What Are Acoustic Chilled Ceiling Panels and How Do They Work?

During the grand opening of the REHAU MONTANA ecosmart house, the public got a look at the first installation in North America of REHAU’s acoustic chilled ceiling panels. Naturally, there were a lot of questions about this new technology.


How energy efficient is a chilled ceiling panel system? How does it work? How is it installed? What kind of climate is it best suited for?



Ceiling Panels Absorb Radiant Energy, Air Requirements are Reduced

The system uses radiant technology. The ceiling panels absorb radiant energy from warmer room surfaces and people. Part of the overall cooling mechanism is the convective cooling of warmer stratified air at the ceiling. Water circulating through the radiant panels carries off the sensible heat absorbed by the panels.



Air requirements are reduced because radiant panels are doing the majority of the sensible cooling. The required ventilation air-based system picks up the latent cooling load and maintains the design dew point. The remaining portion of the sensible cooling is done by the ventilation air.



Best Balance Between the Human Body and its Surroundings


Radiant cooling and heating provide one of the best balances between the human body and its surroundings. In winter, the radiant ceiling transfers heat to the outer walls, furniture, and floors which reduce heat loss from the occupants to these surfaces. In summer, a cooled radiant ceiling absorbs sensible heat from these same surfaces and the human body dissipates heat to the cooler radiant ceiling. Typical forced air convective systems require large quantities of heated or cooled air which may not be as comfortable.
