Document Type and Number:
WIPO Patent Application WO/2022/215193
Kind Code:
A1
Abstract:
This refrigeration cycle device comprises: a refrigerant circuit that is configured by a compressor, a first heat exchanger, an expansion unit, and a second heat exchanger being connected by refrigerant piping and circulates a refrigerant therethrough; and a blower that sends air to the first heat exchanger. The first heat exchanger has: a downwind side heat exchanger that has an upstream side flattened tube formed with an upstream side flow path into which the refrigerant discharged from the compressor flows, and is disposed on the downwind side of the flow of air sent from the blower; and an upwind side heat exchanger having a downstream side flattened tube that is formed with a downstream side flow path into which the refrigerant discharged from the downwind side heat exchanger flows and that has a shorter longitudinal width in the tube axial section than the upstream side flattened tube, and disposed on the upwind side of the air flow of the downwind side heat exchanger.
