The environmental aspects of refrigerants and refrigeration systems.

Author(s) : BRUINSMA M. H.

Summary

Ammonia can serve as an alternative to R22, but it requires the use of an indirect system. The author presents yet another alternative, mixture composed of R22 (23%), R125 (25%) and R134a (52%). Its only consequence for the design of the refrigerating system would be an increase in compressor motor size of 3%. Although the new refrigerant is more expensive, a direct expansion system would still be substantially less expensive than an ammonia brine system. There would also be less effect on the environment, given the higher efficiency of the direct expansion system. The requirements for conversion are minimal. A laboratory test was conducted with encouraging results. The new refrigerant is suitable for both new buildings and for retrofitting existing reefer vessels, and constitutes a long-term alternative.
