An Advanced Economizer Controller for Dual Duct Air Handling Systems - with a Case Application
Abstract
Heating penalty is expected when economizers
are applied to dual-duct air handling systems.
The heating penalty can even be higher than the
cooling savings when the hot air flow is higher
than the cold air flow. To avoid the excessive
heating penalty, advanced economizers are
developed in this paper. The application of the
advanced economizer has resulted in $7,00O/yr
savings in one 95,000 ft2 school building since
1993. The impacts of cold and hot deck settings
on the energy consumption are also discussed.
