Abstract

The invention discloses an air-conditioning heat exchanger self-cleaning method. The air-conditioning heat exchanger self-cleaning method includes controlling an air-conditioning to enter a self-cleaning mode; detecting a temperature of an environment in which a heat exchanger to be cleaned is located, and determining a target vaporization temperature of the heat exchanger to be cleaned according to the detected environment temperature; regulating a coolant flow rate of the heat exchanger to be cleaned according to the target vaporization temperature and an actual vaporization temperature of the heat exchanger to be cleaned, and controlling the heat exchanger to be cleaned for frosting; covering the surface of the heat exchanger to be cleaned with a frost layer or an ice layer, and controlling the air-conditioning to enter a defrosting mode of the heat exchanger to be cleaned. The air-conditioning heat exchanger self-cleaning method is capable of achieving self-cleaning of the air-conditioning heat exchanger conveniently, and is good in self-cleaning effect and high in cleaning efficiency.

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 ...
