Abstract
This paper first investigates the fan energy
performance of a constant air volume exhaust system.
Two single stack energy efficient exhaust fan systems
(E3S3F) are presented. The E3S3F-I has the static
pressure sensor located at the inlet of the exhaust
fan. It has been found to consume up to 15% less fan
power than conventional constant air volume exhaust
systems. The E3S3F-II uses a variable speed device to
maintain the static pressure at the entrance of the
stack. It consumes up to 60% less fan power than
conventional constant volume exhaust systems.
