PROBLEM TO BE SOLVED: To early secure a high-temperature heat source necessary for a desorption process in a vehicular air conditioning device including an adsorption type heat pump.SOLUTION: A vehicular air conditioning device 10 including an adsorption type heat pump includes: a first circulation circuit 40 for circulating a coolant between an engine 80 and adsorption/desorption sections (22A, 24A) on a desorption process side; an exhaust heat recovery device 82 provided in the first circulation circuit 40 leading from the engine 80 to the adsorption/desorption sections (22A, 24A) on the desorption process side to heat the coolant; and a control section for performing control so as to reduce a flow rate of the coolant caused to flow into the adsorption/desorption sections (22A, 24A) on the desorption process side when a temperature of the coolant downstream of the exhaust heat recovery device 82 does not reach a predetermined value.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、脱離工程に必要な高温熱源を早期に確保する。【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、エンジン80から脱離工程側の吸着脱離部(22A,24A)に至るまでの第1循環回路40に設けられ、冷却液を加熱するための排気熱回収器82と、排気熱回収器82の下流側の冷却液の温度が所定値に満たない場合、脱離工程側の吸着脱離部(22A,24A)に流入される冷却液の流量を減少させるように制御する制御部と、を有している。【選択図】図1
