Environmental tradeoffs between CFCs and alternative refrigerants.

Summary

The paper makes the point that in developing substitute refrigerants with lower ozone depletion potentials than CFCs, the total effect on global warming may be overlooked. Whilst substitutes may themselves have lower greenhouse effect if released to the atmosphere, they may be less efficient refrigerants, thus increasing CO2 emissions when additional refrigeration input power is generated. A number of comparisons are made using the estimated average from usage data of 17.5% annual loss from centrifugal chillers. Even with such a high loss, caused probably from inefficient purge operation, the substitute R123 compared with R11 still produces an overall fall in greenhouse effect of about 330 kilograms CO2/year per ton of refrigeration.
