Dear All,

I would like to model my fan coil units with static pressure and total
efficiency inputs. While the static pressure is clear, I do not know how
to calculate the total efficiency as the manufacturer specifications do
not have it.

Is there a way to estimate the efficiency when the following are known
(this is a typical McQuay fan coil unit):

- Forward curved centrifugal type fans
- Permanent split capacitor motors (115/60/1).

Thank you,

Omer Moltay
