In Floor Radiant Heating And Cooling

For the ultimate in efficiency couple radiant cooling with geoexchange systems.

In floor radiant heating and cooling.

Radiant floor cooling radiantec has promoted open direct radiant floor heating that also has a limited cooling capacity. A typical fan coil ac unit can run as high 8 10 amps just to run the fan motor. Since radiant heating systems tend to be in the floor the obvious choice would be to use the same circulation system for cooled water. Radiant cooling systems have been embedded in the ceilings of adobe homes taking advantage of the thermal mass to provide a steady cooling effect.

In a hydronic radiant floor heating system plastic tubing distributes hot water around the house from a central manifold like this one. No hot or cold spot and no wind noise or draft occurs when cooling with radiant floor heating. A typical circulation pump consumes only 5 amps when cooling or heating a house. Incoming cold water from the homes well is directed through the radiant tubing prior to reaching the tap.

Radiant cooling from a slab can be delivered to a space from the floor or ceiling. Another advantage is the even distribution of cooling heating in the home. Radiant cooling is an energy efficient way to address sensible loads in a space. The complexity of the system adds to the cost and air conditioning must be added separately.

Homes built on concrete slabs are prime candidates for radiant heating systems and radiant floor cooling takes advantage of the same principle using chilled water.
