ShareGUIDELINES FOR SWITCHING CHILLERS OVER TO CFC-ALTERNATIVE REFRIGERANTS.
Type of article: Article
Summary
CENTRIFUGAL CHILLERS ARE BEING CONVERTED GRADUALLY TO R123, R134A AND R124 IN PLACE OF R11, R12 AND R114, RESPECTIVELY. IN THE FIRST CASE, ALL COMPONENTS OF COMMON NEOPRENES, SUCH AS GASKETS AND HERMETIC MOTOR INSULATION, MUST BE REPLACED. IN ALL CASES OIL MUST BE CHANGED TO A POLYALKYLENE GLYCOL OR ESTER-BASED LUBRICANT. IT IS ADVISED ALSO THAT EXTRA EFFICIENT PURGE UNITS BE FITTED TOGETHER WITH ALARM AND MONITORING SYSTEMS FOR LEAK DETECTION. D.W.H.
