Abstract (en)

[origin: EP3499142A1] A refrigeration cycle apparatus includes a compressor (1), a flow path switching device (2), a first heat exchanger (4) having a first heat exchange unit (4a) and a second heat exchange unit (4b), a flow path changing device (10), a first expansion valve (8a), and a second heat exchanger (9). The flow path switching device is configured to switch flow of the refrigerant compressed by the compressor between flow to the first heat exchanger and flow to the second heat exchanger. The flow path changing device is configured to switch flow of the refrigerant among flow successively through the first heat exchange unit and the second heat exchange unit, flow in parallel through the first heat exchange unit and the second heat exchange unit, and flow through any one of the first heat exchange unit and the second heat exchange unit. This allows the flow path changing device to switch between the first heat exchange unit and the second heat exchange unit, controlling the capacity of the first heat exchanger. Thus, the capacity of the heat exchanger can be controlled in accordance with the operation during high-outside-temperature heating, low-outside-temperature cooling, and low-capacity cooling/heating.
