摘要
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 卤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.
