HVAC systems as emission sources affecting indoor air quality: A critical review. Final report, September 1993-June 1994
Technical Report
·
OSTI ID:35162
The study evaluates heating, ventilating and air conditioning (HVAC) systems as contaminant emission sources that affect indoor air quality (IAQ). Various literature sources and methods for characterizing HVAC emission sources are reviewed. Available methods include in situ tests, longitudinal and cross-sectional studies, and laboratory studies. Based on the available literature, several HVAC components are cited fairly frequently as emission sources, and there is broad agreement regarding their significance. IAQ problems appear to be exacerbated by dust accumulation and by the presence of fibrous insulation. Other problems include entrainment, migration, and infiltration of indoor and outdoor contaminants that are distributed to indoor spaces by the HVAC system.
