Zehnder heating and cooling ceiling system: Functional principle heating - Video

The same method of heating 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 also rises and gives off its heat to the cooling ceiling. The cooled air flows back down into the room.
