Automatic cleaning treatment method and automatic cleaning treatment system of air-conditioning heat exchanger

Abstract

The invention discloses an automatic cleaning treatment method and an automatic cleaning treatment system of an air-conditioning heat exchanger. The automatic cleaning treatment method comprises the following steps: after an air-conditioner is started, judging whether the starting condition of automatic cleaning treatment of the air-conditioning heat exchanger is met; if yes, starting the refrigerating mode of the air-conditioner to enable surface of the heat exchanger to frost, and judging whether frosting is finished; after the frosting is finished, controlling the refrigerating mode of the air-conditioner to turn off, starting the air supply mode, then, starting an indoor draught fan to enable frost on the surface of the indoor heat exchanger to melt to water, and judging whether defrosting is finished; and after the defrosting is finished, controlling the heating mode of the air-conditioner to start, drying the heat exchanger, and ending cleaning. According to the invention, the inner side heat exchanger frosts after the temperature is rapidly decreased and covers and wraps dust and germs during frosting, the dust and germs on the heat exchangers are rapidly discharged along with water flow of a large quantity of defrosting water generated during the defrosting process, and automatic cleaning is realized through redrying treatment.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an automatic cleaning treatment method and system for heat exchangers of air conditioners. Background technique [0002] At present, our users have very little awareness of air conditioner maintenance. After the air conditioner is installed and in use, it is basically not necessary to do related cleaning or maintenance. However, after our air conditioner is placed or used for a long time, it is easy to damage the air conditioner. A large amount of dust has accumulated on the heat exchanger and its heat exchanger. However, if these dusts are not cleaned in time, they will adhere to the heat exchanger of the indoor unit for a long time. , because the interior space of the air conditioner is relatively airtight, the heat exchanger with dust attached to it is easy to breed bacteria and form mildew spots under long-term unventilated conditions. These bacteria and mildew spot...
