I can see how LPG could work as a refrigerant... The numbers look
about right... If the LPG has the odorant added to it, you would
quickly know if there was a leak and it was getting into the passenger
compartment... It would be noticeable quite a bit before it got into a
flammable concentration... Anything less that 2.2% or more than 9.5%
is not flammable... All in all, LPG is a relatively safe gas...
Hydrogen, on the other hand, is flammable from 4% to 75%... Not really
important from an A/C refrigerant standpoint, but important from a
standpoint of eventually using it in vehicles as a replacement to
gasoline... A lot of the fix-a-flat type devices use propane / LPG as
the gas to refill the tires with... Since LPG has such a narrow
flammability range, it would be pure luck if you happened to end up
with a tire that had a flamable concentration in it...
