Summary

HFO-1234yf has been functioning as a low global warming potential (GWP) replacement for HFC134a in refrigeration and air conditioning applications. Its viability has been proven as a pure fluid and in refrigerant blends. Once such blend is R-513A, an azeotropic blend of HFC-134a and HFO1234yf. A long term, continuous study on a commercial stationary refrigerator was conducted with R-513A refrigerant. The original HFC-134a refrigerant was replaced with R-513A in a 2-door commercial reach-in refrigerator and operated continuously for over 6 years. Energy usage and system parameters were continuously measured and compared to the original baseline operation with R-134a. The refrigerant and lubricant samples were collected for chemical and physical analyses and the compressor was removed for visual and metrology analysis. This paper reports the results of the longest continuous known test to date for R-513A in a refrigeration system, which will be used to validate the long-term viability of HFO refrigerants and R-513A in stationary refrigeration applications.
