Calculate mixed air conditions from two air streams. Determine the mixed temperature, humidity ratio, and enthalpy for HVAC systems.
Mixed air is the combination of return air from the building and outside fresh air, mixed in the air handling unit before being conditioned.
It is calculated using the mass flow rates and temperatures of the two individual air streams. Our calculator performs this mass balance equation automatically.
Knowing the mixed air conditions is essential to determine the actual cooling or heating load the HVAC coil must handle.
Yes, by calculating the mixed air temperature and enthalpy under various outside air fractions, you can determine the optimal economizer setpoints and maximize free cooling efficiency in your building.
