IMPACT ON FOOD REFRIGERATION OF OZONE PROTECTION LEGISLATION.

Type of article: Article

Summary

FOOD REFRIGERATION WILL RELY HEAVILY IN FUTURE ON R717 (AMMONIA) AND R22, BECAUSE THESE ARE NOT AFFECTED BY THE LEGISLATION. SOME IMPORTANT TECHNICAL DIFFERENCES DISTINGUISH R22 FROM THE MORE COMMON R12 PLANTS. THESE INCLUDE THE HIGHER DISCHARGE TEMPERATURE OF R22 AND THE POOR MISCIBILITY (MIXING) OF R22 WITH LUBRICATING OILS. METHODS FOR DESIGN OF R22 PLANT ARE DESCRIBED WHICH PREVENT OVER-HEATING OF COMPRESSORS, SEIZURE OF COMPRESSOR BEARINGS, AND LOSS OF COOLING EFFICIENCY IN EVAPORATORS.
