with previously known metal facade walls and curtain walls, a room enclosure temperature that is perceived as comfortable is often not reached, but rather is significantly below or exceeded. A room is perceived as comfortable if its RaumumschlieSung Temperatur with practically still air is in the range of 20 ⁰ C. Most known facade walls and curtain walls usually comprise undivided metal construction or scaffolding parts from mostly vertical posts and scales right transom, which supports the facades or form curtain walls and have no or at least inadequate thermal resistance that affects the thermal insulation. Therefore the room temperature is im Area of such facade walls and curtain walls strongly dependent on the weather conditions and temperatures outside the building, as in winter their heat dissipation to the cold metal construction parts and in summer the heat absorption of the metal construction parts heated up by solar radiation may be considerable. If that The metal frame and its cladding are also darker, as has been more common in recent times Color is anodized or painted, then summer Room enclosure temperatures of 36 ° C and more No rarity

To overcome this problem, temperature control systems, so-called induction air conditioning systems, are known, which have a central temperature control system and in have an induction device in each room. The induction devices are connected to the central temperature control system via pipes, with a front and a Return for a heat-supplying means of transport, a supply and a return for a heat-dissipating means Means of transport and a supply line for primary air are required. These lines need to each induction device in each room separately. Such induction temperature control systems have the disadvantage that their construction is very complex,

so that their operation requires a lot of energy and that dirt in the individual rooms is constantly in the Space is whirled up. Another disadvantage is that the induction system reduces the temperature so-called radiation holes can hardly influence.

Such radiation holes are wall areas whose temperature differs very greatly from the average room temperature. Typical radiation holes can, for example, be glass window surfaces that (in summer) by exposure to the sun an additional

Allow the metal wall construction to heat up.

For the temperature control of external rooms of a building there is also an integrated device Façade elements known (DE-OS 26 21 186) in which a framework of hollow supports and hollow bars for Facade elements and window surfaces are provided, which flow in a fixed manner are connected to each other and a heat transfer fluid inside the framework between a

Lead forward and a reverse. This can cause cold baw. warm metal framework parts of the wall of a The room is temperature-controlled in a satisfactory manner, thus creating a comfortable climate inside the room will. In this temperature control device, however, it is disadvantageous that the metal frame of the wall one Must have flow path for the heat transport medium. Such temperature control devices are therefore can only be used if this is already used as a specified design factor when the building is being planned were intended. Subsequent installation in existing buildings without temperature control equipment is practical due to the already constructed metal wall scaffolding without a flow passage not possible anymore.

In another known device of this type (DE-OS 25 34 140) Lsi each have a convector tube arranged inside a hollow post The hollow post serves as an air duct, and the inside Flowing air absorbs the heat from the convector pipe. The tempered air emerges from a slot of the Hollow post.

With this known arrangement, the temperature control device should respond quickly to changes the flow temperature of the heat transfer fluid can be achieved. Have the convector pipes have a small cross-section and give their energy to them very quickly via convector fins air flowing past. In this way, the convector pipes are very quickly, e.g. B. within about two minutes, cooled down when the flow temperature is reduced. This is useful when e.g. B. the The room is suddenly entered by a large number of people who, due to their heat emission, enter the room heat, or z. B. even with sudden exposure to the sun.

It is essential in the known arrangement that the hollow posts as such in the heat transfer play a subordinate role, namely not being used for the regulation itself, but as a Grundlai '.system serve the temperature control portion takes over, which is outside the expected temperature fluctuation range Because it should be avoided that the temperature of large masses must be changed more frequently, which means that the heating system has a much greater inertia on control processes would address. In the known arrangement, there is an additional "heat coupling" between the Konvekforrohr and the hollow posts arranged around it only by the moving ones Air masses.

In contrast, the subject of the application is based on a completely different objective.

The object of the invention is to create a device for controlling the temperature of rooms in a building, which are not only designed integrally with new buildings, but also for existing ones Buildings can be retrofitted very inexpensively in a simple manner.

The inventive solution to this problem is in the characterizing part of claim 1 in conjunction indicated with the genus, while advantageous developments of this solution the subclaims can be found.

A major advantage of the device according to the invention is that it is suitable for the To absorb heat radiation from an already existing facade with metal elements, if this one; r is exposed to high outside temperature or solar radiation This makes it possible on the one hand to avoid undesirable heating of the rooms exposed to such heat effects and on the other hand, to transfer the resulting heat to a "cold" side of the same building and thus saving energy. Such a device should at the same time be able to withstand cool or cold weather. " cold weather conditions then accordingly

ίο low surface temperature of the existing facade metal elements to separate from the temperature of the rooms, so that a low wall temperature, which would require a correspondingly increased internal temperature in the rooms, is avoided.

Another important advantage of the invention is that the temperature control device in arranged a small distance in front of the frame parts and / or on the frame parts more or less can be applied because between the heat transfer profiles on the one hand and the framework surface facing these on the other hand both through thermal radiation as well as by heat convection or both a thermal coupling is established.

Finally, an advantage can be seen in the fact that, according to the invention, in a simple, inexpensive manner a satisfactory temperature control can be achieved even in buildings in which the temperature control device has only been installed afterwards, and without affecting the architectural design on the inside of the existing facade.

In addition, an advantage of the invention can be seen in the fact that when a comparatively small one is used Cross-section for the pipeline system only requires such a circulating amount of heat transfer fluid is that the temperature control of the rooms can be regulated with sufficient speed.

Although it is known per se (DE-AS 22 39 438), radiators on the inside of outer walls directly

• ω to be placed in front of these, however, in such cases additional heat-insulating elements are arranged between the radiators and the wall, provided that the The thermal resistance of the wall itself is not already very high

After all, it was known (DE-OS 18 11480), Arrange heating surfaces on the inside of the room boundary surfaces. However, this did not exist Intention to arrange the heating surfaces only and exclusively in front of scaffolding parts and with them in warmth to couple. Rather, these heating surfaces should radiate directly into the room. There was an arrangement the heating surfaces opposite the building opening, for example window surfaces, provided according to of the invention should just be avoided to a

Avoid covering the building opening. This known arrangement of heating surfaces r _"O Gebaudeöffnungen is only appropriate where it does not interfere when the building openings such as windows, to be taken in large part from the heating surfaces.

The Invention .g is explained below on the basis of exemplary embodiments described in more detail with reference to the drawing; it shows

F i g. 1 a a detail of an inventive Temperature control device in a horizontal section through a building wall,

Fig. Ib shows a further detail of an inventive Temperature control device with a wall mounting in a horizontal section through a building

wall, and

The area of the heat transfer profile part 51, which according to FIG. 1 is located farthest away from the tube area of the Tcmperierungseinrichlung, lies at a distance from the associated frame part 3, which is to be tempered. In this case, this area can rest more or less against the associated framework part 3, so that the heat is transferred during operation by conduction and / or by radiation coupling. In this case, the heat transfer from the t-facade structure I to the temperature control structure I can be used thermally by circulating the heating or cooling water from the sunny side to the shady side. This causes an indirect heat transfer from the warning to the cold side.

The horizontal section shown in Fig. Ib through the Building wall or facade 2 with glass panes 5 fastened therein illustrates one of Fig. La similar temperature control device 1, which also has a heat transfer profile part 51, which is located at a close distance from the associated framework part 3 or abut this framework part can. According to this embodiment, there are essentially the same advantages as in a Construction according to Fig. La achieved.

The horizontal section shown in Fig. Ic through a building wall or facade 2 shows a temperature control device according to the invention t with two double tubes, which are at a distance of to Arranged temperature-regulating vertical supports of the framework 3 and with respect to the framework parts to be temperature-regulated in are aligned in such a way that radiation coupling between the temperature control device during operation 1 and the associated framework parts 3 is formed.

The temperature control device 1 is constructed in the form of a pipeline system, which at IO in area of the flow 14 and return 15 of the pipe system of the temperature control device 1 on the building facade 2 is attached. Im illustrated in Fig. Ic Embodiment, the building facade consists of vertical supports one of supports and horizontal bars existing metal framework 3, which attaches double glass panes 5, with insulation profiles 6

to are provided between the glass panes 5 and the vertical supports. The vertical support in the area of the Fastening point 10 of the temperature control device can be an integral part of the building facade 2, such as shown in FIG. I, and also facade elements or glass panes 5 via insulation 12 attach.

The temperature control device 1 according to FIG contact-free with the assigned scaffolding parts at a distance of 50 mm, so that an optimal Radiation coupling between the active parts is given

The radiation coupling between the active parts is in the temperature control device according to FIG further supported by the formation of the line system in the form of double pipes 20 and 21 and one Radiation Z reflector part 23, which is formed in one piece with each double tube 20 or 21 and in cross section Has U-shape. The free legs of the U-shaped radiation J 'reflector part 23 have in the built-in

»State of the temperature control device 1 in the direction the frame parts to be tempered 3.

The width of the Sirahlungs / Retlektorteils 23 is dimensioned so that this is the width of the associated tempering frame part 3 corresponds.

Instead of the cross-sectionally U-shaped design of the radiation / reflector part 23, this can also be implemented in the Have a parabolic cross-section, with the individual tube or tubes 20, 21 in the region of the focal point of the Parabola lies or lie.
