R12离心式冷水机组替代制冷剂LXR2a的泄漏分析

Leakage Analysis on a Refrigerant Alternative LXR2a to R12 in Centrifugal Chillers

对LXR2a进行了泄漏模拟和泄漏—再充灌模拟分析。分析了这两个过程引起的摩尔质量以及循环性能的变化 ,结果表明在泄漏以及泄漏—再充灌过程后 ,LXR2a的摩尔质量仍符合离心式压缩机的要求 ,只是冷量将可能有所降低。

Leakage simulation and leakage recharge simulation are done and the changes of the mole weight and cycle performances of LXR2a are analyzed. It shows that the change of the mole weight of LXR2a satisfies the special requirement of centrifugal compressors, but the capacity of chillers using LXR2a will decrease a little.
