Abstract

The invention relates to the technical field of defrosting, in particular to a defrosting control method and device of an air conditioner and the air conditioner. According to the scheme, when the airconditioner works, different environmental temperature intervals are divided according to outer loop temperature and air humidity, so as to cover all the temperature ranges of unit operation; whetherdefrosting conditions are met or not is judged according to the outer loop temperature and air humidity; and a defrosting actions corresponding to each environmental temperature interval is executedaccording to the environmental temperature interval. Accurate defrosting is achieved, frequent defrosting is prevented, an outdoor heat exchanger is divided into a first heat exchanger unit and a second heat exchanger unit during defrosting, and the two units perform defrosting alternately, so that the air conditioner can operate efficiently without frost while requirements on defrosting and customer comfort are met.

Description

technical field [0001] The invention relates to the technical field of defrosting, in particular to an air conditioner defrosting control method and device and an air conditioner. Background technique [0002] For air conditioners operating in humid and cold areas, frosting often occurs on the outdoor heat exchanger. The existence of the frost layer increases the heat exchange heat resistance and air flow resistance of the evaporator, which reduces the performance coefficient of the unit, increases the operating energy consumption, and even causes the unit to fail. In order to ensure the continuous and efficient operation of the heat pump air conditioner, periodic defrosting is required. The traditional four-way reversing valve reverse defrosting technology has problems such as high energy consumption, low efficiency, and frequent start-stop defrosting of the unit. Contents of the invention [0003] The problem to be solved by the present invention is to provide an air c...
