Duct-Induced House Pressures (Micro Course) 0.7 CEUs
(0.7 CEU; 45 minutes) Building pressures cause air infiltration and exfiltration. Unbalanced airflow between supply and return ducts causes positive pressures in some rooms and negative pressures in others. Duct air leakage in intermediate zones makes the building either positively or negatively pressurized. This micro course explains these effects and how to solve the problems they create.
