To efficiently execute a refrigeration cycle while suppressing temporary stopping of a heating function during heating.SOLUTION: An on-vehicle temperature control device 1 includes: a first heat circuit 4 which has a heater core 43 to be used for heating and a first heat exchanger 22 and in which a first heat medium circulates; a refrigeration circuit 2 which has a first heat exchanger for condensing refrigerant and an evaporator for evaporating the refrigerant and achieves a refrigeration cycle; and a heat medium flow passage of an internal combustion engine 52 which is communicated with the first heat circuit and in which the first heat medium 1 circulates. The first heat circuit is configured so that an outlet of the heat medium flow passage communicates with a core downstream side portion on an upstream of the first heat exchanger on a downstream of the heater core and a core upstream side portion on an upstream of the heater core on a downstream of the first heat exchanger and further has a first circulation mode control device which can switch between at least two states of a first state in which the outlet of the heat medium flow passage is communicated with the core upstream side portion and a second state in which the outlet is communicated with the core downstream side portion.SELECTED DRAWING: Figure 1 【課題】暖房中に一時的に暖房機能が停止することを抑制しつつ冷凍サイクルを効率的に実施する。【解決手段】車載温調装置１は、暖房に用いられるヒータコア４３と第１熱交換器２２とを有すると共に第１熱媒体が循環する第１熱回路４と、冷媒を凝縮させる第１熱交換器と冷媒を蒸発させる蒸発器とを有すると共に冷凍サイクルを実現する冷凍回路２と、第１熱回路に連通して第１熱媒体が流通する内燃機関５２の熱媒体流路と、を備える。第１熱回路は、熱媒体流路の出口が、ヒータコアの下流であって第１熱交換器の上流のコア下流側部分と、第１熱交換器の下流であってヒータコアの上流のコア上流側部分とに連通するように構成されると共に、熱媒体流路の出口がコア上流側部分に連通した第１状態とコア下流側部分に連通した第２状態との少なくとも二つの状態の間で切り替え可能な第１流通態様制御装置を更に備える。【選択図】図１
