The invention relates to a system for temperature-controlling rooms with a room ceiling or a room wall on which is suspended a structure of rails which run parallel to one another and form a lower rail plane running parallel to the room ceiling or an inner rail plane running parallel to the room wall, and between which a plurality of cooling or heating elements can be inserted.
Such a system is sold by the company Knauf, Iphofen under the name “RCS cooling/heating ceiling”. Suspended heating or cooling ceilings can have exactly the same design as conventional suspended ceilings. Copper or plastic pipes through which cold or warm water flows emit the temperature to metal pressed-on heat-conducting profiles. Plastic capillary tube mats can also be used instead of pipes (hoses). No heat-conducting plates are used in the case of capillary tube mats. It is very time-consuming to mount the cooling or heating elements (thermal boards) on the substructure. Cross connectors or anchor angles to which the thermal boards are screwed later need to be fastened to the rails.
A cooling ceiling construction, in which the heat exchanger elements made from metal are inserted between the rails which run in parallel, is known from DE 10 2013 021 054 A1. For this purpose, a specially configured profile into which the heat exchanger element is hooked and then pivoted between the rails and clamped there in the neighboring profile is first fastened on the rails. If the heat exchanger elements are all attached in the lower rail plane, gypsum plasterboard is screwed to the rails such that they bear against the heat exchanger elements. Here too, it is time-consuming to mount the ceiling because the heat exchanger elements are first fastened to the rails and only then can the special profiles be clamped on and the gypsum plasterboard then needs to be screwed on. Owing to the clamping, there is no defined position for the heat exchanger elements cooling or heating element) such that air gaps from the gypsum plasterboard cannot be excluded if work has not been performed with great care.
In EP 1 344 987 A2, premounted large-area heating and cooling elements, which consist of a thermal board, are proposed onto which spacers are glued in the edge region. Capillary tube mats are interposed between the spacers and covered with insulation. A covering film is laid over the insulation and fastened to the spacers. Through bores, via which the large-area heating and cooling element can be screwed to the ceiling substructure, are provided in the region of the spacers.
Starting from this prior art, the object of the invention is to improve the described system in such a way that the cooling or heating elements can be mounted easily.
In order to solve the problem, a generic system is characterized by a plurality of fixing elements by means of which the cooling or heating elements can be fixed with respect to the rails of the structure in a vertical or inward direction facing away from the room ceiling or room wall, respectively, and by a plurality of brackets which can be fastened on the rails and which force the cooling or heating elements, in a direction away from the room ceiling or room wall, into a plane which coincides at least with the lower/inner rail plane.
The cooling or heating elements are suspended from the structure via the fixing elements. The brackets which allow the cooling or heating elements to be at least flush with the rails ensure that the ceiling boards which are subsequently fastened on the rails lie flat on the cooling or heating elements and good heat transfer is possible. The brackets preferably press the cooling or heating elements beyond the lower/inner rail plane such that they project slightly above the rails and, when the ceiling boards are fastened, are pressed onto the surface of the boards counter to the force of the brackets such that it is ensured that no air bridge occurs which prevents the transfer of heat.
The fixing elements can preferably be fastened on the cooling or heating element so that they can pivot about a vertical axis. In order to mount the cooling or heating elements, the boards are pivoted toward the center of the elements, and the cooling or heating element is then inserted between the rails and the boards are then rotated over the outer edge so that they lie on the front side of the rails and the cooling or heating elements are supported on the rails. They can move toward the room ceiling.
The brackets are preferably designed in the form of strips and extend over the whole width of the cooling or heating elements such that the brackets can be hooked into the rails with their free ends. The brackets are in particular preferably designed so that they are springy at their free ends.
The cooling or heating elements preferably consist of a meandering pipe which is laid inside a polymer foam board and through which a cooling or heating fluid can flow. This fluid is preferably water. A pipe should be considered to be synonymous with a hose.
A cooling or heating element preferably consists of a board which has meandering channels which are open on the front side. The front side of the board, including the channels, is coated with an aluminum layer and the pipe is laid inside the channels.
It is advantageous if the aluminum layer is formed from at least one sheet. A plurality of sheets adjoining one another can also be used. The sheets are shaped such that they can be laid on top of the board and parts of the sheets then engage in the channels in order to cover the whole surface of the board.
The combination of the board, aluminum layer, and pipe can be screwed together by means of a plurality of clamps extending over the full width and arranged on both the front side and the rear side. The screws here pass through the clamps.
At least some of the clamps arranged on the front side can have the fixing elements such that there is no need for the fixing elements to be fastened separately. At least four fixing elements need to be provided per cooling or heating element.
An exemplary embodiment of the system according to the invention is explained below with the aid of drawings, in which:
The substructure 2 consists of rails, arranged transversely relative to each other, which are suspended on the room ceiling 1 via threaded rods 10 fastened to the rails 9. A plurality of cooling or heating elements 4 are inserted between the rails 3 which run parallel to one another. The cooling or heating elements 4 each consist of a polymer foam board 8, an aluminum layer 83 which consists of a plurality of sheets 83.1, 83.2, 83.3 adjoining one another and are screwed to one another via brackets 82.1, 84.1 arranged over the whole width B on the front side 82 and the rear side 84. The front side 82 of the board 8 is the functional side. It therefore faces the room when the cooling or heating elements are mounted. Meandering channels 81 are introduced into the front side of the board 8. The aluminum layer 83 has corresponding channels 86. A pipe or a hose 7, with a meandering shape, is correspondingly laid inside the channels. The pipe 7 is laid inside the board 8 such that the two free ends are led in and out at the same edge of the board 8 parallel to each other.
The rails 3 have a U-shaped design in cross-section, wherein the two vertical flanges 3a, 3b extend so that they are angled inward such that undercuts 3c are formed. A plurality of brackets 6 which, as shown in
The cooling or heating elements 4 can also be laid in the floor of the room or on the room walls. For installation in the floor, the boards 8 are laid on a sound insulation board and covered with screed or the like. Installation on a wall is similar to installation on a ceiling. The structure 2 is then designed so that it does not face downward and instead faces inward into the room.
