The paper discusses results of an evaluation of literature on heating, ventilating, and air-conditioning (HVAC) systems as contaminant emission sources that affect indoor air quality (IAQ). The various literature sources and methods for characterizing HVAC emission sources are reviewed. Recent studies indicate that the HVAC system itself can act as the source of indoor pollution in nonindustrial spaces. This literature review was undertaken to identify and evaluate HVAC systems as emission sources that affect IAQ. Get this from a library!

Indoor Air Quality and HVAC Systems is a practical guide for understanding the relationship between the design, installation, operation, and maintenance of HVAC systems and achieving indoor air quality (IAQ). The book describes the individual components of HVAC systems and the role each plays in maintaining good indoor air by: HVAC Systems As Emission Sources Affecting Indoor Air Quality: A Critical Review. This study evaluates literature on heating, ventilating and air conditioning (HVAC) systems as contaminant emission sources that affect indoor air quality (IAQ). The various literature sources and methods for characterizing HVAC emission sources are reviewed. HVAC Systems and Indoor Air Quality Indoor air quality problems can be produced when contaminants enter a building with the outdoor air. Rooftop or wall-mounted air intakes are sometimes located adjacent to or downwind of building exhaust outlets or other contami-nant sources. Problems can also result if debris (e.g., bird droppings) accumulates at. investigate, and resolve indoor air quality problems. SOURCES OF INDOOR AIR CONTAMINANTS Indoor air contaminants can originate within the building or be drawn in from outdoors. If contaminant sources are not controlled, IAQ problems can arise, even if the HVAC system .

HVAC Indoor Air Quality - Ozone – Ozone is produced by nature in the way of lightning strikes the roiling waves of the ocean. Photocopiers can also produce ozone in offices. Too much ozone is hazardous to our health and needs to be vented. Mold and Mildew – Mold and mildew can be found in places where water accumulates and in dark places. HVAC Systems Can Contribute to Air Quality Problems. HVAC systems can also exacerbate indoor air quality problems. The HVAC system may be contaminated (because of mold in duct lining or bacteria on coil or filters, for example), and the system may .
