Comparing R-134a Chillers versus Packaged Ammonia Chillers for Air-conditioning Applications (2003)-Packaged ammonia chillers (PACs) are similar to R-134a chillers. Both are factory-assembled refrigeration systems that use conventional refrigeration drivelines. PACs are becoming increasingly popular for non-air-conditioning applications. In this paper, the author analyzes ammonia's competitiveness in the water-cooled screw chiller air-conditioning market and discusses lifecycle costs, first costs, current technology, and provides some insight into future technologies.
