Variable Speed Drive (VSD) Applications in Dual-Duct Constant Volume Systems
Abstract
Models have been developed for static pressure
and potential supply fan energy savings by using
variable speed drive (VSD) in dual-duct constant
volume systems. Experiments have been performed
using a full size dual-duct constant volume system
installed in a 68,000 ft2 (6,317 m2) office and
classroom building. The measured static pressure
variations and the energy savings agree with the
model projected values. The VSD saves the fan
power by as much as 35%, reduces the total airflow
by 15%, and decreases the excessive static pressure
on the terminal box dampers. This paper presents
the systems models, the experimental methods and
the results.
