HVAC air filter system design tools: what is available and how to use them

HVAC system designers today have available computer programs which allow accurate determination of heating and cooling loads for specific building locations. In addition, there are programs which enable optimum choices for many system components (cooling coils, blowers, ductwork, etc.). There are, however, no generally accepted programs with which to determine the particulate matter indoor concentration and the air quality which will be obtained from given filter designs at specified locations. This is partially due to the complex nature of airborne particulate contamination and filtration processes, which have hindered the development of designer tools for filter systems. Air filters are often chosen on the basis of what worked somewhere. However, the design of HVAC air filter systems for particulate matter control is not entirely unquantifiable. Data are available on the nature and concentration of air contaminants in many locations world-wide, and on acceptable levels to be maintained indoors. Internationally accepted filter test standards exist which allow approximate calculation of the effect of filters on contaminant levels, and, in some cases, the expected energy consumption and cost impacts of filter systems. The proposed lecture is intended to illustrate what tools are now available to quantify the particulate matter and the design of filtration systems. Examples of performance calculations using existing data sources will be presented.
