R410A refrigerant is a blend of HFC-like substances that does not contain any ozone depleting substances and has an ODP value of zero. However it has a high Global Warming Potential (GWP), 1725 times that of CO2, which is similar to R-22. Compared to R22, R410A has a significantly higher cooling capacity and therefore offers the possibility of designing smaller and more compact air conditioning units. And because of its near azeotropic properties, the refrigerant temperature slip is less than 0.2°C over the entire operating range and R410A does not undergo significant separation in refrigeration and air conditioning systems, i.e. no change in refrigerant composition due to leakage, so that the remaining refrigerant in the system does not need to be discharged during after-sales service recharge. R410A is recognised worldwide as a medium to long-term alternative to R22 refrigerant in domestic air conditioning.
