System for analyzing and comparing current and prospective refrigeration packages

A method for economically analyzing the performance of an operating first chiller with respect to the hypothetical design rated performance of at least two other chillers, the method comprising the steps of:

• (a) for the first chiller and for each of at least one designated time periods, obtaining at least one set of real tonnage derivation data, real power usage data, and cost per unit of power data;
• (b) obtaining other chiller information, including design rating information for at least two of the other chillers, the design rating information for each of the at least two chillers including the design rated power requirement;
• (c) deriving the power cost difference to operate the first chiller compared to the operation of at least one sequenced combination of at least two of the other chillers;
• and
• (d) economically differentiating the future use of the first chiller with respect to the hypothetical future use of the at least one sequenced combination of the at least two other chillers.

A computer readable medium containing program instructions for execution on a computer system, which when executed by a computer, cause the computer system to perform method steps for economically analyzing the performance of an operating first chiller with respect to the hypothetical design rated performance of at least one other chiller, the method comprising the steps of:
