Abstract
An air conditioner for a vehicle includes a cooling water circuit and a heater. The cooling water circuit allows a cooling water to circulate between an engine and a heater core in a heating operation. The engine is a power source of the vehicle. The heater core is configured to heat air using a heat of the cooling water. The heater is located downstream of the engine and upstream of the heater core in the cooling water circuit and is configured to heat the cooling water.
Claims12
An air conditioner for a vehicle, comprising:
- a cooling water circuit that is configured to allow a cooling water to circulate therethrough via an engine and a heater core in a heating operation, the engine being a power source for the vehicle, the heater core being configured to heat air using a heat of the cooling water;
- a heater that is located downstream of the engine and upstream of the heater core in the cooling water circuit and is configured to heat the cooling water;
- and
- an output controller,
- wherein:
- the heater includes an exhaust-heat recovery device that allows the cooling water to flow therethrough while exchanging heat with an exhaust gas from the engine and that is configured to heat the cooling water by using heat of the exhaust gas and a heat source that includes a heat pump;
- the output controller is configured to adjust an output of the heat source based on an output of the exhaust-heat recovery device;
- the exhaust-heat recovery device is located downstream of the heat pump;
- and
- the heater core is located downstream of the exhaust-heat recovery device.
An air conditioner for a vehicle, the vehicle including an engine as a power source, the air conditioner is configured to perform an air conditioning for the vehicle, the air conditioner comprising:
- a cooling water circuit that is connectable to the engine and is configured to allow a cooling water to circulate therethrough;
- a heater core that is mounted to the cooling water circuit and is configured to heat an air using a heat of the cooling water;
- a heater that is located downstream of the engine and upstream of the heater core in the cooling water circuit and is configured to heat the cooling water;
- and
- an output controller, wherein:
- the heater includes an exhaust-heat recovery device that allows the cooling water to flow therethrough while exchanging heat with an exhaust gas from the engine and that is configured to heat the cooling water by using heat of the exhaust gas and a heat source that includes an electric heater and a heat storage device;
- the output controller is configured to adjust an output of the heat source based on an output of the exhaust-heat recovery device;
- the electric heater is located downstream of the exhaust-heat recovering device;
- the heater core is located downstream of the electric heater;
- and
- the exhaust-heat recovery device is located downstream of the heat storage device.
