The use of carbon dioxide as a refrigerant has grown in the residential, commercial and industrial refrigeration and heat pumping industries. This presentation will explore the different applications that have used carbon dioxide and will examine its efficiency as a refrigerant in different conditions. See below for details.

While reviewing subcritical and transcritical operation of a CO2 refrigeration cycle we will dispel myths about the efficiency of CO2 and understand which applications are best suited for its use as a refrigerant. The presentation will also explain the peculiar operation of systems operating with refrigerant above the critical point including the unique ability to increase compression ratio and efficiency at the same time.
