Operating Cost/Efficiency - Trane Fan User Manual

Operating Cost/Efficiency

The quiet Q fan is a very efficient fan.
The Q fan mixed-flow type airfoil thrust
blades offer outstanding efficiency and
operating cost savings over such fan
types as plug fans. Designers can
compare the Q fan efficiency with other
fans by using the fan selection program
and the Trane Customer Direct Service
(C.D.S. ™ ) Network FanMod program.

The Trane fan selection program
provides accurate part load energy
consumption no matter what fan
modulation method is selected. The
FanMod program compares two or
more fans economically for one or
more years. FanMod is an easy-to-use
program for equipment life cycle cost
analysis.

When comparing the Q fan
performance with centrifugal fans,
remember to recalculate the fan
external static pressure. The in-line
delivery of the Q fan often eliminates
the need for a 90 degree turn right off
the fan outlet. Turns directly
downstream of the fan outlet consume
energy and generate noise and,
therefore, should be avoided whenever
possible.
