REFRIGERATION CYCLE DEVICE

WIPO Patent Application WO/2023/140249

A1

A compressor (10) is capable of heating operation and cooling operation. A receiver (30) is provided between an outdoor heat exchanger (13) and an indoor heat exchanger (23). A first variable throttle (14) is provided between the outdoor heat exchanger (13) and the receiver (30). A second variable throttle (24) is provided between the indoor heat exchanger (23) and the receiver (30). A first temperature pressure sensor (12) is provided between a first opening (11) of the compressor (10) and the outdoor heat exchanger (13). A second temperature pressure sensor (22) is provided between a second opening (21) of the compressor (10) and the indoor heat exchanger (23). During the heating operation and the cooling operation, the valve opening of the first variable throttle (14) is controlled according to the temperature and pressure detected by the first temperature pressure sensor (12), and the valve opening of the second variable throttle (24) is controlled according to the temperature and pressure detected by the second temperature pressure sensor (22).
