Investigation of using a ternary mixture as alternative for R12.

Author(s) : CANREN L., ZHAO Y., YITAI M.

Summary

The paper investigates the effect using the ternary mixture of R22/R152a/R142b as substitute for R12. According to measurements made the vapour pressure curve of the mixture, for a certain composition, is very close to the curve for R12. A test proved that the ternary mixture under a certain concentration is a near-azeotropic mixture. It is shown that the ternary mixture has more capactiy, lower discharge temperature and higher COP than R12. For the above reasons the mixture may be expected to become an alternative for R12 with the goal of suitability for equipment originally designed for R12, therefore it should be investigated further.
