Title:
AIR-CONDITIONING DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/244126
Kind Code:
A1
Abstract:
This air conditioning device comprises: a first heat transfer tube that has a first refrigerant inlet into which a refrigerant flows, and a first refrigerant outlet out from which the refrigerant flows, the first heat transfer tube constituting a first refrigerant flow path connecting the first refrigerant inlet and the first refrigerant outlet; and a second heat transfer tube having a second refrigerant inlet into which a refrigerant flows, and a second refrigerant outlet out from which the refrigerant flows, the second heat transfer tube constituting a second refrigerant flow path connecting the second refrigerant inlet and the second refrigerant outlet, wherein a gas for performing heat exchange flows between the first heat transfer tube and the second heat transfer tube, the flow of the refrigerant flowing through the first refrigerant flow path is an opposing flow the flow direction of which is a direction where the direction of the flow of the refrigerant flowing into the first refrigerant inlet and flowing out from the first refrigerant outlet opposes the direction in which the gas flows, the flow of the refrigerant flowing through the second refrigerant flow path is a parallel flow and the flow direction of which is a direction where the direction of the flow of the refrigerant flowing into the second refrigerant inlet and flowing out from the second refrigerant outlet is parallel to the direction in which the gas flows.
