Chilled Beams

[US Iceman]

Does anyone have experience/comments on active or passive chilled beams that might be suitable for residential applications?

How do they work for dehumidification? Any problems or concerns?

Thanks...

Bear in mind that it's about 14 years since I worked with chilled beams...
(please don't tell anybody, I'm feeling old now)

As the beams didn't have condensate drains, the chilled water entering them were kept above dew point. Any dehumidification would therefore be minimal.

But, I do know that some of the modern beams works differently, with fans and everything...

Here are a few pages worth looking into.

They were used years ago in hatcheries for cooling the young chicks.

That will keep you busy for a while....;)

We have one client with a big office where chilled beams are installed (not by us)
They're very pleased with it but as The VIking said, there is in the room a dew point controller form Jumo (Germany) which controls the water temperature to the beams.
There are no fans in the ceiling, just fed by gravity.
It's an expensive system.

Here's another to take a look at.
