Abstract:
1. A method for controlling a conditioning space including a plurality of zones via a plurality of zone environmental units comprising: receiving a plurality of temperature values and a plurality of airflow values, the plurality of temperature values and the plurality of airflow values associated with the plurality of zones; determining a minimum number of operating supply fans based upon the plurality of airflow values; operating a first group of supply fans comprising the minimum number of supply fans, each one of the first group of supply fans having a characteristic time offset difference greater than a minimum time offset difference and a characteristic temperature difference greater than a minimum temperature difference; and operating a second group of supply fans, each one of the second group of supply fans having at least one of (A) a characteristic temperature difference greater than a maximum temperature difference or (B) a characteristic time offset difference greater than a maximum time offset difference and a characteristic temperature difference greater than a minimum temperature difference.
