Review of regulations and standards for the use of refrigerants with GWP values less than 20 in HVAC&R applications. Final report.

This report presents the results of a comprehensive review of the regulatory issues in the United States, European Union, and Japan that are relevant to the application of emerging low-GWP refrigerants. Specifically, this report focuses on regulatory barriers and issues that may impact the use of CO2, ammonia, hydrocarbons, and lower-flammability fluids such as HFO-1234yf. Within each region, the categories of stationary refrigeration, stationary air conditioning, and vehicle air conditioning applications are addressed. It also provides recommendations on research or other activities that might be advisable in order to remove barriers to acceptance of low-GWP refrigerants.
