Abstract: An inflatable barrier allows separating air in a first space from air in a second space to provide containment. The inflatable barrier may include an inflatable bag with edge seals in the form of parallel tubes. The bag receives air from an air mover through a first opening. It has a carrier for a vent that releases air while the bag stays inflated. A tension rod prevents the bag from bulging out of shape. The bag may be hung from an expandable rod. An internal channel may route air through the whole bag. The inflatable barrier may comprise an outer sleeve and two or more inflatable inner chambers. The circumference of a main sleeve matches the circumference of a combination of the inner chambers. The inner chambers include an air inlet/outlet. The outer sleeve may have connector halves to couple the barrier with another barrier, or to couple the main sleeve with a top, a bottom, or an extension.

Abstract: An offset window mount fan includes two or more independently controlled fans controllable to move air in the same direction or in opposite directions. A housing substantially offsets the fans from a direct passage of air into the room. In one embodiment, the fans are mounted in a housing perpendicular to the window, air traveling through the fans turning 90 degrees to pass through the plane of the window and 90 degrees down into the room. Each fan includes a temperature sensor to measure temperature of air moving through each fan. The fans are energized periodically for a short time period to make accurate temperature measurements. When the combined temperature measurements indicate an advantage from fan operation, the fans are activated.

Abstract: Various embodiments of air conditioner units are detailed.

Abstract: Disclosed is a heat exchange conduit formed between pre-fabricated building panels and a daylighting section integral within pre-fabricated, structural panels. The daylighting section has the capability to take ceiling air (or air below free-standing arrays) and either return it to the building during heating months, reject the heat, or shunt it for other uses after being warmed through a dual pane glazing assembly with infrared rejection. During summer days, this allows for dramatic reduction in building cooling demand. Heat exchange surfaces within the conduit are thermally tied to the exterior components of the panels to allow heating by solar insolation or cooling to night sky or air. An advanced insulation system adds to thermal performance and sealed insulation cavities prevent moisture degradation of R-Values. Passage through the heat exchange conduit allows for active whole roof solar collection in spring/fall and night cooling capability during summer night operation.

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: This invention relates to two devices that are used to let fresh air in or through a window or opening but at the same time keep rain or any other kind of precipitation out. This is a device that will enable people to keep a window or an opening open even in inclement weather or when precipitation of any kind threatens to enter the opening or window. This is a device that will also save energy as it will significantly decrease the use of air conditioning in homes and offices.

Abstract: A heat transfer inhibitor system to minimize the heat transfer through the structural opening closures with an interior and an exterior panel such as windows, doors and skylights that are the weak links in interior insulation. By moving a stream of constant temperature air through a space between the external panel and the interior panel, the temperature differential between the exterior surface of the internal panel and the interior is minimized thus reducing the load and maintenance costs on heater/AC systems. It also reduces the required size and costs of installations.

Abstract: A self-contained air conditioner unit incorporates an energy recovery ventilator portion that brings about several changes of room air per hour with outdoor fresh air. There is an outdoor air intake plenum which furnishes the fresh air and the condenser air for the condenser coil, and a return air plenum. Air from the room return air plenum is HEPA filtered and conducted to the evaporator coil and evaporator fan, and is supplied back into the conditioned space. The energy recovery ventilator has a counterflow heat exchanger core situated between the return air plenum and the fresh air intake plenum, as well as two ventilation fans, one (or both) of which may be of variable or multiple speed. By controlling the fan speeds, it is possible to produce a neutral pressure, a positive or overpressure, or a negative or underpressure in the conditioned space. The unit can be wheeled into place and installed easily by personnel without special training.

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: A system and method are provided which capitalize on heating and air conditioning ductwork to draw fresh air through a house and cool the attic. Outside air enters through open windows and is drawn into return air vents. A blower fan, which is housed within the duct assembly or an air handling unit, draws air through the return duct work and exhausts into an exhaust duct. A damper in the exhaust duct has an exhaust position and a return position. In the exhaust position, air exhausts through a vent in an attic space, where the attic space is vented to the outside. In the return position air continues to the heating and air conditioning unit. The present invention provides a means to direct the fresh air flow through a house using return vents while cooling the attic space without the use of an attic fan.
