Abstract
The article deals with retrofitting turbomachinery of 10ТХМВ-4000-2 type from R12 refrigerant to R142b/RC318 (0.42/0.58) to azeotrope mixture with out changing mineral oil. Refrigeration equipment of CVGD-39 type by TRANE company was used to retrofit R12 to R134 and to Jekohol HFC mixture (0.05R600a/0.95R134a). R134 with synthetic oil was used at the first stage. Jekohol HFC mixture (0.05R600a/0.95R134a) was proposed to retrofit refrigeration equipment without changing mineral oil, itsapplicability being checked experimentally.
