Bernhard HUMBERT, 21 DAIX, rue de Fontaine 18 (France) "Device for heating or cooling rooms"

The invention falls in the field of heating and cooling (Air conditioning) with pulsating air for all areas of the House and industrial supplies.

In the field of air heating, three different methods are used according to the prior art, namely - heating with "fresh air", with "circulating air" or with "mixed air". In the case of fresh air heating, only air brought in from the outside is used, which is expelled again after it has given off heat to the room to be heated. Here acts

it is a not very economical heating system Heating with circulating air, the same air is always kept in circulation in pipes and radiators without that fresh air is supplied. Mixed air heating is a combination of the two former method, with some of the air after Heat dissipated back into the room, while the other part in the natural ventilation process with fresh air is replaced.

For example, an air circulation device has been proposed for heating a residential building, in which the warm air generated by a corresponding device rises in a vertical, central channel. At the level of the individual floors, this air is directed into horizontal pipes, from which it is blown into cavities provided under the floors and in the ceilings of the various apartments, for which purpose suitable control slides are provided. After flowing through these cavities, the air is again guided back to its generating device through cavities in the outer walls, which are provided with additional walls for this purpose.

The difficulties of such a heating system are that the floors are used as radiation surfaces. On the other hand, with systems of this type it is practically impossible to achieve a heat distribution according to the given requirements, i.e. either a substantially uniform temperature in all rooms or different temperatures depending on the space requirements, such as in living rooms, bedrooms and bathrooms, kitchens, hallways d

In contrast, the advantage is known for a uniform Heat distribution in the rooms with radiant heaters vertically distributed on the walls exposed to the cold outside is attainable.

The present invention relates to an air circulation heating system in a residential building, in which the above-mentioned advantage is offered, with the floor as a heat source associated disadvantages are eliminated.

The term "residential building" here means any type of space, apartment, empty room, etc. that has its own Heating system is provided.

while the outlet line 23 extends along the other side wall 32.

The inlet lines 21 are with the nozzles 210 to 214, the inlet lines 22 with the nozzles 220 to 225 and the Outlet line 2 3 is also provided with nozzles 231 to 234. The nozzles in the exit lines are used for blowing in the air at the level of the floor 33 into the walls 29 and 30 and the walls 35 on these walls on the one hand and in the lateral double wall 31, 36 on the other hand. The blown air rises in the direction of the arrows f ^ (Fig. 5) in the walls 29, 30 and 31 upwards and flows through at the level of the ceiling 37, the cavities, which are formed by the suspended ceiling 38, in the longitudinal direction of the building and is after entry into the cavities of the lateral double wall 32, 39 through the nozzles to 234 (FIG. 4) in the outlet line 23.

As shown in Fig. 4, the partition 66 divides the house into two separate living units, each through the Exit lines 21 and 22 are supplied and contain a different number of Einzelrätuaen. In the illustrated For example, the rooms 40 and 41 are replaced by the

- 11 -

109840/115 4

Entry line 21 and rooms 42 to 45 through the entry line 22 supplied. The individual rooms are divided with the help of partitions 46 and 47, which also a subdivision of the air circulation hollow spaces for the hot air effect in the walls; they extend over the entire width of the room from the partition 66 to the outer walls 29 and 30 and penetrate the additional double walls of the latter.

This creates a subdivided warm air circulation for the individual rooms created from the entry line, which the respective outer wall supplied and which is provided with one or more air nozzles per room.

All nozzles are preferably equipped with adjustable closure devices. Fig. 6 shows a nozzle with a number of rectangular and parallel to each other arranged% butterfly valves whose surface until the last flap 49 is from the first flap 46 against the flow direction of the air in the inlet line 21 gradually smaller.

The flaps are at their upper edges in the side walls of the Nozzle 210 and rotatable or pivotable at various points on its side edges in a horizontal metal rod 50

attached and can with the help of an actuator acting, for example, on the first flap U6 in different inclinations relative to the horizontal are moved. This actuator consists of a rod 51 which is hinged on the one hand to the flap 46 in the middle and on the other hand to the lever 52 of a crank is, the axis 5 3 of which is mounted in corresponding bores in the side walls of the nozzle 210. To open of the flaps, the crank can be turned from the outside in the direction of the arrow f ". The flaps are used to close pivoted together with the rod 50 in a horizontal position, the advantages of such a device are obvious. Since the surface of the flaps increases in the direction of the air flow, the impacting air always finds passage, no matter in which position the flaps may be in the inlet line, so that a noticeable reduction the draft losses and an economical ventilation are given.

The apartments above the unit 100 can be provided with their own heating system, their distribution circuit and T-shaped Connection cables are laid under the floor, while the heater and fan are in one room.

Such a system is identical in all parts to that in the ground floor apartment 100.

In Fig. 7 and 8 two air guidance systems are shown, which are used for better warm air distribution within the double walls and an improved heat transfer between the air flowing around the walls and the rooms to be heated. Λ

The guidance system in Fig. 7 consists of a number of strips 55 and 56, which are provided with the holes 54 and are arranged in parallel horizontal planes, and the double-walled cavity fill in its full width. The middle strips 55 are in one piece and the outer strips 56 are in two parts executed. They extend over the width of the room that they are between the partitions 4-6 and 47 only partially cover. The one-piece lasts take the

Center of the respective wall, while the two-part strips from opposite points of the partition walls jump forward *

By installing these strips, the air circulation in the walls takes place in a horizontal plane, whereby the in the The holes 54 also have a vertical air

Flow component is given.

The simple guidance system in Fig. 8 also consists of laterally arranged strips that are offset from the partition walls protrude and only partially overlap in the width of the room. These strips are used to create

C-

perforated in a vertical air stream. The side and middle strips are interrupted at the window openings, i.e. the lateral ends are at a certain distance from the window frame and the middle ones are in two Pieces divided on both sides of the window,

The actuation of the adjustable nozzle closures can of course instead of by hand, they can also be carried out automatically with electrical or pneumatic aids and by one or several thermostats are controlled, which are arranged in the room or rooms to be heated or cooled will.

Aids for insulation and thermal insulation to the outside are not shown in the figures in the accompanying drawing been. It is clear that the known technology of thermal insulation can be used wherever it is
