Definitions
- ABSTRACT Ventilation and air conditioning system for heating, cooling and ventilating existing buildings, which avoids the necessity of breaking through the walls, floor or ceiling of the building for the provision of air supply and exhaust ducts.
- This systems consists of an air-tight false building wall, which may be a false front wall of the building in the form of a subframe having air supply and return ducts therein having communication with the interior of the building.
- the breaking through of the walls, floors and ceilings of the building is avoided by placing at least one false wall along a wall of the building and spaced from the wall of the building and placing the air supply and return ducts in this false wall and connecting these ducts with a heating, ventilation or air conditioning system and at the same time, protecting the region of the building covered by the false wall from noise, dust and other undesirable emissions.
- a second wall which may a front wall
- a supply and exhaust channel network is formed in the space between the second front wall and the front wall of the building having air circulation and return ducts therein connected with air circulation and return units which may be air conditioning units which may also serve as heating units.
- Other air circulating ducts then lead into the building usually through the existing window openings or along the floor or ceiling of the building to circulate cool air into the building and to withdraw stale air therefrom.
- the air circulation and exhaust network can readily be installed along the original wall of the building prior to the building of the false wall and the false wall can be so constructed as to conform to the original wall and to give an architecturally satisfying appearance.
- forced air circulation boxes in the form of fans may be provided in communication with the ducts and are sufficient to provide the room with fresh air or with recirculated air, it being understood that the fresh air forced into the rooms forces the stale air out of the rooms to be exhausted through a channel network between the existing wall and false wall of the building.
- the air circulation ducts may have communication with the heating system which may be a part or in communication with the blowers or fans and where it is desired to cool and heat the building as well as humidify the supply of air in the building, the air circulating means may be in the form of reverse cycle air conditioners which may be used for both heating and cooling purposes.
- the air supply and return network may be used in connection with the original heating system installed in the building where such a system is in the building.
- the false wall provides an air and water-tight wall in the form of a subconstruction, which is braced against the building wall and having glass therein in the area of the building windows and connected with the frames for the building windows as well as the opposite end walls of the building and supporting pillars therefor to further strengthen the false wall and prevent dust, water and moisture from entering the spaces between the two walls.
- the advantages of the present invention besides providing a ventilation, heating and cooling system for a building, seal the wall of a building along which the false front extends and is readily and positively attached thereto.
- a further advantage of the invention is that air circulation or conditioning boxes may be arranged in the area of the window support of the building window to induce fresh air from above the building window generally parallel to the ceiling of the room and to extract stale air from along the bottom of the room along the window railings.
- the air supply channel network may be connected to an air conditioning system and the extraction channel network may be connected with suction devices such as suction fans and a mixing damper arrangement may be included for controlling the mixing of fresh air, warm air and cool air in the room.
- suction devices such as suction fans
- a mixing damper arrangement may be included for controlling the mixing of fresh air, warm air and cool air in the room.
- a further advantage of the invention is that by the construction of a false wall or front spaced from an already existing building wall, with the conditioners or blowers required for the ventilation or air conditioning of the room contained in the space between the wall of the building and the false wall outside of the building proper, the space between the building wall and false wall may be used for the air circulating network without obstructing or entailing costly structural changes in the building itself.
- a further advantage of the invention is that the false wall can be prefabricated and assembled without excessive personnel or time consumption with the false wall forming a protection from noise, dust and undesirable emissions.
- FIG. 1 is a schematic front view of a building structure diagrammatically illustrating a front wall of the building with a portion of a false wall spaced in advance of the front wall.
- FIG. 2 is a fragmentary diagrammatic vertical sectional view taken through the wall and window structure of a building illustrating the false wall of the invention spaced in advance of the original wall of the building.
- FIG. 3 is a horizontal sectional view taken through the window structure shown in FIG. 2;

- the air circulation space is diagrammatically illustrated as having ductwork extending in the area of pillars and railings 6 and including an air supply duct 3 illustrated by dot-dash lines contained within an air exhaust duct 4 illustrated by solid lines.
- an air supply duct 3 is shown as being circular in cross section and as extending within the exhaust duct 4, which is shown as being rectangular in cross section and between connecting frames 14 extending along the insides of the window frames and along opposite sides of the window frames.
- the air circulating and exhaust ducts 3 and 4 may be connected with supply and exhaust blowers re spectively (not shown) and extend vertically along the wall of the building from the bottom to the top thereof in the space between the false wall 2 and the original building wall 1.
- the supply ducts have communication with air cooling boxes 8 which are arranged between the pillars 5 and between pillars 5 and 12 for supplying cooled air to the room of the building along the tops of windows 7.
- the air cooling boxes 8 may be in the form of air distribution boxes and may have filters (not shown) therein, or may be in the form of air conditioners which either may be used for cooling purposes or may operate on reverse cycles for heating and dehumidifying purposes.
- the false wall 2 is air and water-tight providing a closed wall, which in many buildings may be a front wall and consisting of a subconstruction 9 spaced from the building wall 1 and suitably connected to and braced to said wall to provide a rigid wall construction.
- the false wall has a front panel in the area of the pillars 12 and 5 and railings 6 and has glass panels 11 in the area of the building windows 7 and in direct alignment therewith.
- the subconstruction 9 includes a series of connecting frames 14 which are of a rectangular duct-like form extending outwardly of the window opening of the building.
- Each connecting frame has an outwardly extending leg 14a extending at right angles to the side wall of the frame and having an outwardly opening recess 14b formed integrally therewith.
- a divider 140 extends outwardly along the recess 14b to a sealing and closure member 14d extending along the adjacent ends of the panel 10 and the glass 11 and forms a seal therefor.
- the frame 14 also has an opposite leg l4e spaced from a vertical leg of an angle iron generally conforming to an angle bracket 13 by a seal 13a.
- the angle iron 20 is spaced from the angle bracket 13 by sealing material 13b.
- the seals may be of plastic or rubber material.
- a bolt or screw 20a is provided to secure the angle irons together while a second bolt or screw 20b secures the leg Me of the frame 14 to the angle iron 20 and the angle bracket 13.
