Floor Radiant Cooling System

Under optimal design conditions capacities of a floor system up to 16 btu h ft can be achieved with more typical capacities in the 8 to 12 btu h ft range.

Similarly water can accumulate on flooring cooled by a radiant floor cooling system. Radiant cooling systems typically use chilled water running in pipes in thermal contact with the surface. 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. But mackay writes that he is building in climate zone 6a where humidity ranges between 20 and 35.

Radiant cooling from a slab can be delivered to a space from the floor or ceiling. Chilled water between 55f to 58f is circulated through the pipes which are embedded in either floor or ceiling. Radiant cooling slabs use similar design and sizing principles as a hydronic radiant floor system using the same types of pex pipes manifolds and pumps as in heating. Since radiant heating systems tend to be in the floor the obvious choice would be to use the same circulation system for cooled water.

Types of radiant cooling systems. The capacity of a radiant cooling system depends on factors such as insulation pipe spacing floor construction and indoor air temperatures. While this makes sense in some cases delivering cooling from the ceiling has several advantages.
