I obtained 11.1 tons as the Cooling Capacity on auto-sizing. But, the
air flow rate used for that cooling capacity (obtained from the
HVACSizing for Cooling) is only 2110 cfm. In that case, am I doing
anything wrong with the model? or is it usual?
At the same time, the air flow rate (obtained from the HVACSizing for
Heating) is around 3910 cfm.
Could you please tell me what is right.
Thank you very much.

Enter the flow rate
that was used for the Rated Cooling Capacity. For
example, for a 10-ton air conditioner (the Rated Cooling Capacity), the
air flow rate would be around 4000 cfm (400 cfm/ton).
