What major advantage does R-410A refrigerant have over R-22?

R-410A refrigerant is recognized for being less harmful to the ozone layer compared to R-22. This advantage is critical in the context of global environmental standards and regulations. R-22 contains hydrochlorofluorocarbons (HCFCs), which are known to deplete the ozone layer, contributing to environmental damage. In contrast, R-410A is composed of hydrofluorocarbons (HFCs), which do not have ozone-depleting properties. This significant reduction in environmental impact aligns with initiatives to phase out ozone-depleting substances, making R-410A a more environmentally friendly option for cooling systems.

Together with its safety for the ozone layer, R-410A also supports sustainability in HVAC practices, especially as industries move toward greener alternatives.
