Abstract
In an effort to improve building energy and indoor air quality models, relations to describe the airflow characteristics of back-draft dampers were determined. In particular, two equations were developed to represent the relationship between pressure drop and airflow rate for one-blade and multi-blade back-draft dampers. The equation for multi-blade dampers was validated by comparing the predicted results with available Air Movement and Control Association (AMCA) 500-D test data. The results showed that these two equations can be used to model the airflow characteristics of back-draft dampers.
