Type of article: Article

Summary

THE AUTHOR WARNS OPERATORS OF R11 CENTRIFUGAL WATER CHILLERS OF THE OZONE DEPLETION CHARACTERISTICS OF THE REFRIGERANT, AND THE NEED TO INHIBIT LOSS OF REFRIGERANT TO THE ATMOSPHERE BY IMPROVED INSPECTION AND SERVICING. UNITS ARE NOW AVAILABLE FOR REMOVING THE VAPOUR LEFT IN A CHILLER SYSTEM AFTER LIQUID HAS BEEN DRAINED TO A STORAGE VESSEL. THE SAME UNIT MAY BE CAPABLE OF CLEANING AND DEHYDRATING THE REFRIGERANT. ONE MANUFACTURER AT LEAST OFFERS COURSES TO TRAIN ENVIRONMENTALLY AWARE TECHNICIANS. R11 CHILLERS MAY ALSO BE OPERATED ON R123 PROVIDING A COMPLETELY ENGINEERED ADAPTION IS UNDERTAKEN, INCLUDING CHANGES IN GASKETS AND MOTOR WINDINGS. THE RESULT WILL BE A DECREASE OF ABOUT 15% IN CAPACITY UNLESS HEAT EXCHANGER PERFORMANCE CAN BE IMPROVED. NEW CHILLERS OPERATING ON R123 ARE ALSO AVAILABLE. D.W.H.
