Laboratory Tests for the Improvement and Development of HVAC Air Filters (PPT)

摘要

Subtitle: What laboratory tests can better represent field conditions The Product Development Cycle 1.Requirements, specs 2. Select components 3. Build prototypes 4. Laboratory tests 5. Field tests 6. Product approval 7. Current air filter standards (ASHRAE 52.2, ISO 5011) are based on dry aerosol challenges 8. These do not reflect actual field conditions and have limited success to predict filter lifetime 9. Liquid aerosol challenge provides additional information on filter performance and helps to predict field performance 10. Test methods to be developed (proprietary vs. public) .
