Manufacturing facilities
Process environments dominate the manufacturing area of HVAC ap-
plications. Typical requirements include very close control of temper-
ature (plus or minus 1
⬚
F or less is not unusual) and humidity (plus or
minus 3 to 5 percent RH is typical). These criteria can be met only by
the use of carefully designed HVAC systems and very high-quality
control devices. Clean rooms often require high airflow rates but have
normal or low heating and cooling loads. One design solution is to use
a small system to provide heating and cooling with supplemental fans
and filters to provide the necessary airflow. Research laboratory facil-
ities are also part of the manufacturing complex. Electroplating op-
