Abstract: A prefabricated wall with a ventilation mechanism is provided in the present invention. Generally, it includes a ventilation mechanism that lets air exchange in a room from the wall. People can adjust the inlet airflow with a controller. The ventilation mechanism has several holes on the outer surface which face to outside. The outdoor air can pass through the holes and filter into the inner room, consequently fulfilling the function of the ventilation duct. The room equipped such a prefabricated wall does not rely on an HVAC system to have fresh air exchange.

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: A unidirectional valve for venting moisture from a window having at least two panes or lights, the panes or lights defining an air space therebetween, is provided. The valve includes: an elongated body having an interior passage formed lengthwise therein, wherein at least a portion of the elongated body is adapted to be inserted directly through a window pane and into the air space formed between the panes; at least one resilient plate pivotally connected to the elongated body; wherein the resilient plate moves in response to changes in fluid pressure within the air space formed between the panes of the window, and wherein the movement of the plate opens the interior passage for allowing moisture-laden air to pass therethrough and out of the air space or closes the interior passage for preventing air from flowing back into the air space between the panes.

Abstract: A window element has a cover pane which is substantially flush with an outer skin of an aircraft or other transport, achieving a fluid-dynamically favorable, substantially unbulged exterior surface. As a result of the presence of an additional back-ventilated cover pane arranged in front of the actual outer pane of the window element, a fluid-dynamically favorable integration of the window element into the outer skin of an aircraft fuselage airframe is achieved. Any deformation, such as any buckling or bulging of the outer pane of the window element, as a result of a difference in pressure between the interior of the aircraft fuselage airframe and the exterior space at cruising altitudes, has no fluid-dynamically disadvantageous effect. The outer pane is covered by the cover pane which remains substantially undeformed with respect to the outer skin of the aircraft fuselage airframe, for example. Any deformation of the cover pane is largely eliminated by back-ventilation.

Abstract: An airflow management device is described that assists air cooling, exchange, and circulation of interior spaces by creating inward and outward airflow through a window opening. The device measures temperatures outside and inside a room, and determines when to exhaust warmer ceiling air and to draw cooler outside air. The exhaust component of the device captures warmer air at a higher level of the room and exhausts it through a window opening at a lower level. The intake component of the device draws cooler outside air through the window opening and discharges it into the room at a lower level than exhaust inflow. By expelling air from a high level and drawing it at a lower level, the room vertical temperature gradient is maintained thus optimizing cooling effectiveness. By microcontroller regulation of inflow and outflow, air pressure equilibrium between outside and inside is maintained thus maximizing airflow efficiency.

A first of the glazing layers is adjacent a first of the airflow cavities, a second of the glazing layers is adjacent a second of the airflow cavities, and a center glazing layer is between the first and second glazing layers and separates the first and second airflow cavities. Airflow cavity openings are located adjacent the uppermost and lowermost extents of each airflow cavity, and airflow is enabled through the first airflow cavity between the openings thereof and enabled through the second airflow cavity between the openings thereof. The window system operates as a crossflow heat exchanger capable of supplying fresh outdoor air to an enclosed indoor space, while thermally tempering the incoming fresh air with outgoing indoor air.

Abstract: A window unit is provided for reducing heat loss through the window while at the same time providing a desirable inflow of prewarmed ventilation air to maintain interior air quality and thermal comfort. The window unit comprises an outer window frame and a sash frame designed to support an inner dual pane sealed window unit together with a separate outer single pane thus providing a triple pane action. The sash frame is also modified to provide a slot at the lower edge for entry of exterior air into a channel defined between the outer pane and the outer surface of the sealed window unit. The building is maintained at reduced pressure to cause air to flow in a laminar action along the channel toward a slot above the top of the sealed window unit so that heat escaping from the outer pane of the sealed window unit is carried by the laminar air flow back through the upper slot and into the interior of the building.
