Radiant ceiling panels - Heating and cooling effect

Zehnder radiant ceiling panels work on a fundamental natural principle that is identical to the way in which the sun produces warmth.

Direct sunlight on a cold winters day makes us feel warm and is perceived as comfortable, despite the cold ambient air. The heating effect of the sun is produced by electromagnetic waves that penetrate the air without losing energy. This energy is only converted into heat when it comes into contact with the human body.

Radiant ceiling panels - Cooling effect

The heating method is as simple as it is effective:

The radiant panels are heated by hot water and give off energy to the room. This energy is converted into heat only when it comes into contact with the human body or other objects.

What is used to heat buildings cheaply and efficiently can also be used to cool them.

Cold water flows through the cooling ceiling. Because people and objects in the room have a higher temperature, they radiate their heat to the ceiling. At the same time, warm air inside the room rises and flows along the ceiling, where it gives off its heat to the cooling ceiling. The cooled air flows back down into the room.

Operating principle

Zehnder radiant ceiling panels function on the natural principle of solar radiation.

Thus radiant ceiling panels continue to provide pleasant and comfortable warmth at ground level, even when installed at a height of 30 metres. And do so with unique energy efficiency.

Principles of Radiant Heating

The most important consideration when choosing a heating and cooling system is energy efficiency. Zehnder radiant heating and cooling systems can save more than 40% in energy compared to other systems. And all with a pleasant indoor climate.

The following visuals compare the energy levels of radiant systems and air heating systems.

With Zehnder ZBN radiant panels, you can achieve energy savings of over 40% through efficient heating and cooling of buildings compared with other methods of heating buildings.

We spend almost three quarters of our lives indoors: at home, at work, during our leisure time. The indoor climate (temperature and air quality) is itself a big influence on our general wellbeing.
