Functions

public pure function GetOnOffFan(Mode, MotEff, FanPower, MotInAirFrac, InletAirEnthalpy, AirMassFlowRate) result(OutletAirEnthalpy)

Simplified version of SimOnOffFan subroutine in EnergyPlus Given the mode of operation (on or off), fan motor efficiency, power of the fan, fraction of motor heat entering air stream moist air enthaply of the air entering the fan, and mass flow rate, it returns the moist air enthaply of the air after it has passed through the fan. It assumes sensible heating process only - i.e. it does not change the moisture in the air - and the mass flow rate across the component remains the same.
