What would the mixed air temperature be for a system with 20% outdoor air if the outdoor temperature is 90°F and the return air temperature is 80°F?
A) 0.2 × 90°F = 18°F; 0.8 × 80°F = 64°F; 18°F + 64°F = 82°F mixed air temperature B) (90°F + 80°F) ? .4 = 68°F C) 0.8 × 90°F = 18°F; 18°F + 80°F = 98°F mixed air temperature D) ( 90°F + 80°F ) / 2 = 85°F mixed air temperature
