摘要
探讨了滚动转子式压缩机容积效率的模拟问题。针对目前纯理论模拟方法的复杂性及不实用性等局限,采用了试验曲线模拟的方法。通过对经典性能关联式进行修正建立起一系列优化的性能关联式,依据大量有效的实验数据,运用多元非线性拟合方法求解性能关联式系数。结果表明,由该方法所建立的模型能够准确地描述变工况下滚动转子式压缩机容积效率等性能参数.
Focusing on the performance analysis of rolling piston type rotary compressor, a practical method of performance curve is used. New formulas for volumetric efficiency are created by optimization of the classical formulars, Multiple non-linear mathematical method is taken use of to get fitted coefficient. The results compare well with previous experimental data and can describe accurately the performance of compressor under variable conditions.
