PROBLEM TO BE SOLVED: To stabilize heating performance of a vehicular air conditioner comprising an adsorption type heat pump by securing a cooling liquid of water temperature needed for an evaporation/condensation part on an adsorption process side.SOLUTION: A vehicular air conditioner 10 comprising an adsorption type heat pump comprises: a first circulation circuit 40 for circulating a cooling liquid between an engine 80 and an adsorption/desorption part (22A, 24A), a third circulation circuit 92 for circulating the cooling liquid between an evaporation/condensation part (22B, 24B) on an adsorption process side and an outdoor heat exchanger 62; and a heat accumulator 82 which can accumulate heat transferred from the first circulation circuit 40 and transfer the heat to the third circulation circuit 92. Further, the vehicular air conditioner comprises a control part 30 which controls the third circulation circuit 92 to circulate the cooling liquid to the heat accumulator 82 in place of the outdoor heat exchanger 62 when the temperature outside the vehicle is lower than a predetermined temperature.SELECTED DRAWING: Figure 1
【課題】吸着式ヒートポンプを備えた車両用エアコン装置において、吸着工程側の蒸発凝縮部において必要な水温の冷却液を確保することにより、暖房性能を安定させる。【解決手段】吸着式ヒートポンプを備えた車両用エアコン装置10では、エンジン80と脱離工程側の吸着脱離部(22A,24A)との間で冷却液を循環させるための第1循環回路40と、吸着工程側の蒸発凝縮部(22B,24B)と室外熱交換器62との間で冷却液を循環させるための第3循環回路92と、第1循環回路40から伝達された熱を蓄熱し、かつ第3循環回路92に熱を伝達可能な蓄熱器82と、を備えている。そして、車両の外気温が所定の温度よりも低い場合に、第3循環回路92において、室外熱交換器62に代えて蓄熱器82に冷却液を循環させるように制御する制御部30を備えている。【選択図】図1
