To provide 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 can switch a conduit line through which the second heat medium flows, between the first conduit line and the second conduit line, and a second loop that passes through either of the first conduit line and the second conduit line to circulate the second heat medium. A control part regulates a duty ratio which is a time ratio at which the valve makes the second heat medium flow through the first conduit line in a predetermined time, on the basis of a measured value by the sensor.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熱媒体が流れる管路を第1管路と第2管路との間で切り替え可能なバルブ32と、第1管路または第2管路のいずれか一方を通過して第2熱媒体を循環させる第2ループと、を有する。制御部はセンサの測定値に基づいて、バルブによって所定時間のうち第2熱媒体が第1管路を流れる時間の比率であるデューティ比を調整する。【選択図】図1
