Mixed Air Description

This mixed air calculator can be a very handy tool for an HVAC engineer when they want to do a quick mixed air calculation but don't have a calculator nearby, or in my case, too lazy ;) Just input your known outdoor air and return air conditions (both cfm and temperature) and hit calculate to see the results. The schematic on the right is not interactive, however the 1, 2, and 3 indicators in the table correlate to the numbers on the schematic to give you a visual of what exactly you're inputing into the calculator.
