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 control device is provided with: a pressure acquisition unit, that acquires a detection value from a pressure sensor that detects a pressure of a refrigerant flowing through a heat, exchanger; a temperature acquisition unit that acquires a detection value from, a temperature sensor that detects a temperature of a heating medium flowing through the heat exchanger; and a determination unit that, in the case where a command is issued to cause a refrigerant to flow through an opening and closing portion in a state where the refrigerant is not flowing through, the opening and closing portion, determines whether or not the opening and closing portion is normally opened to cause the refrigerant to flow through the heat, exchanger, by using the pressure of the refrigerant detected by the pressure sensor and the temperature of the heating medium detected by the temperature sensor.

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.
