Which refrigerant is known for its low ozone depletion potential?

R-410A is recognized for its low ozone depletion potential because it is a hydrofluorocarbon (HFC) blend, which does not contain chlorine, a key element responsible for ozone depletion. In contrast, refrigerants such as R-22 and R-12 do contain chlorine; their use is associated with higher ozone depletion scores. R-134A, also an HFC, has a low ozone depletion potential but is not as environmentally friendly as R-410A in terms of global warming potential and overall efficiency in modern applications. R-410A was specifically developed to replace R-22 in air conditioning systems, making it a more sustainable choice for use in climate-friendly cooling technologies. The industry prefers R-410A not only for its minimal impact on the ozone layer but also for its energy efficiency and effectiveness in heat transfer.
