To provide a vehicular temperature adjustment system that can suppress increase of friction losses of a rotary electric machine and a gear box.SOLUTION: A vehicular temperature adjustment system 10 comprises: a first temperature adjustment circuit 61 that performs temperature adjustments of an electrical motor 20 and a transmission 40; a second temperature adjustment circuit 62 that performs temperature adjustments of a power conversion device 50; a heat exchanger 63 the performs heat exchange between a first temperature adjustment medium and a second temperature adjustment medium; and a control device ECU. The control device ECU controls a valve device 626 on the basis of a temperature of the first temperature adjustment medium and a temperature of the second temperature adjustment medium. In the case that the temperature of the first temperature adjustment medium is higher than the temperature of the second temperature adjustment medium, the control device ECU controls the valve device 626 so that flow volumes of the second temperature adjustment medium to the heat exchanger 63 are smaller in comparison with the case that the temperature of the first temperature adjustment medium is lower than the temperature of the second temperature adjustment medium.SELECTED DRAWING: Figure 1

    【課題】回転電機及びギヤボックスのフリクションロスの増加を抑制することができる車両用温調システムを提供する。【解決手段】車両用温調システム10は、電動機20や変速装置40の温調を行う第1温調回路61と、電力変換装置50の温調を行う第2温調回路62と、第1温調媒体と第2温調媒体との間の熱交換を行う熱交換器63と、制御装置ECUとを備える。制御装置ECUは、第1温調媒体の温度と第2温調媒体の温度とに基づいて、バルブ装置626を制御し、第1温調媒体の温度が第2温調媒体の温度よりも高い場合には、第1温調媒体の温度が第2温調媒体の温度よりも低い場合に比べて、熱交換器63への第2温調媒体の流量が少なくなるようにバルブ装置626を制御する。【選択図】図1
