Summary:To provide an air conditioning system capable of setting an intermediate temperature when temperature of air in a cabin is controlled by one heat exchanger for temperature conditioning, and reducing a refrigerant charging amount through downsizing of a refrigerant cycle.SOLUTION: An air conditioning system comprises a refrigerant cycle 20, a hot water cycle 30, and a cold water cycle 40, and further includes: a hot water supply bypass passage 50 for connecting a hot water side branch point 34 of the hot water cycle 30 with a hot water-cold water confluence point 43 of the cold water cycle 40; an outflow water recovery bypass passage 60 for connecting between an outflow water branch point 44 provided on a conditioned water outflow part side 11b of a temperature conditioning heat exchanger 11 in the cold water cycle 40, and a hot water side confluence point 35 provided between the hot water side branch point 34 and a cabin outside heat exchanger 32 in the hot water cycle 30; a hot water side control unit 71 capable of opening/closing between the hot water side branch point 34 and the hot water side confluence point 35; and flow rate ratio adjusting means for adjusting a flow rate ratio of hot water and cold water flowing into the temperature conditioning heat exchanger 11.SELECTED DRAWING: Figure 1 【課題】１つの温度調和用熱交換器で車室内空気を温調する場合に、中間温度の設定を可能とし、また、冷媒サイクルを小型にして冷媒充填量を少なくする空気調和システムを提供する。【解決手段】冷媒サイクル２０、温水サイクル３０、冷水サイクル４０を備え、温水サイクル３０の温水側分岐点３４と、冷水サイクル４０の温水冷水合流点４３とを接続する温水供給バイパス通路５０と、冷水サイクル４０のうち温度調和用熱交換器１１の調和水流出部１１ｂ側に設けられた流出水分岐点４４と、温水サイクル３０のうち温水側分岐点３４と車室外熱交換器３２との間に設けられた温水側合流点３５との間を接続する流出水回収バイパス通路６０と、温水側分岐点３４と温水側合流点３５との間を開閉可能な温水側制御部７１と、温度調和用熱交換器１１へ流入する温水と冷水との流量比を調整する流量比調整手段と、を有する。【選択図】 図１
