    Notes:
  1. N/A - Condensing unit is not available.
  2. All Units use refrigerant R-404A and their selections are based on a capacity match of ±10% relative to the XJ Outdoor Unit.
  3. Hermetic Reciprocating, Standard Scroll and Semi-Hermetic refer to condensing units using these compressor technologies.
  4. Refrigeration Load is assumed to be constant in the analysis. It assumes that Walk-In Cooler/Freezer is located indoors and the surrounding ambient is at constant 90°F temperature.
  5. Design Refrigeration Load for analysis is based on Outdoor Unit's (XJ) Capacity at 90°F ambient air and 25°F evaporator temperature condition.
  6. Unit Performance is based at 40°F to 65°F Return Gas temperature, 5F Subcooling for all units except for XJ Low Temperature units which have higher Subcooling. We use Actual Subcooling for these units. Minimum Condensing Temperature is set at 70°F for estimation of Annual Operating Cost.
  7. Operating cost for Evaporator Fan or Power required for the Defrost Cycle are not included in the annual operating cost or saving analysis.
  8. Weather data is based on typical metrological year obtained from National Solar Radiation Database, Years: 1961 - 1990. Analysis use weather data of:
    Minneapolis, MN (Zone 1), Dayton, OH (Zone 2), St. Louis, MO (Zone 3), Atlanta, GA (Zone 4), Miami, FL (Zone 5).
  9. Sample annual energy analysis describing the procedure may be viewed by choosing AEER.
  10. Additional information on AEER methodology and calculation is available in Emerson's AEER White Paper or by viewing the AEER Webinar.

Energy savings estimates based on rated equipment performance and assumptions are noted. Actual savings dependent on box load sizing calculations and system component matching, and may vary by type of application and other operational variables not considered.
