for me the only solution to be rid of this gas problem is R297 ... quite simply propane
the good heat pump of the future should be rustic enough to accept ordinary propane sold as fuel, and not need R297 which is purer
andré your pump is what type? water / water?
it is obvious that we cannot put propane in a split which circulates the gas inside the accommodation
the R297 also requires changing the oil: you need a simple mineral oil with high viscosity which becomes more fluid a little diluted by propane ... the compressor manufacturers know which oil to use

If it is a water / water group to run on R297, everything will have to be changed (complete group). The R22 regulator will not work. There are all kinds of organic refrigerants including ammonia. We come back to it more and more. At the moment Co2 is in vogue. All for use with heat transfer fluids.

I also know CO2 and ammonia
the problem of C02 is that it works at much higher pressure, so completely different equipment
ammonia is not compatible with the same materials
propane replaces freon and is compatible with most compressors, with the right oil ... of course a capillary regulator will not have the right setting, you have to put an adjustable regulator
