  • Patent number: 10744852
    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.

  • Patent number: 10744842
    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.

  • Patent number: 10710432
    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.

  • Publication number: 20110067422
    Abstract: An air-conditioning device for a vehicle includes a blower and an estimating portion. The blower is disposed in an air-conditioning case, and performs a dry control for a heat exchanger arranged in a passenger compartment of the vehicle by sending air. The blower uses one of power supplied from an external power source, power supplied from the battery having residual quantity equal to or larger than a predetermined quantity, or power supplied from an in-vehicle solar cell, while the vehicle is parked. The estimating portion estimates an approximate elimination of odor generated from the heat exchanger by starting the sending of air, and stops the blower based on the estimation.
