Title:
HEAT EXCHANGER OR REFRIGERANT DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/180931
Kind Code:
A1
Abstract:
According to the present invention, a first superheating region (SH3), in which a superheated gas refrigerant flows, and a first super cooling region (SC1), in which a super-cooled liquid refrigerant flows, are formed in a windward heat exchange part (50) of an indoor heat exchanger (25) when a refrigerant introduced from a first gas-side entrance (GH1) of a first windward header (56) is discharged from a first liquid-side entrance (LH1) of a second windward header (57). A windward folding pipe (58) forms a windward folding flow passage (Jp1) which communicates the first windward header (56) and the second windward header (57). The first windward header (56) forms a first windward space (A1) and a second windward space (A2) which communicate with the first superheating region (SH3). The second windward header (57) forms: a third windward space (A3) communicating with the first windward space (A1) through a windward heat-transfer pipe (45a); and a fourth windward space (A4) communicating with the first super cooling region (SC1). The windward folding flow passage (JP1) communicates the second windward space (A2) and the third windward space (A3).
