ARLINGTON, Va. — Building owners who use ozone-depleting CFC refrigerants in chillers for comfort cooling in buildings replaced or converted only 4,231 units in 1998, according to a survey of chiller manufacturers released by the Air-Conditioning and Refrigeration Institute (ARI).
At the current pace, it would take until 2010 to eliminate use of CFC chillers in the United States, despite a ban on the production of CFCs that went into effect on December 31, 1995. Approximately 52,060 chillers, 65% of the estimated 80,000 CFC chillers in service in the early 1990s, required CFCs to remain in service at the start of 1999.
