NOTES
1. Rated 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)
3. 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.
4. All data in the above table was generated in Packaged Chiller Builder version 3.29. Please refer to the most current version of the Packaged Chiller Builder for the most up-to-date data.
