摘要
本文针对我国制冷工程中广泛运用的一级节流中间完全冷却双级氨压缩循环,给出了运用电子计算机选择压缩机的程序设计结构和应用举例。文中采用最大制冷系数时的中间温度为最佳中间温度,能列出设计工况下可选择的最节能的双级压缩机或高低压级配组机的“菜单”,供设计者从中选择最满意的机器。
In view of the ammonia compression circulation of doublestage of the complete middle cooling in one-grade saving flow, widely used in refr igerat ion engineercing in our country, this article presents the stracture of design of programs of compressors and the application examples selected by electronic computers. The middle temperature in the biggest refrigeration coefficient used in the srticle is the beat temperature. It is possible under the design engineering condition to make a 'menu' of the most energy-saving double-stage compressors and the group-fitting compressors,with high or low pressure grade in which the designer can choose the most satisfactory machine model.
