3.3.3 Pressure drops of hot water coil hydraulic circuit
3.3.2 Hot water coil correction factors (HOWA)
The hot water coil capacity in different conditions can be obtained multiplying the nominal capacity (See above), by the correction factor
indicated in the table.
The graphic below shows the pressure drops of the hydraulic circuit that includes the hot water coil and the 3 way modulating valve.
