  • Patent number: 7198567
    Abstract: A desktop-type ventilation system generally includes a ventilation hub having at least one vent and at least one fume hood connected thereto. The fume hood(s) generally include a pair of side walls, wherein each is disposed at an angle for directing and causing air to be funneled toward the vent. The fume hood(s) include a front wall defining an inlet orifice, a rear wall having an outlet orifice for connection to the vent, and a top wall disposed at an angle of elevation from the rear wall to the front wall. The front wall is detachably securable to the side walls and the top wall such that the fume hood(s) may be broken down after use and nested for storage. The ventilation hub may detachably secure to a work surface such that it may be removed therefrom and conveniently stored when not in use.

  • Patent number: 7195555
    Abstract: An air duct outlet includes a housing having spaced-apart top and bottom walls, and spaced-apart first and second side walls extending between the top and bottom walls to define an air passageway having an inlet and outlet. A first air return passageway is located adjacent to the first side wall, and diverts a portion of an air stream flowing through the air passageway as the air stream adheres to the first side wall. A second air return passageway is located adjacent to the second side wall, and diverts a portion of an air stream flowing through the air passageway as the air stream adheres to the second side wall. The continuous diversion of portions of an air stream flowing through the air passageway by the first and second air return passageways causes an oscillating, sweeping motion of the air stream as it exits from the air passageway outlet.

  • Patent number: 7163456
    Abstract: Engine cooling water is charged to a flexible diaphragm member (3d) to expand the flexible diaphragm member (3d) so that the substantial sectional area of an air passage (3b) is decreased when a ventilation resistance, in an air conditioning casing (2) in a maximum heating or a foot mode, is increased. On the other hand, the engine cooling water is discharged from the flexible diaphragm member (3d) to deflate the flexible diaphragm member (3d) so that the substantial sectional area of the air passage (3b) is increased when a ventilation resistance, in the air conditioning casing (2) in maximum cooling or face mode, is decreased. Thus, the property of a fan (3) can be changed into a property suitable for foot mode having a large ventilation resistance, while heating air is being supplied.

  • Patent number: 7144320
    Abstract: An air distribution arrangement is adapted to be arranged in a cabinet for housing rack-mounted equipment that generates heat in use. The arrangement can be part of the cabinet when constructed or it can be an add-on feature. The arrangement includes plenum structure comprising side walls and a top wall that cooperates with the front door of the cabinet and the faces of the rack-mounted equipment to define a plenum. An air box in the cabinet draws ambient air from adjacent the floor into the plenum at a rate of at least 850 cfm. The ambient air is cooler than the air in the cabinet. The faces of the rack-mounted equipment have openings for receiving the ambient air to cool the interiors thereof. After cooling the rack-mounted equipment the air can be exhausted back to the ambient. The side walls and the top wall of the arrangement are adjustable to permit adjustment of the depth of the plenum. Pressure in the plenum can be relieved by slots in the plenum structure.

  • Patent number: 7101279
    Abstract: The present invention provides a solar-powered ventilation system for an attic or rafter space that mimics the appearance of the roofing material and thus has little effect on the appearance of the building. The vent has two pieces, a primary vent and a secondary vent. The primary vent is installed on a roof deck over a ventilation opening cut through the deck. The secondary vent is constructed to look like the surrounding field tiles and is installed over the primary vent. The secondary vent includes a solar panel preferably attached to the top surface of the secondary vent. One or more vent openings in the secondary vent and an opening in the primary vent conduct air between the attic or rafter space and the outside. In certain preferred embodiments, a solar-powered fan is also preferably located underneath the secondary vent.

  • Patent number: 7094142
    Abstract: A portable device that is placed between the ambient air outside an existing enclosed space and the existing enclosed space that pulls the ambient air through an interchangeable array of air cleaning modules and delivers the cleaned air from the air cleaning modules into the existing enclosed space. The air cleaning modules are disposed outside the existing enclosed space so that only cleaned air is drawn into the existing enclosed space. The air cleaning modules can also be capped for easy and safe disposal after use. The air cleaning modules are in fluid communication with an electric fan that is disposed inside the existing enclosed space through an air flow inlet that is part of an expandable window insert. Accordingly, the cleaned air delivered to the existing enclosed space provides its inhabitants with clean breathable air and increases the air pressure in the existing enclosed space which prevents contaminated air from the external environment from entering the existing enclose space.

  • Patent number: 7094143
    Abstract: A security housing contains a housing body having ventilation openings for supplying air to a heat source, in which air convection takes place for dissipating heat. First air guide elements are disposed in the housing body on a first side of each of the ventilation openings and are shaped for partly covering the ventilation openings. The first air guide elements each have a base integrally molded on the housing body, the bases are spaced apart from each other such that, in each case one of the ventilation openings is further defined. A removable security housing part is disposed inside the housing body and forms an air guide duct. Second air guide elements are disposed in the air guide duct and are shaped such that they cover the ventilation openings and the first guide elements such that, non-rectilinear air guidance is ensured.
