  • Patent number: 11292363
    Abstract: A charging system is installed outside an electric vehicle to charge an in-vehicle battery mounted in the electric vehicle. The charging system includes a charger that supplies electricity to the in-vehicle battery, an external cooling device that cools the in-vehicle battery, and an off-vehicle controller that controls driving of the charger and the external cooling device. The external cooling device has an external channel which is provided inside the charging system and through which an external refrigerant flows, cooling mechanisms that include at least a compressor and cool the external refrigerant, and a heat exchanger that exchanges heat between the cooled external refrigerant and an internal refrigerant that flows inside the electric vehicle to cool the in-vehicle battery or outside air that is sent to the electric vehicle to cool the in-vehicle battery.

  • Patent number: 7172018
    Abstract: A vehicle air-conditioning system improves a passenger's sensation of cooling by preventing air blown from a foot opening when a cooling load is low, creating a comfortable temperature distribution along the passenger's body. The vehicle air-conditioning system automatically selects a face mode when a target air temperature (TAO) is between a first predetermined temperature and a second predetermined temperature, which is higher than the first predetermined temperature, a bi-level mode when the TAO is higher than the first predetermined temperature and an evaporator air temperature is higher than a predetermined temperature, or a face mode when the TAO is lower than the first predetermined temperature and the evaporator air temperature is lower than the predetermined temperature.

  • Patent number: 6135201
    Abstract: In an air conditioning apparatus for a vehicle, a double layer flow mode is set when the maximum heating state is set during an air outlet mode where both a foot opening portion and a defroster opening portion are opened. During the double layer flow mode, an air passage of an air conditioning case is partitioned into a first air passage through which inside air flows and a second air passage through which outside air flows, in such a manner that the first air passage communicates with the foot opening portion and the second air passage communicates with the defroster opening portion. When the double layer flow mode is set, the maximum rotation speed of a blower for blowing air is reduced by a predetermined level as compared with an entire outside air mode or an entire inside air mode. Thus, heating capacity for a passenger compartment of the vehicle can be improved.

  • Patent number: 6073456
    Abstract: An air-conditioning device includes a control system for saving fuel consumed to drive the device and for enhancing comfortability of passengers at the same time. The air-conditioning device is operated under a cooling mode emphasizing comfortability or under an economy mode emphasizing fuel economy. Under the cooling mode, the device is controlled in a lower temperature range. Under the economy mode, the device is controlled in an intermediate temperature range to secure comfortability when cooling-down is required, and in a higher temperature range to save fuel after the cooling-down has been completed. Information on vehicle speed may be used in the control under the economy mode. The device may be turned off or controlled in a higher temperature range to save fuel, especially when the vehicle comes to a halt.

  • Patent number: 5987905
    Abstract: An air conditioning apparatus for a vehicle includes an air conditioning case for forming an air passage through which air is blown into a passenger compartment. In the air conditioning apparatus, during a cooling mode for cooling a passenger compartment, an inside/outside air introduction mode is switched from an inside/outside air-mixing mode where both inside air and outside air are introduced into the air conditioning case to an entire outside air mode where only outside air is introduced into the air conditioning case, when an engine of the vehicle is stopped and the cooling load is smaller than a predetermined cooling load. Therefore, air-suction noise from an inside air introduction port is not caused, and the air-suction noise is not noted by a passenger in the passenger compartment even when the engine is stopped. Thus, noise of the air conditioning apparatus in the passenger compartment can be reduced.

  • Patent number: 5980379
    Abstract: A defroster nozzle is provided inside an instrument panel below a front glass plate, and its length in the direction of vehicle width is gradually increased from a suck-in opening to a blow-out opening. The suck-in opening is connected to an air conditioning unit, and has a bent portion at the middle thereof. The inside of the defroster nozzle is divided by partition walls into a central chamber and side chambers. The length of the central chamber as viewed in the direction of vehicle width is gradually increased from the suck-in opening to the blow-out opening, and the opening areas of the suck-in opening and the blow-out opening of the central chamber are equal to each other. The central portion of the side wall of each of the side chambers has a bent portion.
