    Confused Propane based R22

    I have a customer that wants me to charge his HP with propane based R22. I have never heard of this refrigerant. He says he has used it and can get it cheap. I don't like the sound of it. Sounds dangerous to me. What is it?

    Is it the same refrigerant that's used in RV reefers?

    I never heard of it either. I always supply my own refrig. and use what the manufacture recommends. I would tell him if he wants it charged with that, then he can do it.

    Tell him no. The propane based refrigerants are not legal to use in home comfort cooling systems.

    R290, BBQ fuel basically, just dehydrated.

    Widely used in Europe and Australia.

    Yeah, don't do it. A guy like me may come along and pump the unit down to replace the indoor txv and kaboom!!!!!

    There are a number of hydrocarbon blends out there for R-22, including plain old propane. You cannot legally retrofit a unit in the U.S. with a hydrocarbon refrigerant.

    Have built small experimental units with BBQ propane, ran thru a drier, work great with R22 txv/scroll compressor. Water/water unit outdoors where any R290 leak can flow downhill.

    One of the safety concerns to remember is that the drier removes the percaptan as well as moisture so no aroma/smell to indicate a leak.

    Anything anybody here builds never leaks anyways, eh?

    One way to outthink people is to make them think you think. They'll think you're not really thinking what you're trying to get them to think you think...........

    We had a class the other day on new R22 replacements and the guy giving the class from Honeywell said the environmental nuts are pushing this hard at the EPA. He then showed us a demonstration video of a House Refrigerator charged with propane. They simulated a small leak and the defrost timer cut in and guess what!!!!! BBBOOOOMMMMMMM
    One Hell of blast, blew the door completely off and sent the ice bin flying in the air. Not in my house!!!

    I am not going to use it. I do keep several types of refrigerant on my truck and propane is not one of them.
