| description | In terms of the performance characteristics of a centrifugal chiller, a performance simulation algorithm was proposed using the iterative calculation of compressor power and condenser heat transfer in the range between the maximum capacity based on the maximum current and the minimum capacity with respect to surge. Thus, a performance simulation software for the centrifugal chiller integrating the heat transfer calculation of the shell and tube heat exchanger, performance calculation of the centrifugal compressor, and surge prediction was developed. The accuracy of the simulation model was verified using the prototype test results. The results indicate that within the entire load range, the maximum error of the COP is 6.43%; the maximum error of the chilled water pressure drop is 7.28%; the maximum error of the cooling water pressure drop is 4.45%; the maximum error of the power input is 6.87%; the maximum error of the evaporator saturation temperature is 3.83%, and the maximum error of the condenser saturation temperature is 1.24%. The simulation software successfully predicts various parameters, such as chilled water temperatures, cooling water temperatures, and flow rates of the centrifugal chiller under different loads. |
