An optimal working environment raises the productivity of people. Chilled ceilings by Armstrong help in the attainment of this objective:

Chilled ceilings - a new air-conditioning concept
Most conventional chilled ceilings operate via the forced air principle. Warm air is re-circulated and replaced by recycled and cooled air. This exchange results in a draught of cool air. An additional problem with this system is what is known as the "sick building syndrome". Non-maintained air ducts of an air-conditioning system can blow bacterial pathogens into a room thereby contaminating the air. This can lead to the rapid spread of diseases.

Chilled ceilings based on radiant cooling technology allow for an entirely new way of air treatment - a method that solves both problems. The ceiling panels of radiant cooling systems contain chilled water which flows through tubing mounted on the rear of the ceiling panels. The ceiling panels function as heat exchangers between the room air and chilled water. The ceiling absorbs heat generated by the heat sources in a room and exchanges it with the circulating chilled water.


Operating principle of a chilled ceiling
From a technical viewpoint, a radiant cooling ceiling is simply a large heat exchanger that is suspended from a room's ceiling. It exchanges energy via the room's radiation and convection.
