New Refrigerant: Difluoroethane

[Dr_Snooz]

Apparently you can use canned air from Wal-Mart to recharge your A/C. Anybody heard of it? Anybody tried it? Propane is awesome, but it won't work in my truck without some additional retrofitting. I may give this a whirl.

Here's some background for those interested.

I've heard about it and plan on trying it when I reinstall AC into my 3gee. A can side tap is all you need to purchase if you already have the manifold gauges and a vacuum pump.

I actually just charged mine with it today. 38-40 degree vent temp when moving, 45 at idle at a stoplight. Correct charge is 55% of the original r12 charge, so since ours take 28-32 oz, correct charge is between 15.4 and 17.6 oz, basically two 10 oz cans since some is lost in the gauge set and during connect/disconnecting hoses plus what remains in the can.

It was around 64 degrees on this test, so I will update later in the summer on how the performance is. I plan to install r12 once I'm confident the system is not leaking, but than probably won't be for awhile.

Is there any kind of conversion to be done? Is difluoroethane (R156) compatible with all A/C oils?

[zenapup]

R152a is the same as 134a in regard ro oils, compatible with PAG and ester oil, but not mineral. Otherwise, no conversion is necessary.
