Abstract:
A method 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:(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 each of the other chillers, the design rating information including the design rated power requirement; (c) deriving the power cost difference to operate the first chiller compared to at least one 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 other chiller.
