Traditional Solution
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.
