Another Polish patent application, number P.389227 , describes a ventilation system, specifically for use in residential and office buildings, wherein a header is installed inside a ventilation duct, said header being provided with two inlets (upper and lower) and one outlet and a tiltable damper inside the header. The upper and lower inlets are positioned in relation to each other at an angle of between 0° and 180°. The header comprises upper housing having an upper cover with an upper flanged inlet opening and having a lower opening to which a lower housing is attached detachably, said lower housing having a lower cover with a lower flanged inlet opening. The damper is mounted inside the header housing between the upper inlet opening and the lower inlet opening, wherein the outer contour of the damper matches the inner contour of the thermal housing.
The Polish patent specification PL174218 describes a ventilation element for installing in an opening in an outer wall of a building, specifically of an electrical switchroom. The disclosed element is provided with a set of parallel horizontal perforated panels mounted between vertical side walls of the element housing, said side walls preferably made of steel channel sections, and with a set of shield panels, wherein each shield panel, positioned diagonally between the perforated panels and provided with a closing damper attached thereto pivotably, consists of a flat part and vertical ribs attached thereto on both its sides. The rib positioned on the edge of the upper side of the panel is provided in the area of its connection with the flat part of the panel with a shoulder that forms a support for the horizontal perforated panel, and with a tubular pressing component positioned above the shoulder at a distance q equal to the thickness of the perforated panel, and with a horizontal lip above the pressing component. In the space between the lip and the pressing component is a pocket for connecting the closing damper mounted pivotably under the flat part of the shield panel. To this end the rib positioned on the edge of the upper side of the panel is provided with a key for pivotably mounting the closing damper thereon, said key being positioned under the flat part of the panel. The vertical rib positioned on the edge of the lower side of the panel is provided with a tubular pressing component positioned immediately under the flat part of this panel and with a horizontal lip at distance q below the pressing component, said lip constituting an opposite support for the horizontal perforated panel. The shield panel of the ventilation element according to that invention is preferably inclined at an angle of ca. 30° to the horizontal. The tubular pressing component designed to clamp the horizontal perforated panel is provided with a gap which is parallel to the axis of the pressing component, the edges of the gap forming preferably a central angle of 60°, and is preferably coupled with the rib of the shield panel by means of a shackle. The inner opening of the pressing component forms a seat for receiving a connector that fastens the pressing component to the side wall of the ventilation element housing. The lower shield panel is provided at its lower edge with a tubular pressing component positioned immediately below the flat part of the panel, and with a short, oriented downward rib terminated with a horizontal lip that forms support for the horizontal lower panel constituting part of the ventilation element housing. The housing of the ventilation element according to the invention is provided with a lower horizontal panel, comprising a flat part, supported on one side on the lip of the short rib of the lower shield panel, and provided near its edge with an angle bar connected to a vertical shield perpendicular thereto, said bar forming a drip edge. On the other side the lower horizontal panel is connected by means of the tubular pressing component with a short vertical rib.
In an alternative design, the rib of the lower shield panel is provided in its upper part with a lip of U-shaped cross section forming a seat in which the lip of a drip trough is clamped, wherein the front wall of the trough extends above the edge of the lip. The housing of the ventilation element according to the invention is also provided with an upper horizontal panel, comprising a flat part connected on one side by means of a tubular pressing component to a rib set on the upper edge of a vertical shelf of the side wall and set on the other side in a gap between the horizontal shoulder of the rib of the upper shield panel and the pressing element of that rib. The rib of the upper horizontal panel of the housing comprises a vertical part coupled by means of a shackle with a cap set on the edge of the vertical shelf of the side wall of the housing and provided with an inclined shelf constituting a drip edge. The closing damper of the ventilation element according to the invention comprises a flat part terminating on one side at the point of connection with the inclined shield panel with a cylindrical rim, said rim mating with the key of the lower part of the rib of this shield panel, said flat part provided on the other side with a straight lip inclined at right angle, onto which a flexible bolster is set, said bolster mating with the clamp seat formed between the horizontal lip and the pressing component of the rib. The housing of the ventilation element according to the invention is provided with side walls, the vertical shelves of which are fitted with detachable assembly and reinforcing strips with vertical ribs of shield panels mounted onto them. The shield panels and horizontal panels of the housing, as well as the closing dampers of the ventilation element according to the invention are preferably made of an aluminium alloy.
The ventilation system according to the invention comprises flexible ventilation ducts arranged in a subgrade, for instance in a concrete subgrade, said ducts connecting manifolds to the plenum boxes installed in the rooms of the building. Modular plenum boxes according to the invention and at least two modular air manifolds are installed in the run of flexible ventilation ducts consisting of sections of flexible tubes. The core of the modular design of the air manifolds and/or the plenum boxes consists in that both the basic module and the segment module are in the form of a rectangular box the shorter side walls of which are provided with openings for supply and exhaust connections, whereas on the longer sides of the module boxes, near their upper and lower edges, bolts are located near one of the edges and gaps for receiving the bolts of adjacent box and/or of capping cover are located near the opposite edge. Openings for receiving connector pipes in both the shorter side walls of the boxes as well as in the capping covers are dephased to enable bayonet mounting of the connector pipes in the openings by rotating them by half a turn. Each of the openings in side walls, when there is no need to attach a supply or exhaust connector pipe thereto, may be blanked with a cap mounted in the same manner as the connector pipe by rotating it by half a turn. The upper wall of the basic module is provided with an opening, preferably dephased, for connecting thereto an exhaust connector pipe of larger diameter than that of connector pipes attached to side walls of the box modules. The thus fabricated box module is assembled with another segment module of lower width to create a multichannel module. In specific embodiments, the supply and exhaust connector pipes may be attached to the openings in box modules by means of screw joints or snap connections or may be fastened permanently to the boxes.
The thus disclosed fittings of modular design may be assembled to form manifolds or plenum boxes with any number of connector pipes, that is inlets/outlets to ventilation ducts. The described system of fittings, supplemented with flexible ventilation ducts of any cross section shape, oval, round or rectangular, enables assembling any, even the most complex, ventilation system in single-family houses, office buildings, commercial buildings, industrial buildings or public buildings.
