Abstract

The invention relates to the technical field of air conditioners, and particularly provides an air conditioner, a defrosting control method thereof, a storage medium and a control device. The air conditioner comprises an outdoor heat exchanger. The control method comprises the steps that the air conditioner enters a reverse circulation defrosting mode; and on the premise of ensuring that the reverse circulation defrosting mode is always established, the path of refrigerant flowing through the outdoor heat exchanger is adjusted so that at least one part of the outdoor heat exchanger can be defrosted better relative to other parts. Through the arrangement mode, when the air conditioner is defrosted, on the premise that reverse circulation defrosting is reserved, a frost layer of the outdoor heat exchanger can be better removed; for example, on the premise of dividing the local importance of the outdoor heat exchanger, a better defrosting mechanism is configured for the local part with high importance or the highest importance; and for example, the refrigerant can flow through the local part for multiple times or the refrigerant with better heat carrying capacity can flow through the local part and the like.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner and its defrosting control method, storage medium, and control device. Background technique [0002] Air conditioners usually have a cooling mode and a heating mode. Through the circulation of the refrigerant in the circuit formed by the compressor-condenser-throttling component-evaporator-compressor, along with the phase change of the refrigerant, it can flow to the indoor space, etc. The target scene emits heat or cold so that the air in the indoor space reaches the desired temperature. For example, when the air conditioner is in heating mode, the indoor heat exchanger acts as a condenser that releases heat, and when the air conditioner is in cooling mode, the indoor heat exchanger acts as an evaporator that releases cold. During the heating process of the air conditioner in winter, the outdoor heat exchanger (such as fin heat exchanger) as an evapo...
