Question about CFM/Ton

1 post / 0 new


I have a question regarding the cfm/ton for one of my AHU's calculations. I have an AHU that has the following specifications calculated from HAP: 19.4 Tons, 1176 FA and 5817 supply CFM. As you can see, this gives me around ~300 cfm/ton which is lower than the minimum 350-400 cfm/ton rule of thumb. The HAP input of the AHU is 100% accurate as I revised it many times.

My question: Should I manually increase the supply CFM to meet the minimum 350 cfm/ton in my hap calculations or what?

Thanks in advance.
