System for analyzing and comparing current and prospective refrigeration packages

摘要

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. The computer system and related hardware are provided, including that necessary to process and communicate the results of the analyses and monitoring to onsite displays, printers, data storage, and remote terminals and computers.
