Abstract: A vehicular air-conditioning device includes a first water-refrigerant heat exchanger and a second water-refrigerant heat exchanger. The first water-refrigerant heat exchanger exchanges heat between a refrigerant of low-temperature and low-pressure and a heat transfer coolant to vaporize the refrigerant. The second water-refrigerant heat exchanger exchanges heat between the refrigerant of high-temperature and high-pressure and the coolant to condense the refrigerant. The coolant circulates through one of the first water-refrigerant heat exchanger and the second water-refrigerant heat exchanger, the other of the first water-refrigerant heat exchanger and the second water-refrigerant heat exchanger, a cooling path for cooling a heat generating component of a vehicle, and a heater core for heating air supplied to a vehicle interior in this order.

Abstract: An air conditioning device for a vehicle includes a first water-refrigerant heat exchanger, a second water-refrigerant heat exchanger, and a first flow rate adjusting unit. The first water-refrigerant heat exchanger exchanges heat between a refrigerant of low-temperature and low-pressure in a heat pump and an engine coolant flowing in an engine coolant path to vaporize the refrigerant. The second water-refrigerant heat exchanger exchanges heat between the refrigerant of high-temperature and high-pressure and the engine coolant to condense the refrigerant. The first flow rate adjusting unit is capable of adjusting a flow rate of the engine coolant supplied to a flow path connecting with the first water-refrigerant heat exchanger, and a flow rate of the engine coolant supplied to a flow path bypassing the first water-refrigerant heat exchanger.
