Summary
A MAJOR UK REFRIGERANT MANUFACTURER IS PERFECTING A SIMPLE PRO CEDURE FOR REPLACING R12 WITH R134A IN COMMERCIAL REFRIGERATION AND AIR-CONDITIONING SYSTEMS. BECAUSE OF THE POOR SOLUBILITY OF R134A IN MINERAL OILS, IT IS ESSENTIAL THAT LUBRICATING OIL BE REPLACED BY AN ESTER-BASED OIL. IT IS ALSO NECESSARY TO REPLACE EXISTING EXPANSION VALVES AND DRIERS WITH THOSE COMPATIBLE WITH THE NEW REFRIGERANT. A SUCCESSFUL PROCEDURE IS DESCRIBED WHICH, PROVIDING THE AMOUNT OF R12 IS REDUCED TO BELOW 200 PPM AND THE REMAINING MINERAL OIL QUANTITY IS SMALL, SHOULD GIVE SATISFACTORY PERFORMANCE. D.W.H.
