Description

The present invention relates to a system for distributing supply air or recirculated air in buildings, in particular detached and terraced houses, using a hollow core plate forming the lower, intermediate or upper floor to form the air duct system.

The object of the invention is to simplify the construction of the air duct system compared to the placement of conventional sheet metal ducts, which have to be either embedded in a ground-10 floor or enclosed in room spaces. The system according to the invention is characterized in that the cavities of each hollow core slab supported at both ends of the slab are connected to each other by a transverse channel 15 inside the slab and that the transverse channels of two parallel hollow core slabs are connected preferably derived from the central region of the cavity tile and distributed from the region 20 of the cavity tile at any desired points to cover the need for ventilation or heating above and / or below the tile.

The cavity duct system according to the invention does not need to be insulated against heat or moisture, which is a measure to be performed on the sheet metal ducts 25.

The cavity ductwork is used in connection with ventilation or air heating. The cavity duct system is best suited for ventilation or air heating applications where the maximum temperature of the air introduced into the cavity duct system does not exceed + 30 ° C. This is because the tile would not form a radiant heater.

The invention will become more apparent from the following description and the accompanying drawings, in which Figure 1 shows a cavity slab seen from above 35, Figure 2 shows 2 63828 sections taken from Figure 1, point aa, Figure 3 shows a section taken from Figure 1, point bb, Figure 4 shows Figure 1 taken from Figure 1, point cc. section, Fig. 5 shows a section taken at point dd in Fig. 1, Fig. 6 shows a section taken at point ee in Fig. 1, Fig. 7 shows a section taken at point ff in Fig. 1 and Fig. 8 shows in principle a drawing of a system according to the invention,

Ductwork for conducting outdoor air to each room or space is formed by parallel cavity slabs 2 in which the cavities 3 are connected to adjacent cavities 3 and the cavities 3 of adjacent slabs 2 to each other so as to form a single air space - supply air cavity through which air can be distributed. 20 from anywhere.

The air space formed by the slab 1 allows the supply air (recirculation line) to be distributed to any desired destination, either to cover the need for ventilation or the need for heating on the top or bottom of the slab.

The hollow core slab 1 with a uniform air space can be made in the lower, upper or intermediate floor. It is essential that the required air duct system is formed simultaneously in connection with the installation of the tiles 2, and the slab 1 is utilized both as a load-bearing structure and as an air duct system.

All the cavities 3 of each hollow slab 2 are blocked at both ends as can be seen in Figure 3. The cavities 3 of each hollow slab 2 are connected to each other at at least one point by a transverse channel 4 inside the slab 4. Preferably such transverse channel 35 is located close to each end plate 2 . The transverse channels 4 are formed in the slab in connection with the manufacture of the slab. The transverse ducts 4 of the two parallel hollow core plates 2 must be aligned so that they can be connected to each other into a single air duct system. The connection can be assisted by a connecting pipe 5 which is installed between the hollow core plates 2, whereby the transverse channel 4 is not blocked when filling the joint between the hollow core plates 2.

The supply air is preferably led to the middle of the hollow core plate 1, as shown in Figures 1 and 4.

10 From this connection 5, the supply air flows everywhere in a uniform air duct system 3, 4 ,. from which it can be Distributed to any desired object above and / or below the slab 1. The air distribution through the outlet opening 6 above the plate 1 is illustrated in Figures 1 and 5 and through the opening 7 15 below the plate 1 in Figures 1 and 6.

Figure 8 is a schematic diagram of the system. It shows an active solar radiation collector 8, a heat recovery device 9, a hollow slab 1 forming a massive subfloor structure of a building and a heating and inlet 20 air device 10.
