Energy Efficient Single Stack Exhaust Fan Systems (E3S3F)
MetadataShow full item record
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.
