Floor Radiant Cooling System

While this makes sense in some cases delivering cooling from the ceiling has several advantages.

Floor radiant 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. 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.

The capacity of a radiant cooling system depends on factors such as insulation pipe spacing floor construction and indoor air temperatures. The house will be well insulated and well sealed walls insulated to r 30 the roof insulated to r 60 and airtightness at 1 5 ach50. Radiant cooling from a slab can be delivered to a space from the floor or ceiling. Types of radiant cooling systems.

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. The circulating water only needs to be 2 4 c below the desired indoor air temperature heat is removed by the water flowing in the hydronic circuit once the heat from different sources in the space is absorbed by the actively cooled surface ceiling. Similarly water can accumulate on flooring cooled by a radiant floor cooling system.
