Abstract: R-22 (also known as HCFC-22) is one of the most widely used refrigerants in U.S. Army air-conditioning and refrigeration (AC&R) systems since the phase-out of R-12 refrigerant in 1995. The need to phase out R-22 is attributed to its global warming potential and high ozone-depleting capability. The U.S. Army has tens of thousands of aging AC&R systems that will remain dependent on R-22, or one of the recently developed substitutes for R-22, until they reach the end of their operational life. This project conducted a survey to understand the current R-22 usage and types of R-22 AC&R equipment that are in use across U.S. Army Installation Management Command (IMCOM) installations. This study describes several methods to remove or retrofit R-22 from typical AC&R equipment and implementation strategies to meet the stated goal of eliminating R-22 from IMCOM installations. The scope of this project included the review of BUILDER SMS data for IMCOM installations, which included data on 13,000 pieces of comfort cooling equipment for 31 installations. The report also provides an analysis of several R-22 alternatives and their physical properties and compatibility. Mission critical tactical cooling that uses R-22 refrigerant was not within the scope of this project.
