Description

Concrete core temperature control modules

The invention relates to a concrete core temperature control module with pipes laid and fixed in a meandering manner on a structural steel mat or the like.

Concrete core temperature control modules have already been proposed to achieve building temperature control. In these, pipes, for example made of plastic or metal, are laid in a meandering pattern on a structural steel mat or similar, through which a fluid heating or cooling agent, in the simplest case water, flows. The known concrete core temperature control modules are generally laid in such a way that the pipes are laid with a fixed laying distance and 180° deflection.

This familiar pipe laying means that pipes with decreasing or increasing temperatures are always next to each other, resulting in a continuously changing temperature profile from the flow side to the opposite end of the meander, which can have a very significant impact depending on the size of the module. The heating or cooling of the cooling or cooling medium is greater in the areas where the heating or cooling medium enters the surface to be tempered than in the areas that are a greater distance from the entry point of the surface to be tempered due to the continuous pipe laying. In the design case, the temperature differences can be 3°C for cooling and even up to 15 ^° C for heating. This affects the comfort in the room, which can only be guaranteed with as uniform a temperature profile as possible.

The invention is therefore based on the object of designing a concrete core temperature control module of the type mentioned at the outset in such a way that a uniform temperature profile is obtained over the entire mat while at the same time the pipe coil is easily returned to a return line located next to the flow line.

To achieve this object, the invention provides that the pipes are laid as double meanders, with the single meanders laid at varying distances interlocking. The arrangement is preferably designed in such a way that the laying distance between adjacent pipes of a single meander is alternately tripled, since when laying the second single meander leading back to the flow line, the laying distances between the pipes of one and the other meander are then identical. This in turn means that the pipes of the second meander that are already the most cooled or heated are arranged next to the particularly warm or cool pipes of the first meander leading in, so that overall compensation is achieved across the surface in such a way that an equal temperature supply or removal is guaranteed on average across the individual surface areas.
Another advantage is that the average temperature between the flow and the return is essentially constant.

Furthermore, a much greater uniformity of the distances between the flow and the return can be achieved.

A further advantage is that there is a uniform temperature distribution on the top or bottom of the building elements to be tempered, such as the ceilings of buildings, which can be adjusted via the installation distance between the supply and return lines.

Further advantages, features and details of the invention emerge from the following description of an embodiment and from the drawing, which shows a plan view of a concrete core temperature control module according to the invention.

A double meander according to the invention made of heating or cooling pipes, which are provided with a flow 5 and a return 6, is laid on a structural steel mat 1 made of intersecting longitudinal bars 2 and transverse bars 3. The individual turns of the interlocking individual meanders change from a single laying distance to a triple laying distance, etc.

The first meander turn containing the lead 5 is laid at a threefold distance, followed by a turn at a single meander distance and so on. After the

The last single-spaced turn is followed by a first turn of the counter-rotating single meander, laid at a distance of three times, which is led back to the feed point and ends as return line 6.

It is advisable to choose a single meander spacing that is the same as the grid of the structural steel mesh, but this design is ultimately not absolutely necessary. The advantages of a more uniform temperature profile according to the invention naturally also arise with completely different installation spacings.

However, the manufacture and connection of the pipes to the reinforcing steel mesh is simplified with this option. The dimensions of a concrete core tempering module can vary in width and length depending on the installation spacing.
