Abstract: A vehicle air conditioner has a compressor, a radiator, a pressure reducer, a cooling heat exchanger, a temperature detector, and a prohibition request output part. The compressor draws and discharges a refrigerant. The radiator dissipates heat of the refrigerant. The pressure reducer decompresses and expands the refrigerant. The cooling heat exchanger cools an air blown into a vehicle compartment. The temperature detector detects a temperature of the cooling heat exchanger. The prohibition request output part outputs a request, which prohibits the idle stop control, to an idle stop controller when the engine is operated. The request prohibits the idle stop control until the temperature of the cooling heat exchanger falls to a temperature being enough cool to cool the air and a required cooling time elapses. The required cooling time is estimated to be required to make a passenger feel cool by the air.

Abstract: A vehicular air-conditioning device includes a blowing port mode door as an air volume regulator that regulates volumes of air-conditioning air blown to a driver seat area, a front passenger seat area, and a rear seat area inside a vehicle compartment, and an air-conditioning controller activated by an activation signal outputted from a body controller in response to opening and closing of a rear seat door during a stoppage of a vehicle system. The air-conditioning controller is capable of operating an actuator for driving the blowing port mode door to blow the air-conditioning air to the rear seat area when an activation switch of the vehicle system is turned on in a state where the air-conditioning control unit has been activated by the activation signal.

Abstract: In a vehicle air conditioner, a controller is configured (i) to set a target cooling temperature of air cooled by a cooling heat exchanger, (ii) to control an operation of a compressor based on a cooling temperature and the target cooling temperature of the cooling heat exchanger, and (iii) to determine a traveling state of the vehicle. The controller is configured to set a normal target temperature as the target cooling temperature when the vehicle is traveling with a normal condition, and to set a modified target temperature higher than the normal target temperature as the target cooling temperature when the vehicle starts decelerating. In addition, the controller is configured to cause the compressor to stop operating when the vehicle starts decelerating, and to cause the compressor to restart operating when the cooling temperature detected by a temperature sensor is equal to or higher than the modified target temperature.

Abstract: A vehicular air conditioning device includes a blower, a heating heat exchanger, an auxiliary heater, and a blower controller. The heating heat exchanger heats blown air by exchanging heat between the blown air and the cooling water of the in-vehicle device emitting heat during operation. The blower controller is configured to control the operation of the blower. The blower controller is configured to increase a blowing capacity of the blower with increase of a temperature of the cooling water. The blower controller, during operation of the auxiliary heater, increases the blowing capacity after a waiting time during which the increase of the blowing capacity is prohibited has elapsed since a start-up switch of a vehicle system is turned on. The vehicular air conditioning is capable of implementing a quick warming of the in-vehicle device without impairing the heating feeling of occupant.
