Mixed Air Temperature, POA->MAT

When using a fresh air damper to establish or identify quantities of ventilation air the Mixed Air Formula can be used. By inserting the desired percentage of Ventilation air needed, ex. 10%, then insert the measured Return Air Temp ex 70, and the Outdoor Air Temp ex 95 the Mixed Air Temperature entering the evaporator coil should be approximately 72.5 degrees. Patience is key with this calculator.
