A new approach to air handling
January 1st 2008 As part of its Energy-Saver
programme, Eaton-Williams has a
new approach to air handling
design in the form of its fan wall
technology. Air handlers using the
technology are said to be 6-10%
more energy efficient.
Fan wall technology solves
many of the problems
usually associated
with the
upgrade of air
handlers,
particularly in
older
structures. At
the same time it
can increase
efficiency and control
temperature and humidity
levels. It is suitable for both
refurbishment projects, new build
or any project requiring a solution
where there are stringent size,
reliability and noise criteria.
The design features the LKP fan
wall array that can be adjusted by
turning one or more fans off,
enabling remaining fans and
motors to be fully loaded at or near
peak efficiency.
Variable speed drives permit
adjustment of airflow rates by
turning fans on or off and smaller
fans reduce low frequency noise
generation. Additional noise
reduction is achieved by
surrounding each fan on all four
sides in the array with sound
absorbing enclosures. The
use of direct drive
fan drives
eliminates drive
losses and
improves
mechanical
efficiency by as
much as five
percent.
Additional efficiency
improvements include an
improved aerodynamic
performance with the elimination of
belt guards, large fan pedestals
and much of the structure
traditionally found in air handlers to
support motors and belt drive
mechanisms. More articles from Eaton-Williams Group Ltd: |
