To suppress a temperature of air flowing into a vehicle interior from varying.SOLUTION: An on-vehicle temperature regulation system 1 comprises: a low temperature circuit 3 which has a chiller 27 and through which cooling water circulates through the chiller; a heat discharging part that dissipates heat to air flowing into a vehicle interior; a refrigeration circuit in which a refrigerant circulates and which makes the refrigerant absorb heat from cooling water in the chiller and makes the refrigerant discharge heat in the heat discharging; a ratio adjustment device that adjusts a heat discharging part passing-ratio that is a ratio of flow volumes of air passing through the heat discharging part of air flowing into the vehicle interior; and a control device 5 that controls a movement heat-quantity adjustment instrument that can adjust a movement heat quantity in the refrigeration circuit and the ratio adjustment device. When it is predicted that a temperature of cooling water flowing through the chiller lowers by more than a reference value, the control device controls the movement heat-quantity adjustment instrument so that the movement heat quantity increases and controls the ratio adjustment device so that the heat discharging part passing-ratio becomes lower, before the temperature of the cooling water flowing through the chiller becomes lower by more than the reference value.SELECTED DRAWING: Figure 11
【課題】車両の室内への流入する空気の温度の変化を抑制する。【解決手段】車載温調システム1は、チラー27を有すると共にチラーを通って冷却水が循環する低温回路3と、車両の室内に流入する空気に放熱する放熱部と、冷媒が循環すると共にチラーにおいて冷却水から冷媒に吸熱させると共に放熱部において冷媒から放熱させる冷凍回路と、車両の室内に流入する空気のうち放熱部を通る空気の流量の比率である放熱部通過比率を調整する比率調整装置と、冷凍回路における移動熱量を調整可能な移動熱量調整機器及び比率調整装置を制御する制御装置5と、を有する。制御装置は、チラーを流れる冷却水の温度が基準値以上低下することが予測される場合には、チラーを流れる冷却水の温度が基準値以上低下する前に、移動熱量が多くなるように移動熱量調整機器を制御し、且つ放熱部通過比率が低くなるように比率調整装置を制御する。【選択図】図11
