Title:
HEAT EXCHANGING DEVICE AND AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2022/089661
Kind Code:
A1
Abstract:
A heat exchanging device, comprising a first heat exchange passage (100), a second heat exchange passage (200), a flow division passage (400), a third heat exchange passage (300), a first one-way valve (500), and a second one-way valve (600). The first heat exchange passage (100) comprises at least two heat exchange branches that are connected in parallel; the second heat exchange passage (200) is connected in parallel to the first heat exchange passage (100); the second heat exchange passage (200) comprises a first pipe segment (210) and a second pipe segment (220) that are connected in series; the flow division passage (400) is connected in series to the second pipe segment (220); the third heat exchange passage (300) is connected in parallel to the second pipe segment (220) and the flow division passage (400); the first one-way valve (500) is disposed on the first pipe segment (210) of the second heat exchange passage (200); and the second one-way valve (600) is disposed on the flow division passage (400). During cooling operation, a refrigerant passes through the first heat exchange passage (100), the second pipe segment (220), and the third heat exchange passage (300) in sequence to achieve condensation and supercooling. During heating operation, the refrigerant passes through the first heat exchange passage (100), the second pipe segment (220), and the third heat exchange passage (300) in a divided manner, thereby effectively reducing pressure loss.
