Free Cooling AHU

Taking advantage of favourable outside conditions

Free cooling is a highly efficient method that uses low temperature outdoor air to control the data centre considerably, thus reducing total energy consumption. Considering ASHRAE regulations for IT equipment and optimum
operating conditions, it is possible to free cool all the time or for some time of the year in most countries.

Systemair’s free cooling technology results in class-leading efficiency.

Just one example of saving: Calculations based on a one year power saving of approximately 180,000 kW in Madrid, show that it is possible to estimate, for a five year basis and unit power of 250 kW, an average energy saving of 3,600,000 kWh.

In terms of money, cost reduction would add up to a total of more than 432,000€ during the same period
of time, using an energy cost reference value of 0.12 €/kWh.
