R124 and R142b as substitutes for R114 and R12B1

In place of R114 and R12B1 previously used in high-temperature heat pumps and crane air conditioning systems, HCFCs R124 and R142b can still be used as alternatives in most regions outside the EU.

With these gases it is also possible to use long proven lubricants, preferably mineral oils and alkyl benzenes with high viscosity.

Because of their ozone depleting potential, these refrigerants will only be an interim solution. In the EU member states as well as in some other regions, the application of HCFCs is no longer allowed. For R124 and R142b the same restrictions are valid as for R22 (R22 as transitional refrigerant). The flammability of R142b and the resulting safety implications should also be considered (safety group A2).
