RESTON, VA — A survey of large tonnage liquid chiller manufacturers by the Air-Conditioning and Refrigeration Institute (ARI) revealed that by the end of this year, approximately 40,560 of the estimated 80,000 CFC-using chillers in service in the early 1990s will still use CFCs.
At this pace, ARI estimates it will take until the end of this decade to eliminate chillers that use CFC-11 and CFC-12, the two most widely used CFC refrigerants.
