How to calculate AHU capacity from CFM

lovey01384 · June 2, 2017, 10:59am

Dear Ankur Ji,

I have an AHU with 1300 CFM. With this AHU i have to supply air in change rooms, core areas. How I can calculate that thuis AHU is capable of taking that much load or not.

Please suggest !!!

Simply sum the required CFM (according to cleanliness class) of all rooms/areas.
