A central station air handling unit is an enclosed
cabinet which houses a fan and/or cooling and heating coils, filters
and other accessories. These units provide either ventilation,
cooling and/or heating, humidification, de-humidification and
filtration for the air. The term "central station"
refers to the location of these units which are generally in a
central mechanical room in the building. Supply and return air
ductwork is attached to these units to provide conditioned air
to the building. Central station air handlers are usually customized
for the particular application. A wide variety of fan wheel types
are available including forward-curved, airfoil and backward-inclined
for meeting static pressure and airflow requirements. With nearly
an infinite possibility of combinations of accessories, components
and arrangements, central station air handlers are widely applied
in applications requiring close tolerances of control of building
temperature, relative humidity and air quality.
