That's correct! Refrigerant 410a, also known as R-410a, is a hydrofluorocarbon (HFC) refrigerant commonly used as a replacement for R-22 in residential and light commercial air conditioning and heat pump systems. It has become the leading choice for such systems due to its high cooling capacity and significantly higher pressure compared to R-22. Additionally, R-410a is considered to be an environmentally friendly option as it does not contribute to ozone depletion. This is in contrast to R-22, which is a hydrochlorofluorocarbon (HCFC) refrigerant that has been phased out due to its harmful effects on the ozone layer. It's important to note that R-410a should only be used in systems that are specifically designed for it, as it operates at much higher pressures than R-22. However, equipment designed for R-410a can provide up to 60% greater capacity than current R-22 equipment, and air conditioning systems using R-410a can meet or exceed local energy performance guidelines.
