Hydrocarbon refrigerants as substitutes for CFC-12 in domestic refrigeration systems.
Author(s) : DRIESSEN J. L., PEREIRA R. H., THIESSEN M. R., LUNARDI M. A.
Summary
The authors present a theoretical analysis for determining the most suitable hydrocarbon refrigerants to replace R12 in current compressor design and in the capillary tubes of R12 refrigeration systems. They then present the results of performance evaluations of R600a and a 60/40 mixture of R290/R600a in a typical system originally designed for R12. For the tests the system components remained the same, except the compressor for R600a. Similar energy consumption was found for R600a as for R12; for the mixture it was about 18% higher. The results also showed that R600a performance could be slightly improved by adjusting the capillary tube. For R290/R600a, the necessity of optimizing the evaporator and the capillary tube was evident.
