Title:
HEAT EXCHANGER AND REFRIGERATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/180932
Kind Code:
A1
Abstract:
This indoor heat exchanger (25) is provided with an upwind heat exchange unit (50) in which a first gas-side port (GH1) is formed, a downwind heat exchange unit (60) in which a second gas-side port (GH2) is formed, and a connection tube (70) which forms a connection flow path (RP). The upwind heat exchange unit (50) includes an upwind first header (56), an upwind second header (57) and heat transfer tubes (45), and the downwind heat exchange unit (60) includes a downwind first header (66), a downwind second header (67) and heat transfer tubes (45). During heating operation, in the upwind heat exchange unit (50), a super cooling region (SC1, SC2), an "upwind, outlet-side space" (the upwind sixth space (A6)) communicating with a liquid-side port (LH), and an "upwind, upstream-side space" (the upwind third space (A3)) upstream of the "upwind, outlet-side space" in the refrigerant flow are formed. The connection flow path (RP) allows communication between the "downwind, downstream-side space" (the downwind second header space (Sb2) furthest downstream in the refrigerant flow in the downwind heat exchange unit (60)) and the "upwind, upstream-side space".
