Particulate air filters for general ventilation - Part 2: Method of calculation for the energy performance of air cleaning devices and for the classification of the energy performance prEN ISO 12249-2

Scope

The proposed standard aims to provide a standardized method for the calculation of the energy consumption of air filters for general ventilation and a classification system to enable the user to compare various filtration devices based on their energy efficiency (i.e. the energy consumed by air filters having approximately the same air cleaning efficiency). The standard will prescribe the formulae to calculate the energy consumption for air filters for HVAC applications. The energy classification will be in classes A through G based on a tabulated criterion of allowable increase in pressure drop depending on synthetic dust load. Marking will include the energy consumption class, the filter efficiency class, and the energy consumption (kWh) on an annual basis. Cleanroom (HEPA/ULPA), nuclear and military applications are specifically excluded from this document.
