Unfortunately it will NOT be a drop in like R134a, operates at a much higher pressure, high enough that it requires additional sensors, and it is also mildly flammable, so leak sensors are also required.

Hmm...just proves that the whole game is bull*****. Ever heard of R-152a? The nearly split image of R-134a, but with a GWP of, oh, just 120 or so (which meets whatever that BS EU directive was)? Slightly flammable, yeah. About 15% more efficient than R-134a. Runs nearly identical pressures as R-134a, slightly lower discharge temps. Only downside is it makes nasty stuff if it burns (hydrogen fluoride), oh wait, that's the same stuff HFO-1234yf makes if it burns! I've converted R-134a circuits out of refrigerators to R-152a and it's great stuff, kicks butt for low temp applications, too. It's what all of the electronics duster cans use now. Why not just go with CO2? Refrigerant industry is always a conspiracy. What happens when CO2 is outlawed and we have to go back to the dark ages?
