Design Aspects of Energy-Efficient Systems

In the design of air-handling systems, a reasonable energy efficiency can be achieved by relatively simple means, just paying attention to some basic principles. 

To give the designer some advice, many recommendations exist in literature. Some general recommendations can be found in prEN 13779 for designing the air distribution system for low energy consumption. These include giving a certain target level for power consumption [the so-called SEP class. SEP means specific fan power, the ratio between the input power of fan mo tors and the total airflow, in W/(m s )]. 

Ttbles 9.20 and 9.21 present recommendations for maximum pressure drops of components in the supply and extract air systems in order to achieve a certain target level for power consumption in the whole system. In category Low, this target level is 1500 in Normal, 2500 and in High 4000 W/(mVs),
