【 摘 要 】

A performance analysis method for a centrifugal compressor chiller is developed. The source data used for the analysis are geometric parameters of the compressor stages, heat exchangers, refrigerant properties, and temperature regimes in the condenser and evaporator. The stationary mode is determined by iterative calculation as a point where the performance characteristics of the compressor, condenser, and evaporator cross. The methodology is tested using two refrigerants, R134a and R404a. The calculated performance characteristics for a two-stage chiller are presented.
