One presentation will compare HFC-134a chillers and packaged ammonia chillers for air conditioning applications. The report will analyze ammonia’s competitiveness in the water-cooled screw chiller air conditioning market. Another presentation will focus on R-134a and ammonia, looking at case studies of two plants and how the fundamental thermodynamic properties of the two refrigerants affect the design of real-world refrigeration systems.

The ammonia industry has been looking at ammonia used in conjunction with CO2 in cascade systems, and a report at the conference will examine the quality control involved in installing and commissioning such a system. The methodology involves a Technical Installation Risk Analysis (TIRA) that helps the project manager ensure the quality of an installation while addressing practical installation issues.
