To provide a vehicle temperature control system and a temperature control method capable of reliably performing heating operation even when a heat source is difficult to be secure due to a low external temperature.SOLUTION: A temperature control system comprises a coolant circuit and a heat medium circuit. The heat medium circuit includes a high-pressure side heat exchanger, a low-pressure side heat exchanger, a pump, an outdoor heat exchanger, a temperature control unit and an outdoor bypass passage. In a compressor heat source mode in which a heat medium discharged from the high-pressure side heat exchanger flows into the low-pressure side heat exchanger through the temperature control unit and returns to the high-pressure side heat exchanger through the outdoor bypass passage, a control device is adapted to control lower pressure of the coolant circuit to equal to 0.2 MPa or larger and 1.2 MPa or lower by adjusting a flow rate of the heat medium flowing in the low-pressure side heat exchanger.SELECTED DRAWING: Figure 2

    【課題】外気温が低いため熱源の確保が難しい状況であっても加熱能力を担保することが可能な車両用の温調システムおよび温調方法を提供すること。【解決手段】温調システムは、冷媒回路と、熱媒体回路とを備える。熱媒体回路は、高圧側熱交換器と、低圧側熱交換器と、ポンプと、室外熱交換器と、温調機器と、室外バイパス経路とを含む。制御装置は、高圧側熱交換器から流出した熱媒体が、温調機器を経由して低圧側熱交換器に流入し、さらに室外バイパス経路を通り、高圧側熱交換器に流入する圧縮機熱源モードにおいて、低圧側熱交換器を流れる熱媒体の流量の調整により、冷媒回路の低圧を0.2MPa以上、1.2MPa以下に制御するように構成されている。【選択図】図2
