Refrigerants with ‘22a’ or ‘R-22a’ in the name contain highly flammable hydrocarbons
May 30, 2016
The U.S. Environmental Protection Agency (EPA) is again cautioning homeowners, manufacturers of propane-based refrigerants, home improvement contractors, and air conditioning technicians of the safety hazards related to the use of propane in existing motor vehicle and home air conditioning systems.
In March, the EPA approved several low-GWP hydrocarbon refrigerants for use in refrigeration and air conditioning applications, subject to use conditions. The approval drew a mixture of reactions ranging from support to concern.
Now that the Environmental Protection Agency (EPA) has greenlighted the use of a number of hydrocarbon (HC) refrigerants in certain refrigeration applications, many in the industry have questions about these refrigerants and their potential uses.
