Self-cleaning control method for air conditioner outdoor unit

Abstract

The invention relates to the technical field of air conditioners, in particular to a self-cleaning control method for an air conditioner outdoor unit. The method comprises the steps of controlling anair conditioner to enter a heating mode; in the heating mode, controlling the operation frequency of a compressor, and enabling an outdoor heat exchanger to be frosted; and when the temperature of theoutdoor heat exchanger is lower than a first preset temperature and lasts for a first preset time, conducting defrosting operation. According to the self-cleaning control method for the air conditioner outdoor unit provided by the invention, on the basis of a traditional air conditioner, redundant parts do not need to be added, the outdoor heat exchanger is subjected to the frosting-defrosting process, a water flow formed in the defrosting process flushes the surface of the outdoor heat exchanger, and impurities and bacteria attached to the surface of the outdoor heat exchanger are taken away, so that a self-cleaning effect of the outdoor heat exchanger is achieved; and in addition, different defrosting operations are selected according to the current outdoor environment temperature, so that the self-cleaning control method for the air conditioner outdoor unit is more flexible to use and beneficial to reducing energy consumption.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a self-cleaning control method for an outdoor unit of an air conditioner. Background technique [0002] When the air conditioner is running for a long time, there will inevitably be impurities and bacteria on the outdoor heat exchanger. These impurities will adhere to the outdoor heat exchanger. On the one hand, it will reduce the heat transfer performance of the heat exchanger, resulting in a decrease in the performance of the air conditioner, which will affect the use of users. experience. Contents of the invention [0003] The purpose of the present invention is to provide a self-cleaning control method for the outdoor unit of the air conditioner, which realizes the self-cleaning of the outdoor unit of the air conditioner and removes impurities attached to the surface of the outdoor heat exchanger without adding parts. [0004] In order to achieve the above object,...
