I want to reuse a 36" main duct originally sized for 14 000 cfm but now with only 7000 cfm. Do the VAVs remaining in the system supplied by this main duct will be able to operate properly?
Regarding the cold deck supplying this system. Can I resize the coils and the fan for 7000 cfm (originally sized at 14 000 cfm). Is this cause any problem?
