Adiabatic Discharge and Exhaust Air Cooling

Adiabatic exhaust air cooling uses rainwater for cooling buildings. The water is sprayed into the exhaust air current and cools it down. A heat exchanger then cools the warm supply air with the cold exhaust air. No exchange takes place between the two air currents. Heat recovery is all that is required to use the exhaust air cooling system.

Areas of Application

There is practically no limit to the number and types of application it can be used for. Adiabatic exhaust air cooling systems are proven and tested in industry, in the commercial sector and in public facilities.

Adiabatic cooling systems consume in general less energy. Switching to adiabatic cooling saves even more electricity compared to conventional cooling systems.

The very high degree of efficiency which WinCool achieves with our adiabatic discharge and exhaust air cooling systems is the result of decades of research and development.

Hygienic cooling without the need for desludging. No risk of contamination because no circulated spray is generated.

Adiabatic high-pressure cooling can achieve a saturation of 100 % RH, which causes even more heat to be conducted away.

WinCool systems are certified in accordance with the European hygiene norm DIN EN 13779, the German norms VDI 6022, 3808 and DIN 1946 and the Austrian ÖNORM H6021 as well as the Swiss SWKI 104-01 and SWKI 99-3.

The Benefits

The principle of adiabatic discharge and exhaust air cooling is economical and preserves resources. Significant savings can be made even at high temperatures when compared to conventional systems. The level of efficiency is so high that savings in electricity or teleheating can be made in the region of up to 30 or even 50 %.

The fact that rainwater has a low salt and limescale content means that it has an added benefit compared to drinking water in that it does not need to be desalinated. This effectively halves the amount of water that is required.

WinCool provides a system which thanks to its innovative technology makes best use of all the benefits of adiabatic exhaust air cooling. For example, a saturation of over 100 % RH can be achieved during high pressure cooling. Decades spent on research and developing the systems ensure that the energy and running costs are also low. Because the water in the exhaust air current is also a potential source of germs, our cooling systems fulfil strict hygiene norms and quality requirements.
