The principle of cooling ceiling

A ceiling cooling is a pipe system, which is installed under the ceilings.

This can be compared with a heating element below the ceiling - with the difference that the cooling ceiling does not transfer heat to the room, it cools the room.

"Cold" water with a temperature around 16 ° C flows through a pipe system, thus the surface temperature of the ceiling is a few degrees below room temperature.  

All warmer surfaces like for example walls and windows, emanating equipment and people, dispense heat to the cold ceiling.

The water which flows through the pipe system affiliates and conducts the heat. That creates a comfortable room climate.

For those who need a level head - the thermal comfort

Chilled ceilings are particularly well suited to create a pleasant indoor climate.

With conventional air conditioners, heat is conducted from the room by convection i. e. through the air.

In contrast, the chilled ceiling cooling load is dissipated from the room by radiation.

Exceeding allowable air velocities is impossible with the cooling ceiling system.

A unpleasant air draft, which arises with a usual air conditioning, does not occurs with the use of chilled ceilings.

The operative temperature is composed of the mean surface temperature of the enclosed components of a room and the indoor air temperature.

By the use of chilled ceilings the surface temperature of the ceiling (radiant temperature) is slightly lowered as the air temperature.

Thus the indoor air temperature can be select up to 3°C higher as the temperature of an only air system with the same perceived temperature.

Scientific studies have shown that mental performance highly depends on the room temperature.

The best mental performance is achieved at a temperature around 23 ° C.

A temperature rise of 3K already reduced the mental capacity about 13% and with an increase of 5K it is 22%.

Chilled ceiling systems create a climate which enhances subjective well-being and objective supports mental performance.
