  • Patent number: 9709298
    Abstract: An indoor air-conditioner unit comprises an air duct, an air outlet connected with the air duct, and an air deflector guiding directions of air flow from the air-conditioner. A volute tongue is provided in the air duct and near an outer end of the air outlet. Wherein, the indoor air-conditioner unit further comprises a central support mechanism, which is elastically arranged between the central part of the back of the air deflector and the volute tongue, thus a complete seal of the air outlet can be achieved when the air deflector is closed, i.e., there are no gaps in the air outlet.

  • Publication number: 20100304659
    Abstract: The disclosure is a calibrated airflow measurement system for measuring air flow through a ceiling vent having a moveable vane. The airflow flows through the ceiling vent in laminar flow into a ceiling. This allows the moveable vane of the ceiling vent to be reversibly responsive to airflow through the room and allows for the vent to be calibrated to disperse a predetermined amount of air into the room.

  • Patent number: 6929542
    Abstract: Air deflector for deflecting an air flow from an air register including a pair of mounting members adapted to be mounted on opposite sides of a venting member of the air register device and a laterally expandable guide member arranged between the mounting members. The guide member is expandable to different lengths to thereby enable the length between the mounting members to vary and allow the air deflector to be used for different sized air registers. The guide member is pivotally connected to the mounting members and pivotable into different angular positions relative to the mounting members to thereby enable the air flow to be deflected into different directions depending on the angular position of the guide member.

  • Patent number: 6290597
    Abstract: A slot diffuser includes a pair of elongate and parallel side walls spaced by pairs of bridges. The bridges include feet that slide along receivers in the side walls such that the bridges can be positioned at any location therealong and provide support to the bridges and stability to the diffuser. The bridges include slots that extend between the side rails and that receive ends of air flow control blades. The air flow control blades include an elongate planar portion supported by rods extending outwardly on either side of the planar portions to support the blades in the slots. At a lower end of each planar portion opposite the rods is a foot that extends perpendicularly outward therefrom. Each side rail includes an inwardly projecting flange that is sized and positioned to slidably receive the foot of an associated blade such that the blade may be manually moved both within the slot and along the flange to properly position the blade during the installation or subsequent modification.

  • Patent number: 5924922
    Abstract: A ceiling ventilation inlet includes a housing having an air inlet aperture, an air outlet aperture, and a baffle supported for linear movement adjacent the air outlet aperture. A spring is positioned such that the baffle moves dependant upon air pressure difference between the confinement space and the external environment. Air entering the housing opens the baffle and enters the livestock confinement building in a 360 degree dispersion pattern. The spring causes the baffle to direct the flow of air into the confinement space at a near constant rate so as to optimize ventilation. The greater the air pressure difference between the confinement space and the external environment the greater the air outlet area becomes. Since the inlet is responsive to the pressure difference and the air outlet area increases or decreases in size, the airflow velocity entering the confinement space may be optimized at a near constant rate.

  • Patent number: 5261857
    Abstract: A ceiling vent diffuses air from a heating or cooling system in a laminar flow into a room for optimum dispersion in the room. Inlet air strikes a hinged vane within the vent. The vane deflects the air in a narrowing air way along a continuous concave curvature and extending all the way to the outlet opening of the vent. The vane responds to the force of air flow to narrow or enlarge the air way and, thus, regulate the velocity of air exiting the vent. A curved air catch associated with the vane directs the outflow of air and also laterally disperses air within the vent. The vent maintains a relatively constant velocity and diffusion of air into a room despite variable flow rates from the source of air.

  • Patent number: 5088388
    Abstract: An all season, adjustable fresh air intake for agricultural buildings is claimed which is adapted to adjust the volume, velocity and direction of fresh air drawn from the outside, through the intake and into the building suitably by exhaust fans. The intake is firstly comprised of a hollow building body. The body extends from outside the building, through a ceiling or wall of the building with an opening extending into the building for bringing fresh air into the building from the outside. An air intake housing with at least one opening is attachable to the building body on the inside of the building at the body opening through which fresh air from outside may flow. A pair of independently adjustable deflectors are pivotally mounted onto the housing adjacent the opening in opposing relationship to each other to manually open and close the opening as well as direct the fresh air from ceiling to floor as the fresh air is drawn into the building through the fresh air intake.
