Title:
HEAT EXCHANGER, REFRIGERATION CIRCULATION SYSTEM, AND AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2023/040283
Kind Code:
A1
Abstract:
The present application relates to the technical field of air conditioning. Disclosed is a heat exchanger, comprising: a heat exchanger body having two refrigerant intake and output ports and a plurality of heat exchange branches; a refrigerant distribution and storage device having a confluence pipe port and a plurality of refrigerant distribution ports; and a one-way communication device which is located between the refrigerant intake and output port and the confluence pipe port and is in communication therewith, wherein a circulation direction of the one-way communication device is limited to being in communication when the heat exchanger is used as an evaporator, and to being blocked when the heat exchanger is used as a condenser. The refrigerant distribution and storage device is configured to distribute the refrigerant delivered by the refrigerant intake and output port into the plurality of heat exchange branches when the heat exchanger is used as the evaporator, and to converge and store the refrigerant when the heat exchanger is used as the condenser. According to the heat exchanger provided by the embodiments of the present disclosure, through the cooperation of the refrigerant distribution and storage device and the one-way communication device, part of the refrigerant can be stored by using the refrigerant distribution and storage device, so that the heat exchanger can also have a certain refrigerant storage function. Further disclosed in the present application are a refrigeration circulation system and an air conditioner.
