In Floor Radiant Heating And Cooling
No hot or cold spot and no wind noise or draft occurs when cooling with radiant floor heating.
In floor radiant heating and cooling. A typical circulation pump consumes only 5 amps when cooling or heating a house. Radiant cooling can be use in conjunction with radiant heating systems utilizing the same network of raupex pipe embedded in a surface. A typical fan coil ac unit can run as high 8 10 amps just to run the fan motor. Radiant cooling from a slab can be delivered to a space from the floor or ceiling.
The complexity of the system adds to the cost and air conditioning must be added separately. In a hydronic radiant floor heating system plastic tubing distributes hot water around the house from a central manifold like this one. Radiant cooling systems have been embedded in the ceilings of adobe homes taking advantage of the thermal mass to provide a steady cooling effect. While this makes sense in some cases delivering cooling from the ceiling has several advantages.
Since radiant heating systems tend to be in the floor the obvious choice would be to use the same circulation system for cooled water. 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. 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.
For the ultimate in efficiency couple radiant cooling with geoexchange systems.
