Abstract
A calculating sectioncalculates 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.
