Abstract: An assembly for covering a grill of an air conditioning unit that fits through a wall comprises a rigid or semi-rigid cover having a top, a perimeter flange to which a flexible sealing material is affixed, and having sides, the top having four corner apertures for insertion of the cords. Four elastic cords have a hook at one end and having a barrel lock slideably engaged to a second end. The barrel locks of the elastic cords collectively urge the cover against the wall so as to create an air-tight seal between the cover and the wall. The cover is urged against the wall and prevents unwanted upward hot air flow and downward cold air flow in the winter when the air conditioning system is not in use.

Abstract: An assembly for covering a grill of an air conditioning vent in the winter comprises a cover having a frame that may have a hole on a top surface and sides including a compressible material along its perimeter for sealing a vent area. In one preferred embodiment, the assembly includes an elastic cord having a looped end and a free end, the looped end being of adjustable size and having two hooks slidably connected to the cord. The hooks are configured to attach to the grill and pulling the free end of the cord tightens the looped end and the hooks. The free end may be attached to the cover so that sliding a barrel lock up the cord urges the cover against the vent area and prevents unwanted upward hot air flow and downward cold air flow in the winter when the air conditioning system is not in use.

Abstract: An air register for covering an air duct opening in a space ventilated by a forced central air system.

Abstract: An air register cover assembly (1) comprising a front panel (2) having a face and rear portion (18) and (19), at least one spacer (4) located on the rear portion (19) and a means for hanging the front panel (2) in front of an air duct (21). An alternate embodiment may include an air register housing (5) which is fitted within an air duct. The housing (5) includes housing openings (7) to permit air from an air duct (21) to be expelled. The front panel (2) may include an insulated backing (8) having spacers (4) attached thereto. When in use, the air register cover assembly (1) re-directs the air flow so as to be expelled around the front panel (2), rather than directly into a room. The use of the present invention not only circulates air within a room, but it also makes air registers more attractive.

A method for controlling air circulation within a room having an aisle between racks with computer systems mounted thereon comprises supplying cooling air to computer systems in the racks via holes in a floor of the room and using a deflector to reduce flow of cooling air along the aisle toward an air intake of a cooling unit without passing the computer systems.

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.

Abstract: A filtering system which is secured to a traditional air register. The filter uses a flange adapted to encircle the outlet of the traditional air register. Connected to the flange is an air filtering material which collects the dust and pollen at the air register, before the air enters the room. In one embodiment of the invention, an electro-static charge is used by the filtering material to assist in the collection of the dust and pollen. To assist the user in determining when the filter system should be replaced, the air flow pushes a flag; hence as the air flow decreases as the filter becomes clogged, the location of the flag notifies the user that the air filter system should be replaced. While a hook-and-loop fastener is sometimes used to secure the filter to the air register, the preferred embodiment uses a releasable adhesive.

Abstract: A cover for use with an air register. The cover includes a base part which extends about the opening through the register and is positioned between the register and the floor. Hinged to the cover base part is a deflector part which extends upwardly over the top of the register so as to cover the register opening when there is no air flow through the register. Upon air flow through the register, deflector part is blown outwardly relative to the register so as to expose the opening in the register.

Abstract: A device for diverting air flow upward from an air outlet of an air conditioning system to prevent impingement of cold air on vehicle occupants contains an air foil that changes the direction of air exiting the air outlet from horizontal to vertical.
