extent. Different from a traditional defrosting mode, the four-way valve does not need to the reversed frequently, so that the service life ofthe four-way valve is prolonged.

Description

technical field [0001] The invention belongs to the technical field of air conditioning control, and in particular relates to a defrosting control method, a defrosting control device, an air conditioner and computer equipment. Background technique [0002] At present, frosting on the external unit of the air conditioner is a common problem in the heating mode of the air conditioning system. The traditional defrosting method is to switch the four-way valve to turn off the internal and external fans, so that the air conditioner operates in the cooling mode. However, the problems brought about by this method are also obvious. The switching between the two modes will directly affect the heating efficiency of the air conditioner and reduce the comfort of the air conditioner. Secondly, in actual application scenarios, the defrosting mode often needs to be turned on frequently. Frequent switching will bring a certain load to the four-way valve and shorten the service life of the ai...
