To provide a temperature regulation device having a simple structure which can cool an object to be subject to temperature regulation by using a refrigeration cycle for air conditioning.SOLUTION: A refrigeration cycle 12 has a compressor 13, a refrigerant heat radiator 14, a first expansion valve 16, a first evaporator 17, a second expansion valve 20, and a second evaporator 21. In a heat medium circuit 30, a heat medium circulates flowing through an air heat exchanger 32 and the second evaporator 21. The refrigerant heat radiator 14 radiates heat from the refrigerant to outdoor air. The first evaporator 17 causes the refrigerant and front ventilation air Af to exchange heat to evaporate the refrigerant and cool the front ventilation air Af. The second evaporator 21 causes the refrigerant and the heat medium in the heat medium circuit 30 to exchange heat to evaporate the refrigerant and cool the heat medium. The air heat exchanger 32 causes the heat medium and rear ventilation air Ab to be subject to temperature regulation to exchange heat to cool the rear ventilation air Ab.SELECTED DRAWING: Figure 1 【課題】空調用の冷凍サイクルを用いて温調対象を冷却することが可能な簡素な構成の温調装置を提供する。【解決手段】冷凍サイクル１２は、圧縮機１３と冷媒放熱器１４と第１膨張弁１６と第１蒸発器１７と第２膨張弁２０と第２蒸発器２１とを有している。熱媒体回路３０では、熱媒体が空気用熱交換器３２と第２蒸発器２１とに流通しながら循環する。冷媒放熱器１４は冷媒から外気へ放熱させる。第１蒸発器１７は、冷媒と前方送風空気Ａｆとを熱交換させることにより、冷媒を蒸発させると共に前方送風空気Ａｆを冷却する。第２蒸発器２１は、冷媒と熱媒体回路３０の熱媒体とを熱交換させることにより、冷媒を蒸発させると共にその熱媒体を冷却する。そして、空気用熱交換器３２は、熱媒体と温調対象である後方送風空気Ａｂとを熱交換させることにより後方送風空気Ａｂを冷却する。【選択図】図１
