摘要
主要讲述了带两路旁通系统的三级自动复叠制冷系统的搭建,采用美国标准技术研究所(NIST)开发的REFPROP 8.0程序计算混合工质的热力性质并确定混合工质的成分及配比。在此基础上,通过实验研究旁通管路对系统吸排气压力、温度以及降温特性的影响,以期能找到一种适合自动复叠制冷系统的有效的调节机制。
tins mesm was malnty about the construction ot tile three -stage auto- cascade retngeratlon system with two by - passes. The REFPROP 8.0 developed by NIST was applied to calculate thermodynamic properties of the mixed refrigerant and determine the components and proportion of the refrigerant. In order to find an effective control mechanism suited to auto - cas- cade system, further experiments were conducted to find how the by -pass influenced cooling performance and the pressure and temperature of compressor suction and exhaust.
