So propane is better than R134a? What about the R152a from electronics dusters? Just read a little bit on that and people are claiming better performance than R134a.

How do I tell if the TXV is adjustable? I thought they all were.

That one is an R22 labeled as -20 to 50*F. I'm assuming that's evap temperature. It's internal equalizer, is that acceptable or should I go for external for better efficiency? I was thinking about increasing evaporator capacity, either by adding the existing condenser as an extra evap or pulling the evap off of a larger A/C.

Edit: I see what you were saying, leave the condy in its physical place, then remove the squirrel cage and turn the system into a linear straight flow through with the original condenser replumbed in series before the original evap. Pull air through existing evap, over compressor, then out through condenser, right? That could work but I would have to do something with that original fan, it leaves a huge dead spot in the air flow right in the middle of the condenser.
