Is it the same refrigerant that's used in RV reefers?
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!!!!!
I'd want to talk to his insurance agent, and YOURS before I even bought that stuff.

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?
Armaflex will cover that leak for you hehe
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.
The problem with some blended refrigerants is they have a different glide....meaning in the event of a leak, all the other ingredients may leak out leaving you with pure liquid propane. This stuff makes big fires!
propane does have the same boiling point at r22 but its just a lil more combustable.
Propane for all your heating AND COOLING needs!why didnt i think of that?
what happens when the compressor shorts out internally and obviously makes sparks will it blow up???? or not since you need oxygen, i think it will still go
kaaaaboooom???? honestly its messed up think about it you have these hacks throwing it in these systems then here you go replace txv under normal procedures starts a huge fire now its on your insurance company, kind of not fair gotta becareful out there.
Propane's explosive limits are 2.37%–9.5%. It will not explode below or above these concentrations. It is very common as a DX refrigerant in household refrigerators in other countries and has been for a long while now. The amount required is only a few ounces. It is also widely burned in gas absorption refrigeration systems, so it really can heat and cool!
Correct it needs oxygen to blow. When my reclaim machine failed last week it blew out a mist of refrigerant. Pretty sure that would have been a fireball with propane.
