VEHICULAR TEMPERATURE REGULATOR AND CONTROL METHOD FOR 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: A 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 sensor S1, 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 heat exchanger 7, arranged across the first circuit and the second circuit, which performs heat exchange between the first heat medium and the second heat medium. The second circuit has a first conduit line 12 passing on the heat exchanger, a second conduit line 13 bypassing the heat exchanger, a valve 32 that regulates a flow ratio which is a ratio of a flow rate of the second heat medium flowing through the first conduit line to a flow rate of the second heat medium flowing through the second conduit line, and a second loop passing through either of the first conduit line and the second conduit line to circulate the second heat medium. A control part makes the valve regulate the flow ratio, on the basis of a measured value by the sensor S1.SELECTED DRAWING: Figure 1 【課題】本発明の一つの態様は、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の提供を目的の一つとする。【解決手段】第１熱媒体が流れる第１回路Ｃ１と、第１回路に配置され第１熱媒体を圧縮する圧縮機７２と、第１回路に配置され第１熱媒体の温度又は圧力を測定するセンサＳ１と、第２熱媒体が流れる第２回路Ｃ２と、第１回路および第２回路に跨って配置され第１熱媒体と第２熱媒体との間で熱交換を行う熱交換器７とを備える。第２回路は、熱交換器を通過する第１管路１２と、熱交換器を迂回する第２管路１３と、第２管路を流れる第２熱媒体の流量に対する、第１管路を流れる第２熱媒体の流量の比率である流量比を調整するバルブ３２と、第１管路又は第２管路の少なくとも一方を通過して第２熱媒体を循環させる第２ループと、を有する。制御部は、センサＳ１の測定値に基づいて、バルブによって流量比を調整する。【選択図】図１
