  1. Phoenix AZ
    • ASHRAE published Summer Design Conditions of .4% for evaporative applications – Commercial and Industrial Building cold supply air temperatures provided to the entire space to be cooled can be maintained at a set point temperature of 73.39 °F (includes sensible and adiabatic cooled air exiting the MU AHU) plus adjustment for space heat gain. No compressors and refrigerants are used in the system. Significant additional energy can be saved by maintaining a cold supply air set point temperature of 74°F in the Commercial and Industrial Building.
    • Based on the Monthly Mean Dry Bulb and Wet Bulb Temperatures – Commercial and Industrial Building cold supply air temperatures provided to the entire space to be cooled can be maintained at a set point temperature of 70.27 °F (includes sensible cooled air only exiting the MU AHU) in the hottest month of August plus adjustment for space heat gain. No compressors and refrigerants are used in the system. Significant additional energy can be saved by maintaining a cold supply air set point temperature of 74 °F in the Commercial and Industrial Building.
    • The additional 4 °F to 10 °F set point temperature reduction is obtained by adding an adiabatic cooling section to the Make Up Air Handling Unit (MU AHU).
  2. San Jose CA

No compressors and refrigerants are used in the system. Significant additional energy can be saved by maintaining a cold supply air set point temperature of 74 °F in the Commercial and Industrial Building.
    • Based on the Monthly Mean Dry Bulb and Wet Bulb Temperatures – Commercial and Industrial Building cold supply air temperatures provided to the entire space to be cooled can be maintained at a set point temperature of 68.03 °F (includes sensible cooled air only exiting the MU AHU) in the hottest month of July plus adjustment for space heat gain. No compressors and refrigerants are used in the system. Significant additional energy can be saved by maintaining a cold supply air set point temperature of 74 °F in the Commercial and Industrial Building.

No compressors and refrigerants are used in the system. For approximately X hours a year, the system would operate about 5.65 °F above a set point temperature of 74 °F. The balance of the year or approximately Y hours per year is well under the 74 °F threshold.
