PROBLEM TO BE SOLVED: To suppress operation of a high-temperature heat source aiming to heating inside of a cabin and improve fuel economy 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: an indoor heat exchanger 52 provided downstream of a blower: and an indoor air-conditioning unit comprising a heater core 82. The vehicular air-conditioning device also includes: a first circulation passage 40 for circulating coolant between a high-temperature heat source (engine 80) and adsorption and desorption sections (22A, 24A) on the desorption process side; a second circulation passage 90 for circulating the coolant between a heat source in an adsorption type heat pump 20, the heater core 82 and either one of the indoor heat exchanger 52 and an outdoor heat exchanger 62; and a third circulation passage 92 for circulating the coolant between evaporation and condensation sections (22B, 24B) on the adsorption process side and the other one of the indoor heat exchanger 52 and the outdoor heat exchanger 62.SELECTED DRAWING: Figure 1
