In my argument for BBq propane gas with AtomTrainer, I did not hound this point. However, since it has come up, R1270 (propylene) is another outstanding natural refrigerant. It can be used in the same way as R290: to replace R22 with no major system modifications. It is also the primary contaminant in BBq gas bottle propane. For ordinary experimental use, its properties are very close to that of propane. Pure R1270 is marketed by gas2010 as Care 45.


dc€x,
The bottles of map gas (propylene) that I use have the same fittings as propane bottles. As such, HV23T has a good pic of the type of adapter I use to charge and recover small amounts of refrigerant. See this thread:

The pic is in post #3.
