In traditional constant air volume
systems, air is conducted across cooling and heating coils and into
the building ductwork. A return fan may also be a part of the CAV
system. The return fan extracts air from the conditioned zone back
to the air handling unit (AHU) where it is either recirculated or
exhausted outside. A temperature sensor in the return duct supplies
signals to a controller for the heating and cooling coil valves. The
valve controller regulates water flow to the coil to maintain the
correct temperature in the conditioned space.
