High efficiency R22 replacement.

Author(s) : ROBERTS N. A., PEARSON S. F.

Summary

There are no single component refrigerant replacements that have the complete range of advantageous properties of the ozone-depleting, CFC and HCFC refrigerants. Furthermore, it is unlikely that new materials having these properties will be discovered. Therefore, for many applications, it has become necessary to use blends, since these offer a means of attaining almost all the previous advantages. This paper discusses the relevance and usefulness of blends to the present situation and specifically addresses replacement of the ozone depleting refrigerant R22 with a zero ODP alternative, compatible with polar and non-polar lubricants. The vapour pressure of the blend is given revealing that at elevated temperatures the condensing pressures of the blend are lower than for R22 at the same temperature. Results are shown from a series of calorimeter tests, confirming the refrigerating performance of the blend is similar to that of R22 and the efficiency is higher than when R22 is used. The blend is non toxic and non-flammable.
