Heating. Ventilation. Cooling.

The functions described here are extremely economic under energetic points of view.

On the one hand the energy level necessary for the heating and the power demand are very low, on the other hand the supply air evenly flow through the entire room. Thus, the necessary aerial renewal is guaranteed.

The required heating performance is largely delivered by the radiant heat from the underfloor heating system. This has the effect of lowering the room temperature – compared to the heating by radiators – because the operative perceived temperature is regarded as comfortable. Because the supply air is in direct contact with the heating pipes, the system module works as a large scale heat exchanger, so that the inflowing air makes a contribution to the heating load. The most comfortable temperature profile in the room results in the arrangement of the outlets in front of the windows.

The distribution of supply air through the floor ducting and the system module has the distinctive advantage that the supply air channels are not visible once the screed has been laid. By the correct layout of supply air, spent air and overflow areas, the building is well ventilated. The air supply and distribution in the rooms is implemented to heat from the bottom floor to the top floor. This form of ventilation corresponds with the natural flow principle. Air and natural heat transport occur in the same direction.

In the event that cooling is required, cool water flows through the heating pipes. Here again the tempered floor area and fresh air make a contribution to the cooling load. In compliance with the comfort criteria the cooling load reduces too. The cooled supply air is drier and thus increases the comfort. The cooled supply air streams into the room through the outlets installed in the floor. Due to the increased circulation, the cooling performance of AIRCONOMY® is higher than simple underfloor cooling.
