The use of hydrochlorofluorocarbon (HCFC) type refrigerants ended and transitioned to non-chlorinated refrigerants in new OEM equipment. Concern now mounts over the replacements due to global warming issues. This seminar examines the drivers, current low global warming potential (LGWP) candidates, and their application and safety issues.
