REFRIGERATION CYCLE DEVICE

A refrigeration cycle apparatus includes a refrigerant circuit in which at least a compressor, a condenser, a first pressure reducer, and an evaporator are connected by pipes. The condenser includes a plurality of heat transfer tubes extending in an up-and-down direction, a first header having a tubular outer wall into which first ends of the plurality of heat transfer tubes are inserted, and a partition plate that is provided from a first end to a second end of the first header in a longitudinal direction, partitions an internal space of the first header into a high-pressure refrigerant passage where the first ends of the plurality of heat transfer tubes are disposed and a low-pressure refrigerant passage where the first ends of the plurality of heat transfer tubes are not disposed, and is configured to exchange heat between high-pressure refrigerant flowing through the high-pressure refrigerant passage and low-pressure refrigerant flowing through the low-pressure refrigerant passage in the first header.
