With ever stricter European F-Gas regulations on high GWP refrigerants, new solutions are emerging in the refrigeration and air conditioning market. With lower GWP but slight flammability, these refrigerants can be used in many applications and processes, as were HFC/HCFC refrigerants, whilst complying with current legislation and recommendations related to their low flammability.
To date, the A2L refrigerants may only be used in new equipment intended for this purpose, or used in systems specifically designed to operate with these products. Under no circumstances should a system operating with a non-flammable refrigerant be retrofitted with a flammable refrigerant without study, prior requalification and authorisation, in order to remain in compliance with applicable regulations.
