In this article, we will provide an in-depth look at ESP calculation in HVAC, its importance, and a step-by-step guide on how to perform ESP calculations using an Excel sheet. It is typically measured in inches of water
ESP = 0.5 + 1.2 + 2.5 + 0.8 = $ \(5\) $ iwg
External Static Pressure (ESP) is the total pressure drop across a HVAC system, including the supply and return ductwork, filters, coils, and other components. It is typically measured in inches of water gauge (iwg) or Pascals (Pa). ESP is an essential parameter in HVAC system design, as it affects the system’s airflow, energy consumption, and overall performance.
