Summary:To perform a heat pump heating operation using a refrigeration cycle circuit even when an outside temperature is at a cryogenic temperature.SOLUTION: A temperature control system 1 is equipped with a refrigeration cycle circuit 20 and a cooling water circuit 50. The refrigeration cycle circuit 20 has an electric compressor 21 that compresses a refrigerant, a heater core 22 that heats air used for air-conditioning by using the heat of the refrigerant compressed by the electric compressor 21, and a cooling water-refrigerant heat exchanger 26 that exchanges heat between the refrigerant and cooling water in the cooling water circuit 50. The cooling water circuit 50 has an electric pump 51 sucking/discharging the cooling water, an electric hot water heater 54 that heats the cooling water, a storage battery heat exchanger 53 that exchanges heat with the storage battery 2, and a cooling water-refrigerant heat exchanger 26. When the heater core 22 performs a heating operation for heating air in the refrigeration cycle circuit 20, the electric hot water heater 54 heats the cooling water, and the cooling water-refrigerant heat exchanger 26 absorbs heat from the cooling water to the refrigerant.SELECTED DRAWING: Figure 1 【課題】外気温度が極低温であっても冷凍サイクル回路を用いたヒートポンプ暖房運転を行う。【解決手段】温度制御システム1は、冷凍サイクル回路20と冷却水回路50とを備え、冷凍サイクル回路20は、冷媒を圧縮する電動コンプレッサ21と、電動コンプレッサ21にて圧縮された冷媒の熱を用いて空調に用いられる空気を加熱するヒータコア22と、冷媒と冷却水回路50内の冷却水との間で熱交換を行う冷却水-冷媒熱交換器26と、を有し、冷却水回路50は、冷却水を吸入吐出する電動ポンプ51と、冷却水を加熱する電気温水ヒータ54と、蓄電池2と熱交換を行う蓄電池熱交換器53と、冷却水-冷媒熱交換器26と、を有し、冷凍サイクル回路20にてヒータコア22が空気を加熱する暖房運転を行うときには、電気温水ヒータ54にて冷却水を加熱して、冷却水-冷媒熱交換器26にて冷却水から冷媒に吸熱する。【選択図】図1
