REFRIGERATION CYCLE DEVICE

To simplify a configuration, downsize a constitution and improve cooling capacity, heating capacity, and a COP.SOLUTION: A compressor 10 can execute a heating operation and a cooling operation. A receiver 30 is provided between an outdoor heat exchanger 13 and an indoor heat exchanger 23. A first variable restrictor 14 is provided between the outdoor heat exchanger 13 and the receiver 30. A second variable restrictor 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, a valve opening of the first variable restrictor 14 is controlled in accordance with a temperature and pressure detected by the first temperature pressure sensor 12, and a valve opening of the second variable restrictor 24 is controlled in accordance with a temperature and pressure detected by the second temperature pressure sensor 22.SELECTED DRAWING: Figure 1 【課題】構成を簡素化し体格を小型化すると共に、冷房能力、暖房能力、ＣＯＰを向上する。【解決手段】コンプレッサ１０は暖房運転動作と冷房運転動作を実行可能である。レシーバ３０は室外熱交換器１３と室内熱交換器２３との間に設けられる。第１可変絞り１４は室外熱交換器１３とレシーバ３０との間に設けられ、第２可変絞り２４は室内熱交換器２３とレシーバ３０との間に設けられる。第１温度圧力センサ１２はコンプレッサ１０の第１開口１１と室外熱交換器１３との間に設けられ、第２温度圧力センサ２２はコンプレッサ１０の第２開口２１と室内熱交換器２３との間に設けられる。暖房運転動作時および冷房運転動作時に第１温度圧力センサ１２で検出される温度および圧力に応じて第１可変絞り１４の弁開度が制御され、第２温度圧力センサ２２で検出される温度および圧力に応じて第２可変絞り２４の弁開度が制御される。【選択図】図１
