This session examines a variety of compressor technologies and their attributes in various applications, particularly investigations that include less ubiquitous and/or challenging refrigerants. These studies help the audience understand how to predict the performance of compressors and understand their behavior as the landscape of refrigerant types within systems becomes more stratified to include low-GWP refrigerants as well as increased system efficiency standards. Additionally, the audience has a better understanding of what work is being done on conventional compressor technologies, as well as the types of novel compressors and how they behave with low-GWP refrigerants.
