I have provide a load calculation for a building which is supposed to have a chiller plant to provide cooling through a fan coil unit and an AHU system to provide just fresh air(outdoor air ventilation) through diffusers. some amount of chilled water will be supplied to the AHU to have the outdoor air treated. I have been using carrier HAP and my challenge is how to go about the system properties i.e equipment type and air system type.

thanks,
