Abstract: A heat pump and a heater core are provided at a heating coolant water circuit connected to an engine. As heating thermal amount control, the control of decreasing the output of the heat pump and increasing the output of the engine with an increase in an engine outlet water temperature detected by an engine outlet water temperature sensor, thereby ensuring a target heating thermal amount. Thus, in response to a decrease in a heat generation efficiency of the heat pump with an increase in the engine outlet water temperature, the output of the heat pump is decreased so that fuel economy can be improved while the output of the engine is increased so that the target heating thermal amount can be ensured.

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.

Abstract: An air conditioner for a vehicle including an engine, which serves as a power source and is configured to allow a cooling water to flow therethrough, includes a cooling water circuit, a heater, temperature sensors, and an output controller. The cooling water circuit allows the cooling water to circulate therein in a heating operation. The heater serves as a heat source, other than the engine, configured to heat the cooling water circulating in the cooling water circuit. The temperature sensors are connectable to the cooling water circuit and are configured to detect a temperature of the cooling water. The temperature sensors are positioned upstream and downstream of at least one of the engine and the heater. The output controller is configured to adjust at least an output of the heater based on the temperatures of the cooling water detected by the temperature sensors.

Abstract: An air conditioning device for a vehicle includes a door control unit that controls multiple blowing port doors or an air mix door to prevent a heat generated from a heater core from leaking out of an air conditioning case before air conditioning of a vehicle interior is determined to be started. The air conditioning device includes an air conditioning control unit that performs the air conditioning of the vehicle interior by controlling the multiple blowing port doors to open at least one of multiple blowing ports and blow out a heat in the air conditioning case as hot air to the vehicle interior from the at least one blowing port after the air conditioning in the vehicle interior is determined to be started.
