Save heating costs in winter?
The specific gravity of heated air is less than that of cold air. Following the laws of physics, the warm air collects under the ceiling. A layer of heat is formed in the room. Anyone who has ever stood on a ladder to perform work on the ceiling knows the problem. The higher the room, the greater the temperature difference between the ceiling and the floor. This is where a lot of heating energy is wasted.
Foot-cold without ceiling fan
The higher a room, the stronger the effect: there is an immense temperature difference between the floor and ceiling. Fireplaces and tiles increase the effect even more. Important for the users of the room, however, is the temperature on the floor, because in extremes such as the füssen low temperatures are perceived as particularly unpleasant.
The problem:
The warm air collects under the ceiling, on the floor it is uncomfortably cold. The effect: cold feet, hot head. To achieve a comfortable temperature in the floor area, a lot of additional heating energy has to be used. In order to achieve a floor temperature of 21 degrees in the example shown above, up to 30% more heating energy must be used (based on experience, 1°C temperature increase means about 6% more heating energy).
A ceiling fan balances temperature
To bring the heat accumulated under the ceiling into the occupied area, there are several ways. One is to draw it in at the ceiling and üreintroduce it via a pipe system in the floor area. However, this is costly and not always possible due to the structural conditions. It goes better and cheaper:
The solutin:
The warm air accumulated under the ceiling is mixed with the cold air accumulated on the floor. This creates a pleasant mixed temperature throughout the room, without thisfür additional heating effort is nötig. The air velocity in the occupied zone is low (less than 0.2 m/sec.) due to the fan's reverse rotation and is therefore draft-free. Whether the ceiling fan must run forward or backward depends primarily on the room height.
For use in commercial areas, such as warehouses, production halls, tennis courts, and other halls, the TDA system is ideal. A fully automatic control with sensors on the ceiling and floor ensures that the fans are only in operation when it really makes sense.
In the private sector, decorative ceiling fans are also used, depending on the size and height of the room, to keep the heat cool. But not every ceiling fan is suitable for this purpose.
