Thermoactive Component systems have been used for a long time for heating and cooling of office buildings. Increasingly, they are also used in private housing. In particular, the cooling in the summer months is at the forefront. By a conventional air conditioner is often not achieved the desired comfort.

How do these components?
The components are water-carrying pipes which are installed in the ceiling, similar to a floor heating. The concrete floor is used to thermally active area. An efficient heating and cooling is possible.
The building owner of this system is not always easy. Often, even the old ceiling heaters in the sixties are present. At that time, the ceiling is heated extremely strong with supply temperatures of 50 ° C. This led to headaches and other problems. Users of the rooms felt unwell. The true today but not anymore.
cooling
The warm air rises and collects at the ceiling of the floor. The concrete floor is heated the (convection). Through the pipeline system cool water flows from 18 to 20 ° C. The concrete is delivered to heat the water. It warms to 23 to 25 ° C. Thus, excess heat is removed from the component and it can absorb heat during the day again. The heat removed is deposited on the heat pump in the ground probe.
could of course also be cooled on the floor (floor heating). This leads to uncomfortable cold feet. Colds and discomfort are the result.
heating
with a flow temperature of max. 30 ° C, the water flows through the pipeline system and produces a surface temperature of 21-23 ° C. The adjustment is done room by room with electric thermostat valves.
Logically, only the ceiling upstairs is equipped with thermo active components. In a single-family house would never caused such a large accumulation of heat in large offices with x-times more people and computers. Through the steps and air spaces results in a continuous air exchange. The warm air is not jammed in each Gechossen.
construction
The tubes are mounted on a steel grid. This network is used the tubes as protection from damage. So they are easily accessible. The steel mesh has basically no structural function, but at lower
floor cross sections as part of the Oberarmierung be used. There is also the possibility of a sandwich construction, the pipe is provided here below and above with a steel grid, which provides optimum protection. However, this is a question of price.

+ free choice of floor covering
+ Minergie fit
+ economical and energy efficient
+ applicable in all types of buildings
disadvantages
- free component surface (eg, no acoustic elements)
- solid slab - Be careful when mounting of lights or other objects
- permanently installed system can be repaired only with great effort at damage
Retrofitting of thermo-active building systems
The optimum solution is to move the components in the concrete ceiling. Since this is for alterations and renovations is not possible, they can also use a ceiling element "overhead" are mounted on the concrete floor. These elements can cool or heat, they are sound absorbing and can be equipped with a sprinkler system as required. It is also possible for an existing ceiling heating from the sixties re use. Condition is of course always that other measures such as improving the building envelope are made. Home technology is not enough.
principle, it would also be possible to put this system on the walls, but the is not in housing, as the furnishing of these rooms would be nearly impossible.
