Problems solved by technology

[0002] When the air conditioner is running in the heating mode, if the evaporation temperature of the refrigerant in the heat exchanger of the outdoor unit is low, frost may form on the heat exchanger of the outdoor unit, which will affect the heat exchange effect of the heat exchanger of the outdoor unit and affect The heating capacity and heating effect of the air conditioner, and when the frost layer reaches a certain thickness, it is necessary to turn the air conditioner to cooling operation to defrost. At this time, the air conditioner blows cold air, which further cools the room and affects the user's comfortable experience.

Abstract

The invention provides an air conditioning system and an air conditioner frosting control method. The air conditioning system includes a first adjustable throttling device, a second adjustable throttling device, a compressor, an outdoor heat exchanger and an indoor heat exchanger. The first adjustable throttling device is arranged between the outdoor heat exchanger and the indoor heat exchanger, and the second adjustable throttling device is arranged between the outdoor heat exchanger and an air return port of the compressor. By means of the air conditioning system and the air conditioner frosting control method, the effect of preventing frosting or delaying frosting can be achieved.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an air conditioning system and an air conditioning frosting control method. Background technique [0002] When the air conditioner is running in the heating mode, if the evaporation temperature of the refrigerant in the heat exchanger of the outdoor unit is low, frost may form on the heat exchanger of the outdoor unit, which will affect the heat exchange effect of the heat exchanger of the outdoor unit and affect The heating capacity and heating effect of the air conditioner, and when the frost layer reaches a certain thickness, it is necessary to turn the air conditioner to cooling operation to defrost. At this time, the air conditioner blows out cold air, which further cools the room and affects the user's comfortable experience. [0003] Therefore, how to delay or prevent the frosting of the heat exchanger of the outdoor unit has become a technical problem to be solve...
