Top Ten Strategies for Low Energy Fan Systems in
Cleanrooms
Peter Rumsey, PE, Rumsey Engineers,
Inc. Typical energy savings on fan systems vary widely. Nevertheless,
thoughtfully designs have resulted in fan energy savings in the
30% to 70% range have been achieved. These savings are shown in
the energy performance of bench marked systems where the difference
from best to worst was a factor of five to one.
This presentation will pull together experience from looking at
energy use in over 50 cleanroom facilities in three continents.
Mr. Rumsey will summarize the top ten energy savings opportunities
in fan energy systems in cleanrooms. After process loads and chilled
water loads, fan energy is typically the third largest energy use
in cleanrooms. Benchmarking data collected by Lawrence Berkeley
National Laboratory indicate that fans typically account for 5%
to 20% of all energy use in cleanrooms. Mr. Rumsey will pull the
top ten concepts together in a case study example that shows the
cumulative impact of these ideas. Labs21 Connection:
Cleanrooms are now part of many laboratory and biotech facilities.
Fan systems in cleanrooms are unique and different from laboratories.
Years of experience in these systems from the microelectronics industry
needs to be shared and adopted as fast as possible in order to not
miss the opportunity to design these facilities right from the get
go.
Biography:
Peter Rumsey, PE, is the founder and principal of Rumsey
Engineers, Inc. Rumsey Engineers has pioneered low energy cleanrooms
for many years. Peter has designed and consulted on a wide variety
of cleanroom facilities. He has worked with Lawrence Berkeley National
Laboratory on their cleanroom benchmarking project. In 2002 he was
awarded a regional award from ASHRAE for a low energy cleanroom
design in Phoenix, Arizona.
Peter is a member of the ASHRAE cleanrooms committee (TC 9.11) and
is a registered engineer in over ten states.
