Physical properties of R-410A refrigerant

R-410A is a blend of two refrigerant gases, namely difluoromethane (R-32) and pentafluoroethane (R-125). It has a molecular weight of 72.58 g/mol and a boiling point of -51.5°C (-60.7°F) at atmospheric pressure. Its critical temperature is 72.5°C (162.5°F) and its critical pressure is 4.96 MPa (719 psi). R-410A has a low ozone depletion potential (ODP) of 0 and a high global warming potential (GWP) of 2088, making it a popular choice for air conditioning systems. It has good thermodynamic properties and is compatible with many lubricants used in refrigeration systems.
