IIR documentSummary
A performance predicting model of screw compressors, for refrigeration system simulation, is developed. The model correlates the running condition and some of the design parameters of a screw compressor. Compared with the experimental data, the errors of the model predictions are about ±2% for the volumetric displacement, less than 3% for the input power at full load condition, about 4% for the input power at part-load displacement condition, and about 2% and less than 4% for vapor injection mass flowrate. This model can also be used to optimize the built-in volumetric ratio of a screw compressor.
