But the full engineering formula is:

TESP (Total External Static Pressure) includes everything outside the fan housing. In practice, ESP = TESP. esp calculation hvac excel sheet

For engineers, technicians, and contractors, calculating ESP manually can be tedious and error-prone. That’s where an becomes indispensable. But the full engineering formula is: TESP (Total

ESP is the measure of resistance that the fan must overcome to move air through the supply and return ducts, grilles, filters, coils, and other external components. Simply put: Too much resistance, and the system suffocates. Too little, and the motor over-speeds. ESP = TESP. For engineers
