摘要
在制冷工程设计过程中,传统的压缩机选型计算过程复杂,涉及到大量数据资料的查询,耗时较长,误差较大,影响选型的准确性及微机的应用。因此,可利用最小二乘法原理,将各种型号压缩机的性能曲线拟合成公式,从而提供一种更简捷、更高效的压缩机选型新方法。
Type selection of the traditional compressor is complicated which takes much time, and the selection accuracy is relative low. It is hard to select compressor by computer. Using the least square method, simulates the compressor characteristic curves into the formulas for type selection. Offers one briefer and more high-efficient type selcction method of compressor.
