radiant cooling

Gary Usa_2

may I ask the following question please,as i am trying learn all about radiant heating is heir a concept about using radiant to cool the floors.but as i was thinking if it was cooled would it then create a problem of condensation and humidity within the floor,how could you set up a cooling radiant system,would it be affective etc,as we know wouldn;t want to cool the floor to much other wise it will become too cold to walk on,etc,and maybe cause more problems than just a cool floor,when pex is installed in a wall wouldn;t that be a better way so that the walls are used for cooling in the summer and the floor used for heating,well i better stop rambling otherwaise i may ask another silly question,lololo

happy holidays

all the best

Cooling in a building

is about dehumidification most of the time. I personally know two companies that have tried to work with it. Heatway put in a wall and let the moisture condense and drain off of it. It made the room cool and humid. Barber-Coleman (now Invensys) did a bunch of studies in the mid 90's on ceiling and control systems and how to get a benefit and payback. I believe it was abandoned. On the plus side I have seen articles on reverse floor heating to "unload" the heat in commercial office buildings in hot dry climates. Here you would like to keep some humidity and yet be cool and this would help with only the BTU rejection. There was also a company (Europe ??) that had a system that hung down from the ceiling like a long gutter with fintube and the cool air would drop down and cause convective curents like the heat from baseboard rises. Ummm...yes, someone has been thinking about it.

radiant cooling works gary

at least in northern mass. using 56 degree well water i cool my floors to 68 degrees with my existing staple up radiant heating system. 68 degrees is above the dew point so i get no condensation. i also have a fan-coil unit with a drip pan underneath that helps remove condensation and provide air circulation. i have heard that radiant cooled ceilings work better but walking barefoot on a cool floor really cools you off fast, and the radiant heating pipes are already in place. my house stays around 70 dagrees.
