Converting Centrifugal Chillers to HCFC-123

This paper describes the effect that the issue of ozone depletion has on the owners and operators of large commercial water chillers that currently use chlorofluorocarbons (CFC's) for refrigeration. The production ban of CFC's mandated by international law will eliminate production on January 1, 1996. The actions taken by owners and operators of large water chillers will depend upon a variety of factors that will be addressed. This paper will also document the actions taken by three owners of large water chillers in addressing the CFC issue. These owners, for a variety of reasons, chose to address the issue through the conversion of the existing equipment to an HCFC refrigerant. For each of the three owners, the option of converting the existing equipment was the most cost effective and also the most practical option
