DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The invention relates to a cooling ceiling for air conditioning a room with a system of pipes through which cooling water flows.
For known cooling ceilings (DE 39 21 710 A1), the pipes forming the heat exchanger element are inserted into a profiled rail, which, at its side directed to the bare ceiling, is suspended from the bare ceiling over a bearing rail, a longitudinal beam and a suspension strut and is connected at its underside over magnets with panels constructed as ceiling lining elements. This construction is expensive to build and there is little flexibility when it is used under tight space conditions.
SUMMARY OF THE INVENTION
It is an object of the invention to provide a cooling ceiling for room air conditioning of the cooling pipes which are placed stress-free on the ceiling elements and, in the event of different ceiling distances, makes it possible to compensate for permissible variations with little technical effort.
The present invention provides a cooling ceiling with a connecting element, for stress-free support of cooling pipes in an installed position and an installation of ceiling elements with an inner side having cooling water pipe sections for the heat exchange directed to the bare sealing, and which are adapted with little effort to different installation conditions. At the same time, a substructure, which is formed between the bare ceiling and the ceiling element, such as the holding element that is supported in the installed position at a beam, can be combined as a standard beam element with the ceiling element forming a standard panel part in such a manner, that adaptation even to tight space relationships takes place in each case with little effort over the connecting element. The ceiling element, which lies against the cooling pipe in the installed position utilizing vertical movement clearance, can be fixed at different installation heights.
With the connecting element, a component is provided for new constructions as well as for reconstructions of cooling ceilings. This component can be installed with little effort and without additional accessories. Furthermore, this component makes simple dismantling in the region of the cooling ceiling possible, for example, for repairs.
The development of the cooling ceiling with a molded plastic part as a connecting element, which preferably has the basic shape of a parallelepiped, provides a solid, non-damaging connection between the cooling pipes or cooling regions and the associated holding elements, which can easily be manufactured. In a preferred development with inwardly directed hook parts, the connecting elements, which are in two dimensional engagement with the cooling pipes and the holding elements, can be connected only in a position deviated from its installed position with a holding element and detached from this again, so that, after the connection with a cooling pipe is established, a connection with the holding elements is assured, which can be adjusted in height, but not, however, readily be undone.
Further details and advantages of the invention arise out of the following specification and the drawing, which illustrates several embodiments of an inventive cooling ceiling.
