Pollution from ducts: What is the reason, how to measure it and how to prevent it?
conference paper
Twelve institutes, universities and companies from seven European countries are involved in the European project, AIRLESS, started up at the beginning of 1998 to develop strategies, principles and protocols to improve and control the performance of HVAC-systems and components to enable their incorporation into codes and guidelines. Knowledge of why, when and how pollution is caused in HVAC-systems remained largely undefined. Therefore, the first step in this three-year project was to define such pollution and to investigate ways to prevent it. This paper will summarise the results of a literature study and experiments carried out on the pollution sources in the supply air ducts. According to such studies, the following three major contaminants may degrade the IAQ and should be restricted: residues of lubricant oils from duct manufacture, dust accumulating during operation or debris from the construction phase, and deposited micro-organisms, particularly when toxigenic species are present and conditions are favourable for their survival and growth
