摘　　要：为解决实际化工生产中各生产单元、工艺过程对不同品级冷量的需求,本文将不同的压缩制冷循环过程归纳综合成一种通用的过程,并基于物料衡算、能量衡算建立通用的数学模型,开发了可以模拟计算压缩制冷循环过程的计算机软件。通过实例表明通过该软件程序可以计算系统各单元的冷剂的热力学性质、流量及换热单元的冷负荷,为过程动力、冷量等的分配提供参考数据,对实际生产具有重要的指导意义。Based on in chemical manufacture in practice, different units and technical processes need different level cooling energy, the paper concludes different compressed refrigeration circulations to synthesize a general process and establishes the general mathematic model based on material and energy balance, empoldering a computer software which can simulate and calculate compressed refrigeration system. Examples show that the program can calculate cryogen＇s qualities, flux of each unit and cooling burthen in the system, providing process power, cooling energy, with reference datum. It has an important instructional effect to practical produce.
