R32 is being introduced as a replacement for R410A in new equipment, but is not suitable for use in existing equipment because it is flammable. R470A meets this requirement as a retrofit solution being non-flammable, low toxicity and with similar cooling capacity, pressures and Coefficient of Performance as R410A.
R470A has a similar thermodynamic performance with matching energy efficiency and cooling capacity as R410A. It is suitable to be used to replace R410A in existing equipment, being compatible with materials commonly found in these installations. It contains components that are known to have excellent chemical stability in air-conditioning equipment and have well-established low toxicities.
R470 is an exciting new development in the quest to replace higher GWP refrigerants particularly, although not restricted to, existing equipment. It enables users to replace R410A with minimal changes and inconvenience at low cost and is compatible with lubricants typically used with R410A so that there is no need to change the existing lubricant in the system when retrofitting.
R470A is an excellent option to replace R410A, especially in the European Union where F-Gas regulations are creating shortages, but also in other countries which are also introducing restrictions on the sale and use of refrigerants containing hydrofluorocarbons.
