AIR-CONDITIONING DEVICE

摘要

Provided is an air-conditioning apparatus, including: a heat source-side heat exchanger (3) including a plurality of heat transfer tubes (20) each having a flattened shape and being arranged in parallel to each other, the heat source-side heat exchanger (3) being used at least as a condenser of a refrigeration cycle; and an outdoor fan (50) for generating flows of air passing through the heat source-side heat exchanger (3) in a predetermined air velocity distribution. The heat source-side heat exchanger (3) is configured to exchange heat between the air and refrigerant flowing through the heat transfer tubes (20). The heat source-side heat exchanger (3) includes a plurality of refrigerant paths each including at least one of the plurality of heat transfer tubes (20). The plurality of refrigerant paths include: a plurality of two-phase paths for allowing gas refrigerant to flow into the plurality of two-phase paths and allowing the gas refrigerant to flow out as two-phase refrigerant; and a plurality of liquid-phase paths for allowing the two-phase refrigerant flowing out of the plurality of two-phase paths to flow into the plurality of liquid-phase paths, and to flow out as subcooled liquid refrigerant. The plurality of liquid-phase paths are arranged in a region lower in velocity of the air than a region where the plurality of two-phase paths are arranged.
