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 secured due to a low external temperature.SOLUTION: A vehicle temperature control system comprises a coolant circuit and a heat medium circuit. The heat medium circuit is configured to enable a low-pressure side circuit including a low-pressure side heat exchanger and a high-pressure side circuit including a high-pressure side heat exchanger to be arranged in a form of a parrel circuit, and is configured to enable setting a series circuit including the low-pressure side heat exchanger and the high-pressure side heat exchanger to be arranged in series. The vehicle temperature control system has a compressor heat source mode, as an operation mode to use the series circuit, which causes a heat medium discharged from the high-pressure side heat exchanger to flow into the low-pressure side heat exchanger through a temperature control unit and then return to the high-pressure side heat exchanger through an outdoor bypass passage.SELECTED DRAWING: Figure 4
【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】車両用の温調システムは、冷媒回路と熱媒体回路とを備える。熱媒体回路は、低圧側熱交換器を含む低圧側回路と、高圧側熱交換器を含む高圧側回路とを並列的に設定可能に構成されるとともに、直列に配置される低圧側熱交換器および高圧側熱交換器を含む直列回路を設定可能に構成され、温調システムは、直列回路を用いる運転モードとして、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を備える。【選択図】図4
