LIQUID STORAGE DEVICE, METHOD OF MANUFACTURING LIQUID STORAGE DEVICE AND AIR-CONDITIONING REFRIGERATION SYSTEM

摘要

Disclosed is a liquid storage device, comprising a first vessel body (4) and a second vessel body (3). The first vessel body (4) is a barrel-shaped structure with an opening facing the second vessel body (3). The end of the second vessel body (3) facing the first vessel body (4) is an open structure and a first connecting port (31) and a second connecting port (32) are provided at the other end of the second vessel body (3) facing away from the first vessel body (4). The liquid storage device further comprises a filter cartridge (33). The filter cartridge (33) comprises a first mating part (332), a second mating part (333) and a filter part (331) located in the middle section. The first mating part (332) mates with an inner wall of the second vessel body (3), and a space providing circulation of a refrigerant is disposed between the filter part (331) and the inner wall of the second vessel body (3). The second mating part (333) is connected with the second connecting port (32). The space between the filter part (331) and the inner wall of the second vessel body (3) is in communication with the first connecting port (31). The inside of the filter part (331) is in communication with the second connecting port (32) via the second mating part (333). The refrigerant, in the process of flowing between the first connecting port (31) and the second connecting port (32), is filtered at least once and during filtering the flow resistance is relatively low.
