Abstract: An air conditioning device for vehicle includes a first water-refrigerant heat exchanger, a second water-refrigerant heat exchanger, a first bypass passage and a second bypass passage. The first bypass passage branches at a point of a coolant passage from a cooling portion of a heating component the vehicle to the second water-refrigerant heat exchanger, and the first bypass passage is capable of being communicated with the coolant passage at an upstream side of the first water-refrigerant heat exchanger. The second bypass passage bran at a point of the coolant passage from a heater core to the first water-refrigerant heat exchanger, and the second bypass passage is capable of being communicated with the coolant passage at a downstream side of the first water-refrigerant heat exchanger. A part of the first bypass passage which includes a downstream end and a part of the second bypass passage which includes an upstream end are shared.

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.

Abstract: This vehicle air conditioner includes a first water-refrigerant heat exchanger, a second water-refrigerant heat exchanger, a heater core, a distributing unit which distributes the coolant, fed from a heat generating component of a vehicle, to a plurality of cooling path, and a junction unit which causes the coolant guided from a plurality of cooling paths to join, and feeds the coolant to the heat generating component. The first water-refrigerant heat exchanger inputs the coolant distributed by the distributing unit, through a first cooling path, and feeds the coolant to be guided to the junction unit, to a second cooling path. The second water-refrigerant heat exchanger inputs the coolant distributed by the distributing unit, through a third cooling path, and feeds the coolant to the heater core. The heater core inputs the coolant fed by the second water-refrigerant heat exchanger, and feeds the coolant to be guided to the junction unit, to a fourth cooling path.
