The Air Handling units generally consisting Cooling coils (water cooled of DX type) and Heating (Electric or steam ) are followed by air filters. The design of air flow calculation is done considering pressure drop filters are about 75 % chock .In actual use when filters are new or replaced the pressure drop is very less and we get high airflow which subsequently increases the Cooling and heating Load on system .If we put a velocity sensor after the filters which input fed PLC (Programmable Logical Controller) ,the motor RPM can be controlled ,saving the excess westage of Energy and pollution
