摘要： Design COP is iteratively computed. Provided is a centrifugal chiller performance evaluation system including a data acquisition section for acquiring operating data from a centrifugal chiller as input data; a storage section storing a design COP estimation formula obtained by adding correction values corresponding to losses occurring in an actual environment to a computational formula for ideal actual-machine COP expressed using COP characteristics of a reverse Carnot cycle; and a computing section for estimating a design COP at a current operating point using the operating data acquired by the data acquisition section and the design COP estimation formula stored in the storage section. The correction values include a first correction value calculated from a first computational formula including the load factor of the centrifugal chiller as a variable and a second correction value calculated from a second computational formula including a difference between cooling water outlet temperature and chilled water outlet temperature as a variable. The second correction value contains an offset from the first correction value depending on cooling water inlet temperature.

摘要： A calculating section 103 calculates a target COP that is a maximum COP that the centrifugal chiller can achieve using an arithmetic expression in which an actual device loss is given as a correction term to an expression that represents a COP characteristic under an ideal lossless environment. Since the arithmetic expression for calculating the target COP includes the heat exchange loss of the evaporator as a correction term, the heat exchange loss being calculated using a function having a load factor as a parameter, the heat exchange loss of the evaporator is reflected in the target COP.
