Dear All,

Please excuse my ignorance, but how would you calculate the fan power of
FCU units for modelling the proposed case? Looking at the manufacturer
specifications (McQuay), I am dividing input power by the airflow rate,
which is giving me values around 0,0002600 kw/CFM (for example 318 CFM at
80 W). However, many other energy studies that I have seen are using
values like 0,00045 kW/CFM.

Are my values normal or am I again missing something here?

I would appreciate any feedback,

Regards,
