Abstract: A system provides the operator of a refrigeration package, such as a water-chilling package, with both short term and long term economic and quantitative analyses of the operating chiller, comparing the existing performance to the hypothetical design rated performance of other chillers, using actual operating conditions and parameters. The system performs such analyses using either historical evaporator tonnage and actual power usage data, or works in real time to provide a “snapshot” economic forecast, based on the immediate conditions. During real time monitoring of various performance data, the system can also identify unsatisfactory performance conditions, i.e. faults, and provide the operator with onsite information as to the possible causes of, and potential solutions to, the unsatisfactory condition.

Abstract: A system is provided that provides the operator of a refrigeration package, such as a water-chilling package, with both short term and long term economic and quantitative analyses of the operating chiller, comparing the existing performance to the hypothetical design rated performance of other chillers, using actual operating conditions and parameters under which the existing package operates. The system economically differentiates the future use of the existing chiller with respect to the future use of one or more prospective replacement chillers. The system performs such analyses using either historical evaporator tonnage and actual power usage data, or works in real time to provide a “snapshot” economic forecast, based on the immediate conditions. During real time monitoring of a wide variety of performance data, the system can also identify unsatisfactory performance conditions, i.e.
