Abstract

The invention discloses a self-cleaning method of an air conditioner heat exchanger. The self-cleaning method of the air conditioner heat exchanger includes the steps of controlling an air conditioner to go into a self-cleaning mode; detecting the environment temperature of the heat exchanger to be cleaned and determining the target evaporation temperature of the heat exchanger to be cleaned according to the detected environment temperature; adjusting the rotary speed of a fan corresponding to the heat exchanger to be cleaned according to the target evaporation temperature of the heat exchanger to be cleaned and the actual evaporation temperature and controlling the heat exchanger to be cleaned to conduct frosting; and controlling the air conditioner to go into a defrosting mode of the heat exchanger to be cleaned after the surface of the heat exchanger to be cleaned is covered with a frost layer or ice layer. According to the self-cleaning method of the air conditioner heat exchanger, the air conditioner heat exchanger can be self-cleaned conveniently, the self-cleaning effect is good, and the cleaning efficiency is high.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a self-cleaning method for an air conditioner heat exchanger. Background technique [0002] In order to ensure sufficient heat exchange of the air conditioner, the heat exchanger fins of the general air conditioner are tightly designed into multi-layer sheets, and the gap between each sheet is only 1-2mm, and various pressure profiles or cracks are added to the air conditioner fins to increase heat transfer area. When the air conditioner is running, a large amount of air circulates through the heat exchanger to exchange heat. Various dust and impurities in the air will adhere to the heat exchanger, which not only affects the effect of the heat exchanger, but also easily breeds bacteria, which makes the air conditioner produce peculiar smell and even affects users. healthy. At this time, it is necessary to clean the heat exchanger of the air conditioner, but due to the ...
