If I did a room by room heat load calculation and came up with a btu number for every room, how do I use that to determine how many cfm's the room needs

 

[vargimike]

400 cfm =12000 btu

6000 btu for room 12000/6000 =2
400/2 =200cfm i think its late and my mind is slow

no, manual S says CFM = BTU / 1.1 x delta T

Find the sensible heat ratio and lookup the equipment that will provide the capacity at that ratio, and use the airflow at which the equipment is rated at for that ratio.

Just to be clear, if you need 24,000 BTU/hr and the sensible heat ratio is 70, then you lookup equipment that will provide that, then use the airflow the manufacturer states is needed for that capacity rating.

After that, you can just use simple division to find out each room's airflow need.

This is the best short answer I can give you: I suggest you pay someone who knows.

You mean to show me how?
