A vehicle equipped with an electric motor includes an electric motor, an electrical storage device, an air-conditioning device, a heat source cooling circuit and a controller. The air-conditioning device includes a heater core, an air conditioning hot liquid circuit that causes a thermal medium liquid to flow through the heater core, and a temperature raising device that raises a temperature of the thermal medium liquid and cause electric power consumption. When regenerative braking is performed by the electric motor when a state of charge of the electrical storage device is a predetermined value or more, the controller raises a temperature of the thermal medium liquid using the temperature raising device and switches connection and shutting between the air conditioning hot liquid circuit and the heat source cooling circuit according to a temperature of the thermal medium liquid in the air conditioning hot liquid circuit and the heat source cooling circuit.

Vehicle equipped with electric motor

An electric vehicle includes an electric motor, an electrical storage device, an air-conditioning apparatus and a controller. A coolant circuit of the air-conditioning apparatus has a compressor, an outdoor heat exchanger, an expansion valve for cooling, and an evaporator. The evaporator has a heat storage member. In a case in which regenerative braking by the electric motor is performed when the state of charge of the electrical storage device is the predetermined value or more, the controller controls the air-conditioning apparatus such that a temperature of the evaporator is decreased so as to be lower than a temperature of the evaporator when a state of charge of the electrical storage device is less than a predetermined value.

Electric vehicle

A motor-driven vehicle includes an electric motor, a power storage device, a control device, and a refrigerant circuit. The refrigerant circuit has a compressor, an indoor heat exchanger, an expansion valve, and an outdoor heat exchanger. The indoor heat exchanger exchanges heat with the refrigerant compressed by the compressor. The refrigerant which passes through the indoor heat exchanger is decompressed by the expansion valve, and the outdoor heat exchanger exchanges heat with the decompressed refrigerant and allows the refrigerant to return to the compressor. When the remaining capacity of the power storage device is equal to or more than a predetermined value, the control device operates the compressor and decreases a passing-through air volume of a first air guide device that controls a passing-through air volume of the outdoor heat exchanger.

Motor-driven vehicle

An electric vehicle includes an electric motor, a power storage device, a control device, and a refrigerant circuit. The refrigerant circuit includes a compressor, an outdoor heat exchanger, a first indoor heat exchanger, a first expansion valve, a second expansion valve, and a second indoor heat exchanger. The control device repeats an operation of performing the other of a first operation and a second operation after performing one thereof when a remaining capacity of a power storage device is equal to or larger than a predetermined value. In the first operation, the first expansion valve is not decompressed and the second expansion valve is decompressed. In the second operation, the first expansion valve is decompressed and the second expansion valve is not decompressed.

A boiler-equipped absorption heat pump unit in which a regenerator, a boiler, and other high-temperature devices are separated from an evaporator, an absorber, and other low-temperature devices are separated by an insulated dividing wall. The dividing wall reduces heat loss by impeding the transfer of heat from the high-temperature devices to the low-temperature devices.
