Abstract

The invention relates to an anti-freezing heat exchange assembly and an air conditioning defrosting system. The anti-freezing heat exchange assembly comprises a first heat exchanger and a defrosting heat exchange tube arranged below a heat exchange tube of the first heat exchanger. Defrosting water flows downwards to the defrosting heat exchange tube in the defrosting process, and the defrosting water is prevented from being deposited at the bottom of the first heat exchanger to be frozen. The first end of the defrosting heat exchange tube communicates with a first refrigerant port of the first heat exchanger, and during defrosting, a refrigerant flows out of the first refrigerant port and enters the defrosting heat exchange tube after passing through the first heat exchanger. The defrosting water is effectively prevented from icing on the defrosting heat exchange tube, so that the situation that a unit loses efficacy due to cracking in the defrosting process of an air conditioner system is avoided.

Description

technical field

[0001] The invention relates to the field of air conditioners, in particular to an antifreeze heat exchange component and an air conditioner defrosting system. Background technique

[0002] In the air conditioning system, the heat absorption and heat release process of the refrigerant is used to realize cooling and heating. The low-temperature refrigerant entering the evaporator is likely to cause frost on the evaporator during the inhalation process. Therefore, the air-conditioning system will perform defrosting treatment after running for a period of time to melt the frost formed on the evaporator, so that the heat exchange efficiency of the air-conditioning system can be maintained at a relatively high level. However, after the general air conditioning system defrosts, it is easy to crack the heat exchange tube and cause the unit to fail. Contents of the invention

[0003] Based on this, it is necessary to provide an anti-freezing heat exchange componen...
