R-410A is considered to be a non-ozone depleting refrigerant. When compared to R-407C and R-22, this refrigerant provides better energy efficiency. It doesn’t contain chlorine and is a much better option than R-22.
NettetA2L refrigerants need at least 1,000 times more energy to ignite than most A3-class flammable refrigerants. It means that A2L refrigerants are unlikely to ignite from a discarded cigarette or a space heater. Even naked flames struggle to ignite A2L refrigerants under test conditions. What’s more, the “L” means they have a low burning ...
