Type of article: Periodical article, Review

Summary

THE PAPER GIVES A DETAILED REPORT OF THE CURRENT POSITION OF CFC PHASE-OUT, SUBSTITUTION AND AVAILABILITY AND USE OF ALTERNATIVE REFRIGERANTS. TOTAL CESSATION OF CFC PRODUCTION HAS NOW ADVANCED TO JULY 1, 1997. THE MAJOR CFC REFRIGERANT USE HAS BEEN IN R12. THE SUBSTITUTE R134A, AFTER RIGID TESTING, IS NOW IN FULL PRODUCTION IN THE UK AND IS SUITABLE FOR RETROFITTING TO R12 SYSTEMS. SIMPLE TECHNIQUES ARE AVAILABLE FOR THE SUBSTITUTION OF BOTH REFRIGERANT AND THE NECESSARY ESTER BASED LUBRICATING OIL. TESTS INDICATE THAT THERE ARE NO ADVERSE EFFECTS ON EFFICIENCY OR COMPRESSOR LIFE. RESULTS OF ASHRAE SEALED TUBE TESTS ON ELASTOMERS ARE GIVEN. COMPATIBILITY OF R134A WITH METALS IS GOOD. A SYSTEM CAPACITY DECREASE OF ABOUT 10 % IS THE ONLY DRAWBACK. ALTERNATIVES TO R22 AND R502 ARE UNDER DEVELOPMENT. PROPERTIES OF CFCS AND SUBSTITUTES ARE GIVEN. D.W.H.
