摘　　要：本文以R134a为工质,在忽略泄漏和润滑油对压缩过程影响的情况下,给出了涡旋压缩机非稳态压缩过程模型。并用四阶Runge-Kutta法同时求解以曲轴转角为变量的相关方程式,对涡旋压缩机压缩过程中气体工质温度、压力和容积的变化进行了模拟计算。结果表明,模拟计算出的数据是合理的。该模型可以用来模拟涡旋压缩机非稳态工作过程。While refrigerant R134a is the working fluid,an unsteady state model for the compression process of a scroll compressor was presented in this paper.It is assumed that there is no leakage across the seal surfaces and the existence of the lubricating oil is neglected.The fourth-order Runge-Kutta method was used to integrate the relative equations for the instantaneous refrigerant states as a function of the orbiting angle.The instantaneous temperature,pressure and volume were obtained.The results indicate that the calculated data are reasonable,and this model can be used to calculate the instantaneous compression process in a scroll compressor.
