R12

The following table shows the data for R12 and alternative refrigerants.

ODP: ozone depletion potential
GWP: global warming potential according to EN 378:2017; AR4: Fourth Assessment Report of the IPCC, AR5: Fifth Assessment Report of the IPCC, AR6: Sixth Assessment Report of the IPCC
pract. limit AEL: assigned exposure limit according to EN 378:2017
Temperature glide: Total glide from bubble to dew line, based on 1.013 bar. Real glide depends on operating conditions.
Relative refr. capacity and discharge temp. increase: Reference refrigerants are those listed under "Substitute for", performance data are average values based on calorimeter tests.
(H): high temperature application
(M): medium temperature application
(L): low temperature application
Data is based on publications of various refrigerant manufacturers and is subject to change.
