螺杆制冷压缩机性能预测与试验对比

The Performance Prediction with the Test Contrast on Screw Compressor for Refrigeration

通过建立的喷油螺杆压缩机工作过程的数学模型,并考虑了制冷工质的真实性与油中溶解度等因素,进行了模拟计算,通过试验与模拟结果对比,证实了数学模型及性能预测的可靠性与实用性。

By means of established mathematical model of working process Of oil-injected screw com- pressor,which has considered reality and solubili- ty in oil of refrigerant,the modelling calculation is carried out.By way of contrasting the results of modelling with the test,the reliability and practi- cability of mathematical model and performance Prediction has been verified.
