Anyone have a good site and/or formula for BTU calculation loads?
I'm researching ventilation air heating requirements and am trying to find out:
640cfm @ delta T 15 deg. F rise (100% humidity) = ?BTUs?
640cfm @ delta T 15 deg. F rise (50% humidity) = ?BTU?
It's for intake air from a geothermal source (55 dwg. F +/-) being brought to room temp (70 dwg. F +/-) with the varying humidity loads. I'm not looking for exact stuff, just theoretical schematic planning stuff...Thanks!
