Abstract:
A method of controlling the mixing of outside air and return air, entering an air handling unit, through inlets having dampers, the air handling unit having a coil for conditioning the incoming air and a fan for blowing the conditioned air into a conditioned space, the method including measuring the outside air temperature, and return air temperature, and a minimum coil temperature corresponding to a damper position calculating a correlation values from the outside air, return air, and a minimum temperatures determining a correlation function from the correlation value and damper positions, and using the correlation function to calculate the maximum damper position for an acceptable coil temperature.
