This guide specification covers evaporative
cooling systems. As mentioned in the ASHRAE
Handbook Applications, evaporative cooling systems
provide life cycle cost savings in many areas of the
U.S. Evaporative cooling may be used for total
cooling or for precooling of outdoor or mixed return
air. Other potential uses are also addressed in the
ASHRAE Handbook Applications. Types of evaporative
cooling equipment are described in the ASHRAE
Handbook Systems and Equipment. Use of evaporative
is further discussed in UFC 3-410-01FA Heating,
Ventilating, and Air Conditioning.
