Abstract

The invention provides a defrosting control method, device, air conditioner and computer-readable storage medium, wherein the defrosting control method includes: obtaining the pressure value at the air outlet of the indoor fan; controlling the indoor heat exchanger according to the pressure value Defrost or end defrost. Through the technical scheme of the present invention, it is possible to more accurately control the indoor heat exchanger to defrost or end the defrost, improve the timeliness of defrosting and anti-freezing protection, reduce misjudgment of defrosting and anti-freezing protection, delay execution or even The phenomenon of non-execution effectively improves the cooling effect of the air conditioner, thereby improving user experience.

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 computer-readable storage medium. Background technique [0002] In the related art, when the air conditioner is running in cooling mode or dehumidification mode, it usually determines whether to perform defrosting or exit defrosting by judging the temperature of the evaporator, that is, to enter anti-freezing protection or exit anti-freezing protection, and there are the following technical defects: [0003] (1) In the working condition of the indoor heat exchanger with frost, that is, the freezing condition, the air conditioner may have a bias flow or the temperature sensor of the indoor unit of the air conditioner may be faulty, resulting in distortion of the evaporator temperature judgment, resulting in defrosting or exiting defrosting and entering The judgment accuracy of anti-...
