R424A refrigerant replacing R22

R424A refrigerant is an HFC refrigerant that has been used (retrofit drop-in) to replace HCFC refrigerant R22, which has been an extremely useful refrigerant gas for many air conditioning and cooling purposes in both consumer and industrial applications.

R22 was first introduced in the 1950s. – However, legislative restrictions were placed on its production and import in 2010, but maintenance use will be permitted until 2020.

R424A refrigerant  and other high GWP refrigerants soon prohibited

R424A is among the HFC refrigerants (hydrofluorocarbons, F-gases) that pose no threat to the ozone layer (ODP=0) but feature a high global warming potential. The GWP value of R424A is 2440.

The maintenance use of refrigerants with a GWP of > 2500 will be prohibited as of 1 January 2020 in the servicing and/or maintenance of refrigeration equipment with a charge size of at least 40 carbon dioxide equivalent tonnes.  Thanks to its GWP being less than 2,500, R424A is not among the banned refrigerants.

Banned refrigerants may no longer be added to systems starting from 1 January 2020. However, the maintenance use of reclaimed or recycled F-gases will be permitted up to 31 December 2029 (Article 13 of the Regulation). Reclaiming refers to processing used refrigerant in a treatment facility to be very nearly equal to original quality.

Applications and use

R424A has been used as a drop-in refrigerant to replace R22 in retail refrigeration systems and air conditioning systems.
