The project aimed to conduct research on the reasons for pollution caused by HVAC systems. It was found that the reasons vary widely depending on the type of construction, use and maintenance of the system. Filter and ducts are major sources of pollutants, with humidifiers and rotating heat exchangers coming a close second. Heating and cooling coils are less of a problem, as is the effect of air flow. Puts forward a new maintenance guideline based on the existing VDI 6022. Also defines strategies to decrease the pollution caused by a total HVAC system and to lower the energy consumption.
