In cooling mode, capillary mats will generally be installed in ceilings or walls.

Ceiling cooling
Chilled ceilings are the most efficient and effective cooling solution, because the thermal agent is water, the capillaries work with very low water content (0.3 litres/sqm), the efficiency of the cooling system is 4 times higher than the efficiency of air conditioning systems. Significant energy and space savings can be achieved. When making chilled ceilings, the emphasis is on simplifying the solution in terms of execution.
In general, there are two kinds of applications:
- chilled ceilings, operating on a monolithic reinforced concrete structure, i.e.
- cooled ceilings, made with the installation of capillary mats on plasterboard tiles.
In the first case, thermal insulation between the capillary mats and the surface of the reinforced concrete slab is indicated to increase the energy efficiency of cooling. In the case of the second plasterboard clad ceilings, if a reinforced concrete slab is covered with a plasterboard slab, the use of metal fixing systems for the plasterboard slabs is indicated, thus creating a gap between the lower surface of the reinforced concrete slab of the ceiling and the plasterboard slab.
This layer of air, about 3 cm thick, acts as a layer of insulation, and greatly increases the energy efficiency of the ceiling. This solution is particularly suitable for monolithic cast reinforced concrete slabs where the ceiling surface is not perfectly smooth and a thicker plaster layer would be required to achieve a flat, aesthetic surface.
In the case of chilled radiant ceilings, the use of gypsum plasterboard is indicated, so that the rough ceiling surface can be hidden behind the supporting structure of the tiles.
In these ceilings, the capillary mats will be fixed to the surface of the plasterboard and plastered with a layer of plaster about 1 cm thick. Fixing the staples to the plasterboard structure can be done quickly and efficiently using the industrial, pneumatic stapler.
Chilled ceilings can also be made where the capillary mats are fitted behind the plasterboard. In these cases, rigorous design and careful workmanship is required in terms of marking the areas where the gypsum plasterboards are to be fixed to the ceiling supports. When making chilled ceilings, it is mandatory to install dew temperature sensors!
