I feel ashamed being an ME, but I havent had to deal with energy balances and HVAC in over 20 years.
The air is being drawn from the top level of a Kiln, which is always at 100-110 deg F. The manufacturer spec'd the blower @ 1800 CFM with 1/2hp motor.
The "shack" is a sheet metal building...
Im trying to verify correct sizing of a blower system. A 12" blower w/ 1/2HP blows approx. 1800 cfm of 100 deg F air into a 6000 cu ft shack, that ranges to lows of 0 deg F ambient. How do I calculate supplied BTU's and also required BTU's to raise the temp to 45 deg F?
Thanks for the help.
