Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/029817
Kind Code:
A1
Abstract:
A refrigeration cycle device is provided with: a compressor (1); a flow channel switching device (2); a first heat exchanger (4) including a first heat exchange unit (4a) and a second heat exchange unit (4b); a flow channel conversion device (10); a first expansion valve (8a); and a second heat exchanger (9). The flow channel switching device is configured to switch whether refrigerant compressed by the compressor is to flow to the first heat exchanger or the second heat exchanger. The flow channel conversion device is configured to switch whether the refrigerant is to flow to the first heat exchange unit and the second heat exchange unit successively, whether the refrigerant is to flow to the first heat exchange unit and the second heat exchange unit in parallel, or whether the refrigerant is to flow to one of the first heat exchange unit and the second heat exchange unit. Thus, the flow channel conversion device can control the capacity of the first heat exchanger by switching the first heat exchange unit and the second heat exchange unit. Accordingly, the capacity of the heat exchanger can be controlled in accordance with the operation during high outside-air heating, low outside-air cooling, and low-capacity cooling/heating.
