AIR DISTRIBUTION SYSTEM ESPECIALLY FOR AIR CONDITIONERS DISTRIBUTIONSANORDNING FÖR LUFT, I SYNNERHET TILL LUFTKONDI-TIONERINGSANLÄGGNINGAR

This invention relates to a distribution system for air conditioners in buildings, comprising a duct system providing inlets for exhaust air located at least in some walls and / or floors of the building.

Background of the invention

The insulation of new houses has become better and better, resulting in lower energy and power requirements. This has led to the fact that the conventional heating system is oversized and thus unnecessarily expensive to procure and operate, which has led to demands for a cheaper heating system. For example, it is not economically defensible to install a water-borne heat system with heat pumps, for example at SEK 40,000, when the total heating costs do not exceed SEK 1,000 / year. There has therefore been a sharp increase in interest in air: for transferred heat (in any case the air must be heated)> and which, moreover, is already a perceived system for ventilation, which makes it seem natural to use this as well ... heat distribution in villas and the like. However, experiences with the air transfer system are poor for the following reasons.

1. Almost all systems are installed in the attic or outside the house's climate protection, meaning its well-insulated exterior walls and bulkheads, which has meant that insulation is significantly worse in ventilation ducts than ... in the house in general. In addition, there is a high risk of leakage in the joints.

'- 2. Conventional houses are forced to have airflows of 2 86325 and higher temperatures, which means higher transmission losses, higher leakage losses and higher noise.

3. Separate ventilation and heating systems mean that the ventilation air is cold, which causes draft. Houses with a ventilation heat exchanger always have a defroster and to avoid water, this defroster is almost always on at lower temperatures, which is why the heat exchanger is short-circuited and the system essentially takes more heat than gives back. This has given the system a bad reputation.

4. In order to save energy and reduce the moisture load on the walls, the houses are made more and more dense, mainly with a diffusion-tight plastic foil layer11a. It is essential that the house is dense. The current ventilation system means that several penetrations have to be made, in which case the new dif-f new layer often becomes leaky. The work is therefore subject to a very high accuracy requirement.

5. Internal ducting has so far posed a major aesthetic problem that has only been acceptable in exceptional cases. There are e.g. built in ducts with roof corners, which places special demands on design solutions. In addition, it has often brought with it unsuitable air conditioners.

: Purpose and Significance of the Invention

The object of the invention is to provide an air distribution system which is substantially located inside the "climate protection" of the house, so that the transmission losses are reduced, as well as ... the significance of leakage in the ducts Another object is to obtain a substantially free floor plan without aesthetic ducts and where a suitable equipment placement should be possible, this is obtained by the fact that the hollow beams and the hollow vertical beams are placed inside the outer thermal insulation of the building, '**. 1 kke and, forming

The invention will now be described in more detail with reference to the drawings, which show a few embodiments.

Figure 1 shows a section through the upper part of a partition wall with a partition in which the partition system according to the invention is placed in the partition wall.

Figure 2 shows a view analogous to Figure 1, but with two hollow beams superimposed.

Figure 3 shows a perspective view of the parts of the partition wall in two planes formed as hollow beams according to the invention.

Figure 4 shows a section through a beam plate with corresponding lat-; with tio, where a hollow beam is placed between the floor and the ^ / plate.

Figure 5 shows a section of a rafter beam or the like in which a hollow beam according to the invention is placed in connection with a roof covering.

Figure 6 shows a section of an outer wall in which a hollow beam is embedded in the inner surface of the outer wall.

The distribution system according to the invention consists of a hollow beam 11 or a hollow stop 12 connected to the structures of a building 4 86325, i. its walls 13 and / or bulkheads 14, 15. The hollow beams 11 or the vertical beams 12 are in principle so-called light beams or light vertical beams consisting of spaced-apart beams 16, for example timber of wood and double beams 17, e.g. The width of the box beam is best adapted to the thickness of the partition, while the height is determined partly by the load-bearing capacity of the beam and partly by the amounts of air that will flow through the inner duct 18 of the hollow beam per unit time.

The box beam thus forms an integral part of the wall structure and the opening for the inlet or outlet device 19, 20 and the heat exchanger unit 21 or the like can take place in the beam plate 17 as well as in its beams 16 without affecting its strength to a significant extent. In the event that additional sound attenuation is desired, the interior of the hollow beam may be coated with a sound absorbing and / or backing layer 22, e.g. consisting of a porous material coated with a film. , which expands under the influence of heat • * 'and protects the surface behind.

Figure 2 shows two hollow beams 11 arranged vertically superimposed on the same wall, preferably in the part of the wall adjacent to the upper bulkhead, and which hollow beams are intended for the supply and exhaust air ducts 23, 24.

: Figure 3 shows the invention fitted to a partition in a multi-storey building, in which the lower hollow beam 11 acts as a duct in the first floor plane while the upper hollow beam 'acts as a supply air duct in the second floor level. To divide the supply air: i between the floor levels, one or more • · I; 5 86325 wall vertical beams are made of hollow beams 12 connected to the upper and lower hollow beams 25, 26.

Depending on local conditions in the building, it may be desirable to place one or more boxes 1 under the floor covering 29, as in the embodiment shown in Figure 4, where the hollow beam also forms a base for the partition 30 on the floor 29, which in turn may include hollow vertical beams for air distribution.

Since hollow beams 11 and hollow vertical beams 12 are relatively inexpensive to manufacture, possibly all beams between the floor covering 29 and the bulkhead 15 can be made of hollow beams according to the invention which are connected at their ends to transverse hollow beams to give a heated floor. you 1mään.

It is advantageous if the whole air distribution system, i.e. all hollow beams and also 1heating 1aite and 1heat exchanger-aggregaa11i ·. : is located inside the well-insulated external walls and ... bulkheads of a building, but certain floor arrangements may make it necessary to place hollow beams in the bulkhead or; _ to the outer wall. Such examples are shown in Figures 5 and 6, in which Figure 5 the hollow beam 11 is placed horizontally in the device on the upper side of the roof panels 31 of the bulkhead 14. In the embodiment shown in Fig. 6, the hollow beam 11 is located directly below the actual upper band 32 of the outer wall inside the insulation 33.

. The invention is not limited to the embodiments shown and described, but many variations are conceivable. within the scope of the claims.
