PROBLEM TO BE SOLVED: To improve heating efficiency .SOLUTION: In a vehicular adsorption type air conditioner 1, a high-temperature heating medium is circulated between a heater core 3 and an engine 2 through a heating flow passage 6. Thus, by using waste heat of the engine 2, heating in a cabin can be performed. A flow passage system 30 enables switching between a cooling mode, a first heating mode and a second heating mode. In the first heating mode, the heating medium is circulated between an adsorption portion on an adsorption process side out of adsorption portions 11, 21 or an evaporation condensation portion on a desorption process side out of evaporation condensation portions 12, 22 and an indoor heat exchanger 4 or between the adsorption portion on the adsorption process side and the evaporation condensation portion on the adsorption process side and the indoor heat exchanger 4, and adsorption heat, condensation heat or combined heat of the adsorption heat and evaporation heat is used for heating the cabin. In the second heating mode, the heating medium is circulated between the adsorption portion on the adsorption process side and the evaporation condensation portion on the desorption process side and the indoor heat exchanger 4, and the adsorption heat and the condensation heat are used for heating the cabin.SELECTED DRAWING: Figure 1
【課題】暖房効率を向上させる。【解決手段】車両用吸着式空調装置1では、暖房用流路部6を通ってヒータコア3とエンジン2との間で高温の熱媒体が循環する。これにより、エンジン2の廃熱を利用して車室の暖房を行うことができる。また、流路システム30は、冷房モードと第1暖房モードと第2暖房モードとを切替え可能とされている。第1暖房モードでは、吸着部11、21のうち吸着工程側の吸着部若しくは蒸発凝縮部12、22のうち脱離工程側の蒸発凝縮部と室内熱交換器4との間、又は、吸着工程側の吸着部及び吸着工程側の蒸発凝縮部と室内熱交換器4との間で熱媒体が循環し、吸着熱、凝縮熱又は吸着熱と蒸発熱とを合わせた熱が車室の暖房に利用される。また、第2暖房モードでは、吸着工程側の吸着部及び脱離工程側の蒸発凝縮部と室内熱交換器4との間で熱媒体が循環し、吸着熱及び凝縮熱が車室の暖房に利用される。【選択図】図1
