Dust removal method and device applied to air conditioner outdoor heat exchanger

Abstract

The invention provides a dust removal method and device applied to an air conditioner outdoor heat exchanger. An outdoor unit of an air conditioner comprises the outdoor heat exchanger and an air duct system composed of a motor and vanes. The dust removal method includes the following steps that whether dust removal processing needs to be carried out on the outdoor heat exchanger is judged; when it is judged that the outdoor heat exchanger needs dust removal processing, at least the motor is controlled to rotate reversely, and when the outdoor unit works normally, the motor rotates forwards. By means of the technical scheme, the effect that the air conditioner automatically carries out dust removal on the outdoor heat exchanger is realized, a higher heat exchange efficiency of a condenser is guaranteed, and the complex operation of detaching the outdoor unit when the condenser is cleaned manually is avoided.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a dust removal method for an outdoor heat exchanger of an air conditioner and a dust removal device for an outdoor heat exchanger of an air conditioner. Background technique [0002] The outdoor unit of the air-cooled air conditioner is generally composed of a control system such as a refrigeration system, an air duct system, and a power circuit board controller. The refrigeration system is mainly composed of a condenser, pipeline components, compressors, and valves. Wind blades, net cover and other components. Among them, the heat exchange of the condenser is completed by the air provided by the fan flowing through the condenser. The condenser is generally composed of copper tubes and cooling fins attached to the surface of the copper tubes. The function of the cooling fins is to increase the heat transfer. area, improve heat transfer efficiency, since the distance bet...

AI Technical Summary

Problems solved by technology

These dust and other sundries are generally bad conductors of heat, which will affect the heat exchange effect of the condenser. In addition, dust and other sundries will also block the air from flowing through the surface of the condenser, reducing the heat exchange effect and affecting the user's experience of using the air conditioner.

At the same time, if the dust on the condenser is manually cleaned, the outdoor unit needs to be disassembled, and the operation process is cumbersome

[0003] Therefore, how to realize the automatic dust removal of the condenser by the air conditioner, ensure the high heat exchange efficiency of the condenser, and avoid the cumbersome operation of disassembling the outdoor unit when manually cleaning the condenser has become a technical problem to be solved urgently
