One Technique for two Functions

Chilled ceilings have been increasingly used in recent years to also heat rooms. Conversely, a trend has also developed towards using ceiling heating systems for cooling as well. This reduces investment costs. The operation of the systems also incurs fewer costs because only one service is required.

Because Ceiling Heating Works

Learning from Nature

No one would dispute that the heat from the sun has a very pleasant and direct effect on cool days. Ceiling heating also radiates from above with mild temperatures on the occupants below. All other objects in the room and all room enclosing surfaces are also heated by the radiant heat from the ceiling heating. Since the floor is thermally insulated, the radiant heat from the ceiling is absorbed there and the floor surface is even slightly warmer than the indoor temperature. This means there is no need to worry about cold feet with ceiling heating.

Since the surface temperature of the ceiling is not significantly higher than the temperature in the room, the thermal lift is also insignificant. The room is not heated by warm air rising but almost exclusively by radiant heat.

Advantages of Ceiling Heating and Cooling

  • Modelled on Nature
  • Directly perceived heat
  • Low energy consumption costs

Cooling Ceilings – Always a Good Choice

Cooling ceiling technology has successfully been used for many years as an energy-efficient technology for removing dry cooling loads. Cooling ceilings are optimal in thermo-physiological terms when used in conjunction with ventilation systems for conditioning the indoor air in regard to the air humidity and hygienically required air changes. They therefore create a high degree of acceptance and satisfaction with respect to the thermal comfort of the occupants. The risk of condensation on the cooled ceiling is reliably and safely prevented by limiting supply temperature and conditioning fresh air. Cooling ceilings cool without air movement that could cause draughts. This is why cooling ceilings have a positive effect on comfort. Since the perceived room temperature under cooling ceilings is slightly below or above the actual room temperature, additional positive effects are created with regard to the energy efficiency of the system.

With BEKA capillary tube mats, BEKA serpentine copper tubing or BEKA single pipe technology, it is possible to construct both radiant and convective cooling ceilings.

Ceiling Heating & Cooling for Energy-Efficient Construction

 

Energy-efficient radiant heating and low-cost construction are not a contradiction in terms. This can be seen in the model house constructed by Bau- und Ausbau GmbH in Berlin Staaken. Comfort is provided by ceiling heating and cooling in combination with a heat pump and photovoltaic system for single-family homes.
