[Equest-users] Fan Motor Efficiency Change

[Jeremy McClanathan]

I account for motor eff by changing the total eff, where total eff = motor eff * mech eff.  I believe the keyword for total eff in the inp file is SUPPLY-EFF for supply fans.

Thank you, Demba.

But this is for a PUMP. Not a FAN.

John,

In the INP, it is the “MOTOR-CLASS” input. You see in the INP something like:

FLOW             = 300
                NUMBER           = 1
                HEAD             = 80
                MECH-EFF         = 0.776
                MOTOR-CLASS      = HI-EFF
                CAP-CTRL         = ONE-SPEED-PUMP

I should know this one, but draw a blank.

The Wizard asks if you want Standard, Hi Efficiency, or Premium Efficiency motors for your fan system.

How do those show up in the .INP file? That will give me a clue as to what Parameters to modify for changing to PE motors.

Thanks.
