The filter holding unit is mounted at the wall surface. Furthermore, the ventilation air assembly includes a filter, which is arranged in the housing of the filter holding unit such that the ventilation air passes through the filter when flowing through the housing from the inlet to the outlet. Furthermore, the ventilation air assembly includes a wall portion having a wall surface, and a heater device, such as a radiator, which is mounted at the wall surface. The filter holding unit and the heater device are such positioned relative each other and the wall surface, and the control member is such adjustable, that the ventilation air flow exiting the outlet is directed towards a space between the wall surface and the heater device. The embodiment of the present invention does also relate to a filter holding unit for use in such a ventilation air assembly. | 12-23-2010 |
| 454198000 | Condensation preventer | 1 |
| 20090270023 | Window condensation control - 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. | 10-29-2009 |

| 20120015596 | DRY OPEN WINDOW AND DRY WINDOW FAN, TWO DEVICES FOR KEEPING RAIN OUT OF OPEN WINDOWS OR OTHER OPENINGS BUT LET AIR FLOW THROUGH WINDOWS OR OTHER OPENINGS - 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. | 01-19-2012 |
| 20090186570 | Air Handling System - 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. | 07-23-2009 |
| 20110039490 | Window Fan - In the specification and drawings a window fan is described and shown. The window fan cools a room using outside air when the room air meets certain criteria relative to a set point and the outside air meets certain preselected criteria relative to the indoor air. The window fan may also exhaust room air to the outside when the room air meets certain criteria relative to a set point and the outside air meets certain preselected criteria relative to the indoor air | 02-17-2011 |

| 20090104867 | Building aperture mounted ventilation apparatus - A ventilation apparatus provides an intermediate space between a building window and the outside the building and provides means for controlling air flow to or from the intermediate space to or from the a building window and the outside of the building. The apparatus can be used in three modes: in one mode for heating air in the interior of the building structure by a circulating flow of air from inside the building, through the intermediate space where it is warmed by captured solar energy, and back into the building interior; in another mode for cooling the interior of the building structure by conveying warm interior air through the intermediate space to outside the building; and in another mode for allowing free two-way ventilation between the interior of the building structure, through the intermediate space, and to and from the outside air. | 04-23-2009 |

| 20100048123 | SYSTEM AND METHOD FOR ENERGY EFFICIENT AIR COOLING, EXCHANGE AND CIRCULATION - 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. | 02-25-2010 |

| 20100317281 | PTAC LOUVER - A PTAC louver assembly for glazing in a window wall which is field adjustable for fastening to a PTAC sleeves provided by different manufacturers. A unique system includes inwardly directed flanges which form a box within a box when mated to the PTAC sleeve. Sealant between the flanges and the PTAC sleeve provide a substantially water tight assembly. By sealing between the sleeve and the lower sill flange, the need to seal the sleeve face and to align weep holes in the PTAC sleeve is no longer necessary. Blank-off panels are filled with high temperature insulation which allows the louver system to be painted and baked after assembly. A unique louver blade assembly uses sliding retention bars with aligned notches to receive and capture louver blades using a clamping force. | 12-16-2010 |
