  1. NOTES
    1. Rated (60Hz unit) in accordance with AHRI Standard 550/590 at standard rating conditions.
    2. Standard rating conditions are as follows:

    Cooler Conditions:
    Leaving Water Temperature: 44°F (6.7°C)
    Flow: 2.4gpm per ton (0.043 L/s per kW)

    Condenser Conditions:
    Entering Water Temperature: 85°F (29.4°C)
    Flow: 3.0gpm per ton (0.054 L/s per kW)

    Fouling Factor (Cooler):
    0.00010 hr x sq ft x °F per Btuh (0.000018m2 x K per W)

    Fouling Factor (Condenser):
    0.00025 hr x sq ft x °F per Btuh (0.000044m2 x K per W)
  •  IPLV is a single number part load efficiency value calculated from using the efficiency values at 100%, 75%, 50%, and 25% of load when the chiller is operating in AHRI conditions
