Abstract
A method of evaluating performance of a chiller is provided. The method includes detecting a plurality of operating parameters of the chiller with a plurality of sensors. The method also includes individually determining a first coefficient of performance degradation due to condenser fouling. The method further includes individually determining a second coefficient of performance degradation due to condenser water flow reduction. The method yet further includes individually determining a third coefficient of performance degradation due to evaporator fouling. The method also includes determining a total coefficient of performance degradation of the chiller with a summation of the first, second and third coefficient of performance degradations.
