PROBLEM TO BE SOLVED: To improve heating efficiency.SOLUTION: In a vehicular air conditioner 10, when a heating request is made, a first adsorption core 22C or a second adsorption core 24C on a desorption process side is connected to a first circulation circuit 40, and a first evaporation condensation core 22D or a second evaporation condensation core 24D on the desorption process side is connected to a second circulation circuit 50. Thus, cooling water in the second circulation circuit 50 warmed by using condensation heat of a refrigerant generated in the desorption process can be supplied to an indoor heat exchanger 52. Due to this configuration, during heating, the condensation heat can be used as an auxiliary heat source. That is, during heating, in addition to an engine 42 (high-temperature heat source), the condensation heat can be used as the auxiliary heat source. Therefore, heating efficiency in the vehicular air conditioner 10 can be improved.SELECTED DRAWING: Figure 1
【課題】暖房効率を向上する。【解決手段】車両用エアコン装置10では、暖房要求時に、脱離工程側の第1吸着コア22C又は第2吸着コア24Cが第1循環回路40に接続され、脱離工程側の第1蒸発凝縮コア22D又は第2蒸発凝縮コア24Dが第2循環回路50に接続される。このため、脱離工程時に発生する冷媒の凝縮熱によって温められた第2循環回路50内の冷却水を室内熱交換器52に供給することができる。これにより、暖房時において、当該凝縮熱を補助熱源として活用することができる。すなわち、暖房時において、エンジン42(高温熱源)に加えて凝縮熱を補助熱源として活用することができる。したがって、車両用エアコン装置10における暖房効率を向上することができる。【選択図】図1
