Low GWP flammable refrigerants
AREA, the European organisation of air-conditioning, refrigeration and heat-pumps contractors, has published a guide on equipment for low-GWP flammable refrigerants. It gives service technicians a tool to understand the equipment that should be used to service refrigerant plant containing flammable low-GWP refrigerants in category A2L (lower flammability) or A3 (higher flammability).
Alternative refrigerants to HFCs will be increasingly used as a result of the new EU F-gas Regulation and the probable future international phase-down of substances with high global-warming potential.
The guide is the result of work undertaken by the AREA task force on low-GWP refrigerants.
