[0001] The invention relates to and air-conditioning system for rooms.
[0002] It is an object of the present invention to provide an air-conditioning system for rooms, in particular, for living spaces, that operates effectively and can be installed cost-efficiently.
[0003] In accordance with the present invention, this is achieved in that a flat cooling element is arranged within a wall of the room.
[0004] Advantageously, such a cooling element, through which preferably a cooling medium flows, can be installed with relatively minimal additional expenditure in the walls of the room, for example, during construction of the building. Without taking up any of the useable space of the room, it is possible in this way to provide large cooling-effective surfaces in rooms.
[0005] For installing the cooling elements, the ceiling is particularly suitable. In this case, the rising hot air and the cold air dropping from the cool ceiling cause advantageously an intensive air circulation that is beneficial for air conditioning the room.
[0006] Expediently, the cooling element is embedded in the wall material near the surface of the wall. In a preferred embodiment of the invention, the cooling element is embedded in the plaster layer of the wall. For this purpose, a cooling element is particularly beneficial that is comprised of at least one pre-manufactured web of a flexible carrier mat and at least one flexible cooling pipe fastened on the carrier mat. For a pipe diameter of less than 6 mm and a mat thickness of less than 1 mm, such a cooling system can be positioned without problems within the plaster layer whose thickness is within the normal or conventional range of such layers.
[0007] Preferably, the carrier mat has penetrations like a screen and has in particular a net structure. Such a mat that is formed by a fabric or woven material or mesh is penetrated by the plaster material, and, in this way, a fixed connection can be realized between the plaster material and the base onto which the plaster is applied. Advantageously, the mat enhances, on the one hand, the attachment of the plaster on the base surface to which the plaster is applied while forming, on the other hand, a reinforcement that strengthens the plaster layer.
[0008] On the side that is facing away from the base to which the plaster is applied, the mat can be provided with projecting pin-shaped connecting elements that are preferably undercut and therefore can get hooked within the plaster.
[0009] In another embodiment of the invention, the cooling element is designed to be adhesively connected to or/and attached (tacked) to the base to which the plaster is applied or/and a precoat of plaster.
[0010] The cooling element, in particular, the carrier mat, can be pre-manufactured to be self-adhesive in that it is provided with an adhesive layer that is preferably covered by a protective film that can be removed on site. In this way, self-adhesive webs can be manufactured that are preferably wound to a roll and are removed or unwound from the roll for adhesively connecting them to the base to which the plaster is to be applied. At the ends of the ceiling, the carrier mat is simply cut and, optionally, a further web section is rolled out in the opposite direction wherein the flexible cooling pipe can be continued from web section to web section.
[0011] The attachment that is provided in addition to or as an alternative to the adhesive connection can be realized by nailing, wherein, for example, staple-shaped or bracket-shaped nail elements are shot by means of a staple gun or the like through the carrier mat into the base onto which the plaster is to be applied or into the precoat of plaster.
[0012] On the aforementioned web or carrier mat, two cooling pipes, for example, can be arranged parallel to one another wherein the cooling medium flows through the cooling pipes in opposite directions and wherein each cooling pipe is connected to a cooling medium supply and a cooling medium return. Because of the opposite flow of the cooling medium, a uniform heat removal is realized across the surface area of the cooling element.
[0013] The installation of further cooling pipes is possible. In particular in this case, it appears to be expedient to arrange the cooling pipes parallel and at a spacing to one another in order to enable at locations between the pipes a bonding of the plaster to the base to which it is to be applied and to provide in this way a stable plaster layer.
[0014] Cooling elements of several rooms can be connected by means of supply and return pipes installed within the building walls to a central cooling aggregate. The new cooling system according to the invention that enables the formation of large cooling surfaces also enables however the use of cooling energy reservoirs whose temperatures are only slightly below the desired target temperature of the room. The cooling energy reservoir can be, for example, a well or a flowing stream having a temperature of 20°. Also, the connection of the cooling element with a heat exchanger that is arranged in the ground is possible.
