Enviro-Safe Refrigerant

[bigjimmy]

Has anyone used this refrigerant?

It seems too good to be true. It's basicly a propane and butane mix. Performs better, costs less, better for the environment, but possibly more flammable.

Here's a link

I feel sorry for the poor mechanic smoking cigarettes while working on one of these ac systems charged with this!

Oh yeah, lets put explosive gases in our AC systems!

Go with Freeze12. Works great.

F12 is 80% R134a and 20% R142b

So it will perform most like R134a except for flammability of R142b

The main problem is the Q variable displacement is suction pressure set for 28 psi whereas F12 need 20-19 psi and an internal recalibration of the compressor or just live with a 20% decrease in peak performance.

R134a alone would boil at 32F vs 29F for R12 and the F12 mixture as high as 38F.....................................see chats in middle of last pdf.

F12 is colder in practice than R12 and much colder than R134a. I dont know why.

Maxnix drinking during the day again huh.

They are not explosive gases, they are flammable and pretty much any gas under pressure mixed with oil is flammable.

Just Google refrigerant fires and you will find R-12 and R-134 burn too.
