Title:
METHOD AND APPARATUS FOR SELF-CLEANING OF AIR CONDITIONER, AND AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2023/082636
Kind Code:
A1
Abstract:
A method for the self-cleaning of an air conditioner, an apparatus for the self-cleaning of an air conditioner, and an air conditioner. The method comprises: acquiring dirty blockage information of an evaporator (2); and if the dirty blockage information indicates that the evaporator (2) needs to be cleaned, controlling a two-way valve (6) to be closed, so that frost is formed on the surface of the evaporator (2). The opening/closing of a second capillary tube (5) provided in parallel to the two-way valve (6) is controlled by controlling the opening/closing of the two-way valve (6); during a normal refrigeration process of an air conditioner, refrigeration is realized by means of a refrigeration circulation loop formed by a compressor (1), the evaporator (2), a condenser (3), the two-way valve (6), and the first capillary tube (4); and when it is determined that the evaporator (2) needs to be cleaned, the two-way valve (6) is controlled to be opened, and in this case, a first capillary tube (4) and the second capillary tube (5) in the system jointly implement a throttling function to reduce evaporation pressure of a refrigeration system of the air conditioner, so that frost is formed on the surface of the evaporator (2) to clean the evaporator (2), thereby implementing the self-cleaning of the evaporator (2) without mounting an electronic expansion valve.
