The invention relates to a device for heating and/or cooling buildings, such as residential or office. The device comprises a carrier plate, on which rests on passing Talon what about hydraulic binders with high thermal conductivity.

Such devices are known. For example, in the United Kingdom patent GB 2035435 or patent Austria AT 381160 IN the described device, in which the flat bearing plates are thickened, the outer lateral surface of which is formed passing vertically to the upper side of the base plate forming. When this pipe is leaking coolant or refrigerant is laid between thickening.

German patent DE 3300607 C2 relates to a liquid flat device for under floor heating, permit the passage of personnel during its installation, and heating pipes are laid in a seamless floors, which provides concave channels, which laid the pipe to protect it from possible damage and change positions.

In known from UK patent 2035435 And the solution placed between the thickening of the tube are covered with a relatively thick layer of adhesive and then are stuck flooring. Thus the space between the pipes and flooring will be partially filled.

In the device in accordance with AT 381160 IN thickening only blocked, and remain cavity through which may pass through the air.

From AT 403396 IN a device of the aforementioned type, in which tegevuse astringent hydraulic means. The ribs of the carrier plate and sealing the pipe is covered with a layer of plaster with high conductivity, with the side walls of the ribs of the base plate are, except for the curves in the lower and upper parts, perpendicular to the upper side of the carrier plate. As the width of the ribs defines a gap between the pipes, as a rule, are relatively wide areas, which is only a thin conductive layer of plaster on the edges of the insulating carrier plate. This leads to the fact that recourse to the heated indoor side of the device are formed of strips of different temperature and time are displayed on the surface of the wall or ceiling. Depending on local conditions, the temperature difference can be severaloWith that in the operating mode "heating" leads to uneven thermal emission and accumulation of contaminants on the surface of walls and ceiling, and in the operating mode "cooling" creates additional conditions for condensation on the surface of the walls.

The basis of the invention is to eliminate in a device of the above disadvantages of the prior art, in particular to provide a high speed control system when the minimum flow is surface side, facing the room, which is heated or cooled.

The proposed solution creates the advantage that filled the hardened hydraulic astringent depression carrier plate employed in a very large part of the surface of this astringent. As a consequence, a very uniform distribution of heat and the surface temperature of the device to its converted to a heated room side with a drop of only 0.2-0.3oWith, that is an order of magnitude smaller than according to the prior art. In addition, the device according to the invention differs less accumulation of heat, therefore there is the possibility of speeding up the adjustment and prevent the formation of condensation on the surface. Another advantage is the ease of installation on site, in particular in the installation of the device on the ground.

This has implications for the economic use of buildings with a low energy level, and also for buildings heated often only a few hours per day, such as schools, kindergartens, churches, cottages, etc.

The invention is illustrated with the help shown in the drawings, the example run.


in Fig. 4 is a top view of a carrier plate according to Fig. 1.

The device according to the invention consists of a carrier plate 1 of poorly conducts heat and sound material, for example of pressed fibrous material, for example from hemp. To do this, instead of hemp can be used with success also mineral fibrous materials, foams, etc.

This carrier plate 1 has on one side a wavy profile in the form preferably of rounded protrusions 1A and depressions 1b. The protrusions 1A are the angles at the apex of about 30o. The angles at the vertex can have a different value, but is less than 45o. The protrusions 1A and depression 1b preferably have a rounded cross-section in order to avoid the formation of cracks due to temperature changes in the applied thin layer 11 of plaster.

On the site of the depressions 1b is provided in the pipe 5, through which passes a coolant or cooling medium and which is arranged in heat-conductive layer 7 made of a material with high heat conductivity, for example of hardened hydraulic binders. The heat-conducting layer 7 may consist, for example, mortar, screed, a layer of concrete or plaster, which can be Smela, so, on the one hand, ensured the rapid operation of the device and, on the other hand, was possible effective temperature control. Thus the temperature difference on the surface of the ceiling and walls between the projections 1A and depressions 1b of the carrier plate 1 when the pipe diameter of 5-8 mm and between about 60 mm is only 0,2-0,3oWith compared to 3.2oIn the case of a flat carrier plate at equal intervals between the pipe and the same dimensions.

In an embodiment in accordance with Fig. 1 such heat-conductive layer 7 fills only the depression 1b of the carrier plate 1. On the side facing the heated or cooled to the room, in this embodiment, the provided cover plate 10 of the heat-conducting material, for example metal, which is connected with the layer 7 and the projections 1A of the carrier plate 1 with ensuring good heat transfer.

In the variant in accordance with Fig. 2 shows that the heat-conducting layer 7 covers the upper side of the projections 2 of the base plate 1. This layer 7 is covered with, for example, fiberglass 9, etc. and deposited layer 11 of plaster.

Suitable fiberglass 9 to put on the still wet layer 7 and the ve relatively small angle at the vertex of the profile and with large gaps between the tubes 5 of the upper side of the projections 1a of the carrier plate 1, made of insulating material, form only a narrow strip, facing the indoor side of the device creates a uniform temperature.

In the 2 holes in the carrier plate set of fixing means such as dowels 8, and thus the carrier plate 1 is mounted on the wall.

Mount the carrier on the support plate 1 can be realized, as shown in Fig. 3, using the element for mounting on the ceiling so that the fluent material to the subfloor is concrete or stucco flow through the holes 3 in the back and fill the wavy profile of the carrier plate, and at the same time they surround and fill pipe 5. For manufacturing such an option it is advisable to use a wooden casing 12 and so on , which is placed on the projections 1A of the carrier plate 1 and after hardening of concrete or similar will be removed and replaced from the room side plate 10. Instead of the protective plate 10 can be applied, for example, a thin layer 11 of plaster. Laid in the concrete ceiling mesh marked position 6.

The carrier plate 1 shown in Fig. 4. This bearing plate from a material with low heat conductivity provided with mounting holes, i.e. holes 2 for crematory passes the coolant or cooling medium, laid on the carrier plate 1 is preferably spirally and are in fluid concrete, plaster, etc. so that they do not touch the bottom of the depressions 1b, which are placed on the carrier plate 1 with gaps between the ribs 4. The ribs 4 can have points of inflection of the pipe 5 in addition to the vertical grooves horizontal grooves for knee rotation.

The carrier plate 1 pre-made from a fibrous material, for example from hemp or mineral wool, etc. or foam and is equipped at the factory pipes are rigidly arranged in the rib 4. This bearing plate may be provided with a pipe 5 along the entire height and/or width or depending on conditions only partially. The carrier plate 1 can on all four sides to unite in large registers of pipes with other similar bearing plates, and pipe 5 passes through the grooves 1C to the adjacent bearing plates or respectively to inlet and outlet pipes. Made thus registers pipes can be fitted to walls and/or ceilings, and floors with a device for heating and cooling according to the invention.

Of course, the invention is not limited to the described example. For example, instead of pipes 5, PI combination of those and other, or for special purposes, to establish the piezoelectric elements, etc.
