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; an accumulator 71 that subjects the first heat medium to gas-liquid separation; a compressor 72 that compresses the first heat medium; a heat exchanger 73 for air-conditioning that performs heat-exchange between the first heat medium and air; a first expansion valve; a second expansion valve; and a heat-exchange amount regulating part 20 that regulates a heat-exchange amount in the heat exchanger for air-conditioning. The first circuit has a first loop and a first sub loop which circulate the first heat medium at the same time. The first loop passes through the accumulator, the compressor, the heat exchanger for air-conditioning and the first expansion valve in this order to circulate the first heat medium. The first sub loop passes through the accumulator, the compressor and the second expansion valve in this order to circulate the first heat medium.SELECTED DRAWING: Figure 1
