Notes:

1. Data is rated in accordance with ARI Standard 590-92, Section 7.3.

  • 44°F leaving chilled water temperature.
  • (55°F + 0.4°F x % Load) = entering ambient temperature.
  • Constant evaporator waterflow as determined at full load operation at 95°F and 10°F evaporator temperature drop.
  • % Load by compressor displacement as defined by ARI Standard 590-92.

2. EER = Energy Efficiency Ratio, (Btu/watt-hour). Power inputs include compressors, condenser fans and control power.
