Summary:To provide an air conditioner for a vehicle which can rise a temperature of a heater core swiftly at the time of requiring heating.SOLUTION: An air conditioner for a vehicle comprises a heater core 10, a first liquid circulation circuit 3, a second liquid circulation circuit 5, and a heat pump circuit 7. The first liquid circulation circuit 3 is configured so that heated liquid flows to the heater core 10. The second liquid circulation circuit 5 is configured so that cooled liquid flows. The heat pump circuit 7 includes a compressor 15, an expansion valve 16, a high pressure side heat exchanger 17, and a low pressure side heat exchanger 18. The low pressure side heat exchanger 18 is disposed by adjoining the second liquid circulation circuit 5 in a manner capable of thermally exchanging with the liquid flowing through the second liquid circulation circuit 5. The high pressure side heat exchanger 17 is disposed by adjoining the first liquid circulation circuit 3 in a manner capable of thermally exchanging with the liquid flowing through the first liquid circulation circuit 3, and a heat exchanging part of the high pressure side heat exchanger 17 is connected by a direct connection flow passage 60 in which another flow passage is not connected by confluence with respect to the heater core 10.SELECTED DRAWING: Figure 3 【課題】暖房必要時にヒータコアを迅速に昇温することができる車両用空調装置を提供する。【解決手段】車両用空調装置は、ヒータコア１０と、第１液体循環回路３と、第２液体循環回路５と、ヒートポンプ回路７と、を備えている。第１液体循環回路３は加熱された液体をヒータコア１０に流す。第２液体循環回路５は冷却された液体が流れる。ヒートポンプ回路７は、圧縮機１５と、膨張弁１６と、高圧側熱交換器１７と、低圧側熱交換器１８を有する。低圧側熱交換器１８は、第２液体循環回路５を流れる液体と熱交換可能に第２液体循環回路５に接して配置されている。高圧側熱交換器１７は、第１液体循環回路３を流れる液体と熱交換可能に第１液体循環回路３に接して配置されるとともに、高圧側熱交換器１７の熱交換部がヒータコア１０に対して他流路が合流接続されない直結流路６０によって接続されている。【選択図】図３
