Energy conservation strategies and production
economies involve more than examining the
cooling tower fan consumption of horse power.
Colder water provides vast potentials for
savings. Ask yourself, "What is the dollar
and energy utilization value if I can obtain 1°F
colder water off my cooling tower than I am
now getting?" Therefore, let us first examine
the elements of the cooling tower to determine
the areas of greatest potential improvement to
generate that colder water.
The air flow generated by the fan should first
be looked at In both counterflow or crossflow
towers to determine that maximum flow is
available through pitching fans up to within
the motor plate amperage limitations and fan
stall point calculations. If applicable, new
fiberglass state of the art fans can be installed
and additional motor horse power added.
However, the most dramatic improvement that
can be obtained in producing colder water is
to retrofit modern film fill to replace the old
fashioned wood splash bar slats
