Estimating partial-load performance of centrifugal chiller is very important to operate a heat source system in high efficiency. In this paper, we show a method of calculating the partial-load performance for fixed-speed chiller and iiriable-speed chiller. The method is flamed by simple equations derived from thermodynamics and fluid dynamics of centrifugal compressor. The performance at various operations can be calculated by the method (partial-load ratio, cooling water temperature, chilled water temperature). Accuracy of the method is compared with measurement performance data. Furthermore, the method will be applied for a control board of chiller and a simple simulation which consists of Excel spreadsheets.
