Abstract: A system and method for controlling air flow through a passenger cabin and battery pack of a vehicle having a battery module is disclosed. A HVAC controller communicates with a battery pack controller to assure that air flow from the passenger cabin through the battery pack, and either out to atmosphere or returned to the passenger cabin, is coordinated to obtain desirable passenger cabin heating/cooling and battery cooling.

Abstract: An air curtain doorway for preventing cross-filtration of air at a doorway between a relatively warm area and a relatively cool area has duct work and an air mover. The duct work includes a supply air duct and a return air duct at opposite sides of the doorway joined by an intermediate air duct at the top of the doorway. The intermediate air duct houses the air mover, which creates an air stream circulated through the duct work that blows an air curtain from the supply air duct to the return air duct. The return air duct has an enlarged collector chamber upstream of an adjustable return air inlet aperture into which the downstream end of the air curtain is drawn. The supply air outlet aperture is at the base of a nozzle that has an upper portion that directs the air curtain toward the warm side and a lower portion that directs the air curtain toward the cold side of the doorway.

Abstract: A valve including a film having edges and a plurality of openings disposed between the edges is supported by the housing of an automotive a heating, ventilation and air conditioning system to control the flow of air blown into the passenger compartment. The film has recesses along both edges. The film is reciprocated along the curved path by a first pair of sprockets supported on a shaft and presenting first axial teeth engaging the recesses along the edges of the film (FIGS. 3-5), or a second pair of sprockets having first radial teeth engaging the recesses in the edges of the film and driven from the shaft by bevel gears (FIGS. 5-8), or third pair of sprockets having second radial teeth engaging the recesses in the edges of the film and driven by a spur (FIG. 9), or by the spur directly engaging the recesses in the edges of the film (FIG. 10).

Abstract: A louver apparatus includes a case member, a connecting member, and a louver pivotally secured to the case member, including a shaft portion including a shaft body being in the form of a substantially cylindrical shape, and a head portion being in the form of a substantially regular polygon, and being located at a tip end portion of the shaft body. At least a part of the head portion protruding radially from the shaft body. The connecting member includes an axial hole being in the form of a substantially regular polygon. The head portion is arranged to pass through the axial hole only at predetermined positions, and to be held not to pass through the axial hole at positions other than the predetermined positions.

Abstract: A louver type roof structure includes a plurality of elongated parallel slats mounted on slat hinges pivotally supported on carrier beams transverse to the slats. The slats are pivotable between a closed position in which their longitudinal adjacent edges overlap each other, and an open position in which the slats are spaced apart. The slat hinges are mounted to the slats at their lower surface and allow pivoting of the slats between the closed position and an extreme open position by an angle of at least 90°, preferably 110°. The pivoting axis of the slat hinge is disposed substantially under the longitudinal edge of the slat which is overlapped by the adjacent slat. The roof structure may comprise a border slat adapted to be displaced when urged by an adjacent slat when the latter pivots towards its extreme open position.

Abstract: A motor vehicle air-conditioning system (1), including a plurality of air ducts (7?, 7?) having a flap for controlling the air flow therein. A single flap (6) is provided for controlling at least two air ducts (7?, 7?) which serve for the temperature stratification of the air streams.

Abstract: Ventilating system including a total heat exchanger at a region where an air supply duct, a passage for supplying outdoor air to a room, and an air discharge duct, a passage for discharging room air to an outside of the room, cross for making room air and outdoor air to heat exchange, an air supply fan connected to the air supply duct for drawing the outdoor air and discharging the outdoor air to the room, an air discharge fan connected to the air discharge duct for drawing the room air and discharging the room air to an outside of the room, and a flow guide between the air supply/discharge fans and the total heat exchanger for guiding flow directions of the room air and the outdoor air, thereby reducing a flow resistance and making the heat exchange efficient.

Abstract: An exhaust device is used to exhaust air from inside of an apparatus to outside. The exhaust device includes a louver with blades arrayed in a lattice, the louver being detachably engaged with a trough hole in a cover of the apparatus such that the louver can rotate freely in a clockwise and a counterclockwise direction. A fan unit provided separately from the louver is positioned upstream in an airflow direction than the louver, so as not to rotate when the louver is rotated. The blades form an angle between 0° and 90° with a plane perpendicular to a central axis of the louver.

Abstract: An improved air diffuser is provided, including a housing having a bottom and an upwardly extending side wall with air slots to receive air. The housing supports a grille, and a flow regulator fits within the housing. The diffuser is configured to be secured to a floor by a mounting assembly, including a trim ring and a plurality of retaining mechanisms. The trim ring defines a flange and brackets for receiving the retaining mechanisms. Each retaining mechanism defines an L-shaped mount having horizontal and vertical legs. A cantilevered latch extends from a back of the vertical leg so that, when the vertical leg is inserted into one of the brackets, the latch secures the retaining mechanism to the bracket. The horizontal leg and the flange of the trim ring define a space therebetween for engaging a floor and thereby securing the housing to the floor.

Abstract: The present invention is a fume hood capable of exhausting contaminant, having an air pipe in a sash and a suction slot corresponding to the air pipe deposed at the front rim of the bottom surface to obtain an air curtain, where contaminant is efficiently prevented from leakage and energy is saved.

Abstract: An air duct outlet housing has spaced-apart top and bottom walls, and spaced-apart first and second side walls that define an air passageway with an inlet and outlet. First and second air deflection members include elongated first and second panels with respective proximal and distal end portions. A flange extends from each distal end portion of the respective first and second panels. The first and second panel proximal ends are pivotally secured to the housing and are movable between first and second positions. The first and second panels are in face-to-face relationship with the respective first and second side walls when in respective first positions. The first and second panels extend in respective directions that are transverse to the respective first and second side walls when in respective second positions.
