with the aquatherm-climasystem

An individual´s comfort and efficiency directly depend on the basic environmental conditions of his surroundings. Working efficiency varies according to temperature with every cooling degree.

Incorrect controlled room temperature, noise interference or draught are responsible for inefficient room conditions and therefore unsatisfactory performances. In offices, commercial premises, meeting rooms, etc., aquatherm pipe grids have become increasingly more popular for heating and cooling of ceilings and walls.

The ingenious aquatherm climasystem delivers pleasant room conditions without noise and forced air movement. With this technology cooling or heating is simply controllable.

Automatic designed change-over of heated or chilled water completes this system; allowing for individual room control within a building management system.

aquatherm-climasystem – due to its compact dimensions within – fits under the plaster or the dry-lined wall. Construction thickness including manifolds, mounting with the aquatherm-climasystemrail and connections amounts to only 24.5 mm.

The pipe grids have rectangular manifolds, which can be interlinked.

This allows an easy connection e.g. according to the reverse return principle (Tichelmann). The water volume for the required thermal output is distributed via square pipes (12 mm/25m pipe per m2) within the grids.

The velocity of flow and the pressure drop are minimized. Velocity of flow for a surface area of approx. 10 m2 is below 0.3 m/s.

The aquatherm climasystem can be installed, in the case of suspended ceilings, in tile size modules, dry construction behind gypsum wall board

or wet construction, embedded in wall and covered with plaster.

Even stud framed walls with gypsum board finishes are not a problem.

The low weight of only 2.5 kg/m2 (incl. water filling) does not effect the design of the ceiling element construction. The ceiling elements should include 30 mm of fibre glass insulation. Depending on their design, the pipe grids are connected by means of thermal welding or by pushfit couplings, and connected to the cooling- and heating water circuits.

The effect of the aquatherm-climasystems is to heat or cool the surface

of wall or ceiling it is installed behind by a few degrees below or above the ambient temperature. By radiation exchange with the surfaces, temperatures of the room and furnishings change. In a ceiling 60 % of the total heat transfer is achieved through ceiling radiation and 40 % through convection. The heat transfer rate is determined by the difference between ambient temperature and average surface temperature – high difference – high heat transfer.

Within a suspended ceiling system, the extend of aquatherm-climasystem installation will be governed by heating and cooling requirements.
