Abstract: The application provides a fresh air purification window for preventing haze. A ventilation device is provided with an upper layer and a lower layer and partitioned by a transverse middle-layer partition plate, an exhaust fan is mounted in the upper layer, an air feeder is mounted in the lower layer, an air inlet grille is formed on the upper layer through front-layer glass, and a half-closed space with an air cavity unidirectionally provided with an exhaust opening is formed by the upper layer, upper-layer glass, a middle-layer separation partition plate and air cavity one-sided glass. The fresh air purification window has the effects of lowering the shielding light ray of the current purification window and enabling the current purification window to be compact in structure.

Abstract: A window air handler mounted to a window admits a supply of air from inside the building at the top of the window and blows that air downwardly and onto the inner surface of the window. A leg depends downwardly from an air inlet, to air outlets which express the air across the width of the window. The air can be ambient, or heated. The so-expressed air warms the glass enough to avoid condensation on the glass, or to remove and absorb condensation which has already formed on the glass. The air handler can comprise a single leg extending down along one side of the window or two legs extending down along opposing sides of the window. Air inlets are proximate the tops of the legs, and air outlets are below the inlets.

Abstract: The present invention relates to a method of treating a glazing panel from an inside location. Moreover, the present invention relates to a method of treating glazing panels used in windows and patio doors. Initially, a hole is formed on both inside and outside panes on windows and on the side and outside frames of patio doors. Next, a filter is attached to the outside pane to cover the hole whereby the filter membrane is designed to allow the passage of air and inhibit the ingress of moisture. Finally, a seal is used to cover the hole on the inside pane or to ensure that the building air does not enter the interior of the glazing panel. Where the panes are tempered glass, the hole(s) may be drilled through the frame. If necessary, one or more tubes may be inserted through the hole. Various kinds of filters are disclosed.

Abstract: An air handler draws air from inside a building, optionally from a building space heating system, and expresses that air such that the air travels along the inside surface of a window glazing unit which is susceptible to condensation. The air can be expressed at ambient temperature or with a modest amount of supplemental heat. As the air is expressed onto the window, a convection curtain of relatively warmer air passes adjacent the inside surface of the glass, warming the glass enough that condensation does not form on the glass. The system can be controlled using a sensor, optionally controlled by a computer or other controller, which controls the air flow according to needs sensed at the window. Such computer can be used to provide individualized control of condensation on each of multiple windows. A blower may be used to achieve increased control of rate and persistence of air flow.

Abstract: The present invention provides an apparatus for venting an airspace formed between an ornamental window and a protective panel. The venting means includes at least one pair of vent openings, one for air to enter the airspace and one for air to exit. These vent openings include a path through the frame holding the protective panel to an interior opening which is to the airspace. The vent openings, the paths and the interior openings must be of adequate size to minimize the range of temperature and moisture within the airspace. It is recommended that effective vent openings are at least one square inch for every 2000-2500 square inches of ornamental window.

Abstract: The present invention relates to a window having ventilation equipment.

Abstract: A dewpoint cooler comprises: a first air circuit and a second air circuit coupled thereto via a heat-conducting wall, through which two circuits can flow two media, wherein the second medium contains a gas, heat-conducting wall break-up means for breaking up at least the thermal boundary layer (50), the laminar boundary layer and the relative humidity boundary layer in both media, which break-up means comprise heat-conducting protrusions; wherein the surfaces of said wall and the break-up means are covered with a hydrophilic coating, which can absorb an evaporable liquid, retain it and relinquish it again (100), such that the wetted coating, the heat-conducting surfaces and the break-up means are cooled. A wetting (150) unit for subjecting the secondary medium to wetting by the evaporable liquid such that evaporated liquid entrained by the secondary medium extracts heat from the primary medium via the wall.

Abstract: An air jet system is provided that includes a refrigerated display case. The novel apparatus includes a glass display window, which is transparent and has an outer surface for viewing the contents of the display case. The unit also has a front bar that defines an air passage therein when connected to a bracket and also defines a channel at one of its ends which has at least one opening. The bracket connects and supports the display window and the front bar on the display case. A nozzle is positioned in the channel and has holes therein for air passage and is positioned to direct air through the opening in the end of the front bar and onto the outer surface of the display window. A centrifugal blower is connected to the bracket and is adapted to blow air through the air passage and through the holes in the nozzle so that air is guided over the outer surface of the glass display window to eliminate moisture condensation.

Abstract: A double-pane aircraft cabin window arrangement avoids fogging, frosting, or icing of the window without using any active pressure regulating system or other active components. An inner pane and an outer pane are held in a window seal that is mounted in a frame connected to the aircraft fuselage. An interspace is formed between the two panes and sealed by the window seal. A condensation inducing tube is connected by a hose to an adapter tube, which passes through the window seal into the window interspace. The condensation inducing tube is connected in a direct thermally conducting manner to the outer fuselage skin of the aircraft. An open end of the condensation inducing tube is arranged to receive pressurized air from the aircraft cabin interior. As the air flows through the condensation inducing tube, any condensable moisture in the air condenses out on the interior walls of the tube, so that only dry air flows into the window interspace.

Abstract: An air distribution system for directing air over an inner surface of a window includes an air distribution outlet including an elongate air duct and a distribution divider for dividing the duct longitudinally to define inlet and outlet portions. The inlet portion has an inlet port at one end of the duct for communication with an air supply source. The divider defines a longitudinal communicating passage for air communication between the inlet and outlet portions, the passage increasing in cross-section with increasing distance from the one end of the duct and the inlet port. The outlet portion has an outlet port extending longitudinally along one side of the duct. The duct is located in the sill of a window such that air may be directed for an air supply source to the inlet port, through the duct, and over the surface of the window.

Abstract: A dual glazing window having a removable glazing panel is provided with a breather system connecting the air chamber between the glazing panels with the outside ambient air by routing an outwardly facing channel into the window rail or stile member either on its end edge or side face. The abutting rail or stile member will close the open side of the channel in the end edge while the adjacent glazing panel closes the channel in the side face. A breather sleeve is press fitted into the channel to protect the wood from absorbing moisture.
