VEHICULAR TEMPERATURE REGULATOR AND CONTROL METHOD OF VEHICULAR TEMPERATURE REGULATOR

To provide a vehicular temperature regulator and a control method of a vehicular temperature regulator which can enhance a heating capability of a compressor, as one embodiment of the present invention.SOLUTION: The vehicular temperature regulator comprises: a first circuit C1 through which a first heat medium flows; a compressor 72, arranged in the first circuit, which compresses the first heat medium; a heat exchanger 73 for air-conditioning, arranged in the first circuit, which performs heat-exchange between the first heat medium and air; a flow rate control valve 69 arranged in the first circuit; a sensor S2, arranged in the first circuit, which measures a temperature or pressure of the first heat medium; a second circuit C2 through which a second heat medium flows; and a first heat exchanger 7A, arranged across the first circuit and the second circuit, which performs heat-exchange between the first heat medium and the second heat medium. The first circuit has a first conduit line passing on the heat exchanger for air-conditioning and a second conduit line passing on the first heat exchanger. The flow rate regulation valve regulates a flow ratio of the first heat medium flowing through the first conduit line and the second conduit line.SELECTED DRAWING: Figure 1 【課題】圧縮機の加熱能力を高めることができる車両用温調装置および車両用温調装置の制御方法を提供する。【解決手段】第１熱媒体が流れる第１回路Ｃ１と、前記第１回路に配置され前記第１熱媒体を圧縮する圧縮機７２と、前記第１回路に配置され前記第１熱媒体と空気との間で熱交換を行う空調用熱交換器７３と、前記第１回路に配置される流量調整弁６９と、前記第１回路に配置され前記第１熱媒体の温度又は圧力を測定するセンサＳ２と、第２熱媒体が流れる第２回路Ｃ２と、前記第１回路および前記第２回路に跨って配置され前記第１熱媒体と前記第２熱媒体との間で熱交換を行う第１熱交換器７Ａとを備える。前記第１回路は、前記空調用熱交換器を通過する第１管路と、前記第１熱交換器を通過する第２管路と、有する。前記流量調整弁は、前記第１管路および前記第２管路に流れる前記第１熱媒体の流量比を調整する。【選択図】図１
