  • Patent number: 10639961
    Abstract: A system and method of selecting air intake between 100% fresh air mode and 100% recirculated air mode for optimum heating/cooling performance, fuel economy and/or high voltage (HV) battery power consumption is disclosed. The system and method includes a partial recirculation control strategy in which the air inlet door is moved progressively to any position by taking into account cooling/heating loads and cabin fogging probability. As cooling/heating loads increase the air inlet door moves toward 100% recirculation mode. As fogging probability increases the air inlet door moves toward 100% fresh air mode. By selectively choosing a position between 100% recirculation and 100% fresh air, fuel economy and/or HV battery power consumption is optimized without compromising passenger comfort or causing fogging on interior glass surfaces. In cooling applications the compressor load is minimized and air conditioning performance is improved due to the reduced evaporator cooling load.

  • Patent number: 8939823
    Abstract: A blower unit for a vehicle HVAC system, which is operable in one of a fresh air mode, a recirculation air mode and a mixture mode, comprises a housing defining an exterior fresh air intake aperture and an interior recirculation air intake aperture. A suction passage is in communication with both the exterior and interior air intake apertures. A first door is operably associated with the exterior air intake aperture for selectively opening and closing the exterior air intake aperture. A second door operably associated with the interior air intake aperture for selectively opening and closing the interior air intake aperture. The first and second doors are movable independent of each other. A partition is located in the suction passage for at least partially dividing the suction passage. The partition is selectively engaged by at least one of the first and second doors depending on the mode of the HVAC system.

  • Publication number: 20150017900
    Abstract: The present invention provides a windowpane defogging device for a motor vehicle which, upon generation of a fog on a windowpane, comes into a defogging mode to remove the fog generated on the windowpane. The windowpane defogging device includes a relative humidity detecting unit configured to detect a windowpane relative humidity of a driver seat view field region of the windowpane and a windowpane relative humidity of a passenger seat view field region of the windowpane, and a control unit configured to control entry into the defogging mode by determining the generation or non-generation of the fog on the windowpane based on the windowpane relative humidity of the driver seat view field region and the windowpane relative humidity of the passenger seat view field region inputted from the relative humidity detecting unit.

  • Patent number: 8932119
    Abstract: A vehicle air conditioner that can perform air conditioning operation in an inside air circulating mode while suppressing the mist on a windshield and prevent deterioration in an inside air quality. When exhaust gas concentration on the outside of a vehicle is high, an outside air lead-in mode is switched to an inside air circulating mode and window mist limit humidity at that point is calculated. When inside humidity is close to the window mist limit, a compressor is actuated, the air is blown out from a DEF blowout port into a cabin, or an air volume in a blower is increased to prevent the mist on the windshield and delay switching to the outside air lead-in mode as much as possible. Consequently, air conditioning operation in the inside air circulating mode is performed while the mist on the windshield is suppressed to prevent deterioration in the inside air quality.

  • Patent number: 8899311
    Abstract: When there is no occupant in seats other than a driver seat during a foot mode, an air-conditioning controller executes a single seat concentration mode to prevent blowing of warm air to a passenger seat and a backseat by closing foot outlets on a passenger seat side and a backseat side. In this case, in order to maintain an air volume blown from the foot outlet on a driver seat side when the controller changes the mode from the normal foot mode to the single seat concentration mode, the controller sets a blower level to be lower than in the case of the normal foot mode with respect to the same target blown air temperature.

  • Publication number: 20140349560
    Abstract: A vent assembly is disposed within an interior space of a vehicle for opening and closing fluid communication between the interior space and an exterior of the vehicle. The vent assembly includes a housing defining a plurality of openings and a plurality of vanes disposed in the openings. An actuator mechanism moves the vanes between an open position and a closed position, and includes a shaped memory alloy (SMA) member for actuating the vanes between the open and closed positions. The SMA member is activated when a hatch of the vehicle is opened to move the vanes into the open position and thereby open fluid communication between the interior space and the exterior to alleviate excessive air pressure buildup during closure of the hatch.

  • Publication number: 20140295746
    Abstract: A ventilation system for a passenger transit vehicle that comprises a passenger compartment. The ventilation system comprises a variable speed fan for providing outside air to the passenger compartment, wherein within a given ambient temperature range, the speed of the variable speed fan is controlled such that the air speed produced by the variable speed fan increases with increasing ambient temperature. The ventilation system further comprises a duct system fluidly connecting the variable speed fan to an air diffuser that directs the air from the variable speed fan towards the passengers within the passenger compartment. The cross sectional area of the duct system decreases along its length for providing substantially constant air pressure along its length. The ventilation system is able to provide outside air into the passenger compartment at an air flow speed of greater than 0.15 m/s.

  • Publication number: 20140273785
    Abstract: An HVAC control system for directing the flow of air in a work vehicle's HVAC system responds to the orientation of a rotating seat within the work vehicle's cabin. The seat may rotate between at least two operational positions, such that the operator of the work vehicle may control a forward or a rearward implement. The HVAC control system includes one or more detectors for detecting the position of the seat. A control module receives output from the detectors and allows or prevents the flow of air through particular ducts in the HVAC system based on the seat's position. The control module may actuate one or more doors to open and close ducts as needed. The control module may operate a first door to open or close forward ducts and a second door to open or close rearward ducts depending on whether the seat is facing forward or rearward.
