Cooling
Principles known for a very long period of time are used in the case of most alternative methods of cooling. A number of designs are inspired by historical solutions in which the alternative methods of cooling have been applied. It is necessary not only to reinvent low energy consumption methods of cooling but also to use new tools and technologies in designing and dimensioning these systems fully.
Adiabatic cooling is one of the solutions using conversion of perceptible heat to latent heat while water is evaporated, as a result of which the air temperature is decreased. Direct adiabatic cooling is suitable above all for dry, hot or warm climates where a high humidity of air as well as cooling is required at the same time. The fact that adiabatic cooling units do not require any other devices to be installed in air systems is their advantage. Alternative cooling methods bring about both increased thermal comfort in buildings without air conditioning and considerable reduction of power consumption. All this corresponds to the use of the facility in accordance with its conception.

Reduction of thermal load from manufacturing technology

The thermal gains accumulating in the course of a production process cannot always be removed from the production hall through pure ventilation. Adiabatic cooling units are used in such cases. The cooling device is usually installed outside the building – e.g. on the roof, and cooled, humid air is supplied by means of a distribution head or distribution ducts to the hall. The adiabatic cooling works on the basis of a simple principle of water evapouration removing heat from the surrounding area, a comfortable environment being the result.
As compared with standard cooling systems with air-conditioning units, this is an overpressure system providing the building with ventilation, therefore the doors do not have to be closed during cooling operation. This type of cooling can be used in industrial buildings such as heavy industry, warehouse halls and in agricultural livestock buildings.

The system includes a central ventilation unit, internal adiabatic cooling/humidifying units, duct distribution systems, separate supply fans and exhaust roof fans. If cooling is required, the heat recovery unit operates in the air by-pass mode, but if the cooling requirement becomes increased, auxiliary fans with the supply ducts will be switched on. The adiabatic units are installed approximately on the level of 3 m above the floor and fresh air is supplied both directly from the outside through ducts and from the heat recovery unit during the cooling mode.
Air is exchanged 15 times an hour and the air temperature is 28°C on the level of 4 m above the floor. Warmer air rising naturally above this level will be exhausted by the heat recovery unit and roof fans. The roof fans ensure air exhaust at the total output of 24,000 m3/h.
