Air changes
Air changes
(OP)
Greetings,
I have been asked recently to determine the exhaust and return air changes for several areas in my hospital. Would the formula for determining these changes be the same as for determining supply air changes (Air changes per hour = CFM*60/Volume where cfm is the air flow rate (cubic feet per minute)and the volume is the volume (cubic feet) of the room)?
Thanks

RE: Air changes
(cu.ft.*60/hr)/(cu.ft./a.c.)equivalent to a.c./hr
