To make it possible to adjust temperature by changing the temperature of a heat medium in accordance with the thermal load situation of a temperature adjustment object without complicating the structure of a heat medium circuit.SOLUTION: A temperature adjustment device includes a compressor, a first heat exchange part functioning as a radiator, a decompression device, and a second heat exchange part functioning as a heat sink. The temperature adjustment device has a refrigerant circuit which circulates coolant discharged by the compressor in the first heat exchange part, the decompression device, and the second heat exchange part in this order, a heat medium circuit on a high temperature side where a heat medium heat exchanging with coolant in the first heat exchange part circulates, and a heat medium circuit on a low temperature side where the heat medium exchanging heat with the coolant in the second heat medium circuit circulates, and adjusts the temperature of a plurality of temperature adjustment objects via the heat medium. The first heat exchange part and the second heat exchange part are provided with a plurality of heat exchange elements. The heat medium circuit has a switch part which is capable of switching a serial mode in which the heat medium continuously passes the heat exchange element selected from a plurality of heat exchange elements and exchanges heat with the temperature adjustment objects, and a parallel mode in which the heat medium individually passes the heat exchange elements and exchanges heat with the temperature adjustment objects.SELECTED DRAWING: Figure 1
【課題】熱媒体回路の構成を煩雑にすること無く、温調対象物の熱負荷状況に応じて熱媒体の温度を変えて温調できるようにする。【解決手段】温調装置は、圧縮機、放熱器として機能する第1熱交換部、減圧装置、吸熱器として機能する第2熱交換部を具備し、圧縮機から吐出した冷媒を、第1熱交換部、減圧装置、第2熱交換部の順に循環させる冷媒回路と、第1熱交換部にて冷媒と熱交換した熱媒体が循環する高温側の熱媒体回路と第2熱交換部にて冷媒と熱交換した熱媒体が循環する低温側の熱媒体回路を有し、熱媒体を介して複数の温調対象の温度調整を行うものであり、第1熱交換部と第2熱交換部は、それぞれ複数の熱交換要素を備え、熱媒体回路は、熱媒体が複数の熱交換要素のうち選択した熱交換要素を連続して通過して温調対象と熱交換する直列モードと、熱媒体が熱交換要素を個別に通過して温調対象と熱交換する並列モードとを切り替え可能な切替部を有する。【選択図】図1
