TEMPERATURE CONTROL SYSTEM FOR VEHICLE AND TEMPERATURE CONTROL METHOD FOR VEHICLE

To perform rapid cooling/rapid heating without restriction by a rotation frequency of a compressor with respect to temperature control of a vehicle.SOLUTION: A temperature control system for vehicle includes a refrigerant circuit and a heating medium circuit. A temperature control heat exchanger provided for the heating medium circuit is provided with a plurality of heat exchangers. The temperature control system is provided with a rapid cooling mode which includes: a second cooling mode in which a heating medium flowed out of a low pressure side heat exchanger is supplied for the plurality of heat exchangers of a temperature control heat exchanger when used for cooling; and a first cooling mode in which a heating medium flowed out of the low pressure side heat exchanger is supplied for a part of the temperature control heat exchanger prior to the second cooling mode. The temperature control system is provided with a rapid heating mode which includes: a second heating mode in which a heating medium flowed out of a high pressure side heat exchanger is supplied for a plurality of heat exchangers of the temperature control heat exchanger when used for heating; and a first heating mode in which the heating medium flowed out of the high pressure side heat exchanger is supplied for a part of the temperature control heat exchanger prior to the second heating mode.SELECTED DRAWING: Figure 3 【課題】車両用温調について、圧縮機の回転数の制約によらず、急速冷房・急速暖房を実現する。【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。熱媒体回路に備わる温調熱交換器は、複数の熱交換器を備える。温調システムは、冷却用途のとき、低圧側熱交換器を流出した熱媒体が温調熱交換器の複数の熱交換器に供給される第２冷却モードと、第２冷却モードに先行して、低圧側熱交換器を流出した熱媒体が温調熱交換器の一部の熱交換器に供給される第１冷却モードと、を含む急速冷却モードを備える。温調システムは、加熱用途のとき、高圧側熱交換器を流出した熱媒体が温調熱交換器の複数の熱交換器に供給される第２加熱モードと、第２加熱モードに先行して、高圧側熱交換器を流出した熱媒体が温調熱交換器の一部の熱交換器に供給される第１加熱モードと、を含む急速加熱モードを備える。【選択図】図３
