20120067559 | SYSTEM AND METHOD FOR ENVIRONMENTAL MANAGEMENT OF A VEHICLE - A system and method for environmental management of a vehicle automatically operates a vehicle climate control system to quickly and efficiently defog a vehicle windshield, while still operating at or near environmental comfort guidelines determined by a vehicle occupant. The method may be executed by an HVAC control system that is configured with a preprogrammed algorithm to operate an HVAC to achieve the desired results. A number of sensors can provide inputs to the control system, which can also receive inputs from a number of manual overrides operable by an occupant of the vehicle. The preprogrammed algorithm is configured to act on the various inputs to operate the HVAC to strike an appropriate balance between occupant comfort and windshield defogging. | 03-22-2012 |
20120247747 | AIR CONDITIONING APPARATUS - A vehicle cabin air conditioning apparatus including an airflow selecting mechanism movable between a first position to provide a first airflow mode and a second position to provide a second airflow mode. The airflow selecting mechanism restricts first airflow from flowing from a first airflow conduit to a second airflow conduit when in the first position, and permits the first airflow from flowing from the first airflow conduit to the second airflow conduit when in the second position. An electronic control unit is configured to control a first blower based on a user set front cabin airflow level and a second blower based on a user set rear cabin airflow level when in the first airflow mode. The electronic control unit controls the first blower based on the user set front cabin airflow level and the user set rear cabin airflow level when in the second airflow mode. | 10-04-2012 |
20130020064 | Heating, Ventilation And/Or Air Conditioning System, In Particular For An Electric Automobile Vehicle - The aim of the present invention to provide a heating, ventilation and/or air conditioning system ( | 01-24-2013 |
20130306298 | HVAC TEMPERATURE STRATIFICATION IMPROVEMENT TECHNIQUE - An air distribution door for use in a ventilation system with anti-stratification feature is provided. The door includes a tab extending from the main body of the door. The tab partially disrupts air flow going into the heat exchanger. This disruption slows high velocity airflow going across the heat exchanger and causes a more uniform thermal transfer distribution to the air from the heat exchanger, which provides preferred comfort by the user. | 11-21-2013 |
20140060796 | AIR CONDITIONER FOR VEHICLE - An air conditioner for a vehicle includes a blower; a heat exchanger that heats the blown air by heat exchanger between blown air and a heat medium, a control device, and an air outlet mode switching device that switches between air outlet modes by switching proportions of air flow blown out from outlets which includes a face air outlet and a foot air outlet, wherein the control device limits the availability factor of the blower based on a temperature of the heat medium; and relaxes limitation on the availability factor of the blower when the air outlet mode is a bi-level mode in which the blown air is blown out from both of the face air outlet and the foot air outlet. | 03-06-2014 |
20140096945 | HEATING AND COOLING SYSTEM FOR OCCUPANTS OF THE REAR PORTION OF A VEHICLE - A heating, ventilation, and air conditioning (HVAC) system configured for use in a vehicle to provide a perceived comfortable thermal environment to an occupant seated in a rear portion of a vehicle cabin. A heat exchanger provides a first airstream characterized as having a first temperature to an air moving device configured to generate a second airstream characterized as having a second temperature. The second airstream comprises a mixture of the first airstream and cabin air drawn from the rear portion of the vehicle cabin. The air moving device may be disposed in the rear portion of the vehicle. The HVAC system further includes a nozzle that may be configured to direct the second airstream toward an occupant in the rear portion of the vehicle cabin to provide spot conditioning. | 04-10-2014 |
20140131026 | MULTI-FUNCTION HVAC AIR SYSTEM FOR VEHICLE - A vehicle air circulating system comprises a controller, an interior condition sensor attached to the controller, an instrument panel, and a deployable register assembly attached to the controller and pivotably attached to the instrument panel. The register assembly includes a first register and a second register and is movable between a closed position in which the first register is recessed within the instrument panel and is thus obstructed and an open position in which the first register is deployed. The second register remains unobstructed whether the register assembly is in its closed or open position. The deployable registers provide directional control for pull down conditions. Once the desired conditions are achieved, the deployable registers lower into the instrument panel and the other registers provide a larger opening to direct the air overhead at lower velocities keeping the vehicle cabin cool while not blowing in the direction of the occupants. | 05-15-2014 |
20140305626 | CALCULATION OF FLOW IN AN AIR SYSTEM - A method is provided for determining an air flow in a vehicle air conditioning system that comprises an inlet; a plurality of outlets; at least one air duct for guiding air from the inlet to the outlets, each air duct being characterized by a predetermined flow resistance coefficient; at least one flap characterized by a flow resistance based on a degree of opening of the flap; and a fan for creating an air flow from the inlet to an outlet. The method comprises determining a total equivalent flow resistance between a predetermined location in the system and an interior of the vehicle, wherein flow resistances are treated as resistances in an electric circuit, and a total equivalent flow resistance is determined. Treating a pressure drop as equivalent with a voltage drop, the air flow can be determined, as the pressure is equal to the resistance times the flow squared. | 10-16-2014 |
20160144685 | AIR CONDITIONER FOR VEHICLE - An air conditioner for a vehicle includes: a casing; an air blower; and a mode switching portion switching an inlet mode to draw air into the casing and an outlet mode to blow out air to the vehicle interior. The casing has a driver seat inlet port from which air in a space adjacent to a driver seat is drawn in. The mode switching portion is configured to be switchable between a normal mode during which air drawn in from at least one of air inlets is blown out from both of a driver seat outlet and a passenger seat outlet and a driver seat mode during which air drawn in from the driver seat inlet port is blown out from the driver seat outlet. The driver seat inlet port is located in a region exposed to the space adjacent to the driver seat. | 05-26-2016 |
