摘要(Abstract):

根据离心式制冷机的特点,对丙烷系氟里昂物性进行了推算,并根据相应标准沸点范围,对26种丙烷系氟里昂进行了循环计算,提出了9种热力性能上比较有希望的R11的替代物,另外对丙烷系外的17种制冷剂也进行了筛选计算,认为在热力性能上,R123,R141b,R21,R133a是R11的比较理想的替代物。
This paper estimated the thermophysical properties of freons in propane family, and according to their corressponding normal boiling ranges, calcaulated the performances of 26 freons in propane famliy and proposed 9 thermophysically more promising substitutes for R11. Besides that, selections and calculations for 17 refrigerants outside of propane family were made with the conclusion that R123, R141b, R21 and R133a are thermophysically more ideal for substitution of R11 for further research.
