Mobile air cooling and ventilation systems bring fresh, cooled, purified and dehumidified air into the space, which collapses by gravity to the floor and thus floods the occupants, and displaces polluted and hot air to higher layers and outdoors through openings.
System operation
Our solutions are based on the installation of packaged chillers with different cooling capacities, ranging from 17 to 48.2 kW of cooling power.
These units supply up to 8,200m3/h of fresh, dehumidified and cooled air to the room through perforated PVC ducts of Ø500 mm profile or suitable textile ducts.
The units are placed on the ground or on the roof next to the building and are connected to the electricity supply in accordance with the regulations.
They may be switched on and off outside (on individual units) or inside.
A flexible hose shall be routed through the wall from the individual unit to the blowing line.
The inlet duct shall be laid in a straight line at a height of approx.
3 to 4 m below the level of the luminaires.
The cooling device shall normally take 100% outside fresh air.
It filters the air, cools it by about 13°C and dehumidifies it.
The treated fresh air is ducted into the space by gravity and collapses towards the ground.
In this respect, people and appliances within the treated fresh air zone are heat generators, which, by heating the air on their surfaces, cause thermal buoyancy of the heated air, which in turn forms a heat column above each heat source, which penetrates through the cold air layer and accumulates under the ceiling.
The uplift of air at the heat sources implies the absorption of cold air at the floor.
This creates a continuous process of heat dissipation and vapour emission to higher air layers and outdoors.
This gives a very stable room condition with a slight overpressure, no draughts and a large temperature difference in height, with the work surfaces in a stable zone of fresh and thermally treated air.
Hence the energy efficiency of the operation of cooling systems, since by displacing the upper air layers to the open air, we achieve the so-called heat displacement effect, which means that only a small part of the heat is overcome directly by cooling, while a very large part of the heat and harmful vapours are displaced to the open air by the fresh supply air.
