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 first circuit C1 has a first loop that passes through a compressor 72 and a heat exchanger 7 to circulate a first heat medium. A second circuit C2 has a second loop that passes through a heating part 5 and the heat exchanger to circulate a second heat medium, and a third loop that passes through the heating part, a battery 6 and the heat exchanger to circulate the second heat medium. A control part has a first mode in which the first loop is made to circulate the first heat medium in the first circuit and the second loop is made to circulate the second heat medium in the second circuit, and a second mode in which the first loop is made to circulate the first heat medium in the first circuit and the third loop is made to circulate the second heat medium in the second circuit, which when a measured value by a first sensor S1 exceeds a first threshold, switches the first mode to the second mode.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回路Ｃ１は、圧縮機７２、および熱交換器７を通過して第１熱媒体を循環させる第１ループを有する。第２回路Ｃ２は、発熱部、および熱交換器を通過して第２熱媒体を循環させる第２ループと、発熱部５、バッテリ６、および熱交換器を通過して第２熱媒体を循環させる第３ループと、を有する。制御部は、第１回路で第１ループに第１熱媒体を循環させるとともに、第２回路で第２ループに第２熱媒体を循環させる第１モードと、第１回路で第１ループに第１熱媒体を循環させるとともに、第２回路で第３ループに第２熱媒体を循環させる第２モードと、を有する。第１センサＳ１における測定値が第１閾値を超えた場合に、第１モードから第２モードに切り替える。【選択図】図１
