Abstract

The invention provides an air conditioner, a defrosting method thereof and a readable storage medium. A branch comprising a refrigerant heat exchanger is additionally arranged between an outdoor heat exchanger and an air return port of a compressor, and during defrosting, a refrigerant subjected to heat exchange through the outdoor heat exchanger is subjected to secondary heat exchange through the refrigerant heat exchanger to obtain superheated air, then the superheated air flows back to the compressor, accordingly, the air suction amount of the compressor can be increased, the acting amount of the compressor is increased, the exhaust temperature of the compressor is increased, the defrosting speed of the air conditioner is increased, the technical problem that the indoor temperature seriously fluctuates due to long defrosting time of the air conditioner is solved, the indoor temperature can be kept stable during defrosting of the air conditioner, and the thermal comfort experience of users is improved.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner, a defrosting method thereof, and a readable storage medium. Background technique [0002] When the air conditioner is heating indoors, the surface of the heat exchanger of the outdoor unit will drop to a lower temperature and frost will form. When the frost layer reaches a certain thickness, it will affect the normal operation of the air conditioner. After a period of indoor heating, defrost treatment is required. The defrosting process of an air conditioner can be regarded as a process of indoor cooling and external heating. Generally, it takes a long time for an air conditioner to defrost, which will cause serious fluctuations in the indoor temperature and affect the user's thermal experience. Contents of the invention [0003] The main purpose of the present invention is to provide an air conditioner, its defrosting method, and a readable storag...
