Document Type and Number:
WIPO Patent Application WO/2022/151762
Kind Code:
A1
Abstract:
The present invention belongs to the technical field of air conditioners. Specifically provided are a self-cleaning control method for an air conditioner, and an air conditioner. The present invention aims to solve the problem of an existing air conditioner being unable to deeply clean oil dirt. In order to achieve this aim, the self-cleaning control method of the present invention specifically comprises: controlling the temperature of a heat exchanger to be less than or equal to a frost point temperature, such that the surface thereof is frosted up; after a frosting thickness reaches a set value, controlling the temperature of the heat exchanger to rise, such that the surface thereof is defrosted; when the degree of defrosting has just reached complete melting, spraying a cleaning agent on the surface of the heat exchanger; controlling the temperature of the heat exchanger to be less than or equal to a second dew point temperature, such that dew is condensed on the surface thereof; and controlling the temperature of the heat exchanger to rise, such that the surface thereof is dried again. When the degree of defrosting has just reached complete melting, a cleaning agent is sprayed to the surface of a heat exchanger, and frost water in a dust removal mode is used, such that the time of the whole self-cleaning control method is shortened, and the energy consumption is reduced.
