ESP-External Static Pressure Calculation for HVAC Duct l ASHRAE Standard l Step By Step Procedures

External Static Pressure is the calculation of all the resistance in the supply & return duct system (Duct fittings, Dampers, Air outlets, Louvers, Sound Attenuator, etc.) that the fan has to overcome. The higher the ESP, the lower the Air Flow. The lower the ESP, the higher the Airflow. High ESP readings indicate that there is excessive resistance in the system. In order to do the ESP, First, we determine the critical path of duct along which there is the highest pressure loss. Bear in mind that this path does not necessarily be a path with the longest route, but the loss largely subject to the airflow, Q (CFM) within the path of duct and fittings. What happens when static pressure is high? • When the static pressure is high, it means that airflow is restricted. • Hot pockets may be created due to reduced flow. • With reduced / restricted air flow the same HVAC unit needs to run longer time to achieve the set point temperature. • Chances are there you may never achieve set point temperature, if air flow is reduced too much.
