摘要
采用非线性二乘法对国产12.5系列往复活塞式制冷压缩机的实测性能数据进行拟合,得出描述该系列制冷压缩机性能系数与运行工况之间相关关系的曲面回归方程,为制冷系统的数值计算、动态特性模拟和优化设计提供数学模型。
The response surface regrssion equation,which describes the conflation between cofficient of pthermance of native reciprocating compressor serice 12.5 and working conditions, is obtained by means of fitting measured characteristics data of the series with nonlinear least square method, which Provides numerical calculus, dynamic analog and otimal design in refrigerating System with mathematical model.
