REFRIGERATION SYSTEM HAVING REFRIGERANT FLOW PATH FOR FLOW CONTROL
Document Type and Number:
WIPO Patent Application WO/2017/183444
Kind Code:
A1
Abstract:
This refrigeration system (90) is provided with a flow distributor (50) and a refrigerant flow path (60). The flow distributor (50) distributes the refrigerant introduced through an inlet port (52) to a plurality of outlet pipes (51a to 51d). The refrigerant flow path (60) is disposed on the upstream side of the flow distributor (50) in the refrigerant flow direction. The refrigerant flow path (60) has a first pipe (61), a second pipe (62), and a flow controlled space forming member (70). The first pipe (61) is connected to the inlet port (52). The second pipe (62) is located on the upstream side of the first pipe (61) in the refrigerant flow direction, and includes a bent portion (63). The flow controlled space forming member (70) is disposed between the first pipe (61) and the second pipe (62). The length (L1) of the first pipe (61) is in the range of four to sixty times the inner diameter (D1) of the first pipe (61). The flow path area (A0) of the flow controlled space (71) in the flow controlled space forming member (70) is two or more times the flow path area (A1) of the first pipe (61).
