Only if they run similar pressures. R-22 is basically the same pressure as R-290 (propane) but all the newer stuff is much higher. I think that means it ends up icing over really quick.
- SoftTalker 4y agoA propane/isobutane blend is a good replacement for R-12 which was the refrigerant used for air-conditioning before CFCs were banned. Straight propane as you note is better for freezers than air conditioners. A problem with blended refrigerants is that if there is a slow leak the blend will change as the refrigerant leaks out, due to the different partial pressures. That makes recharging more difficult, you basically have to vacuum out the system and recharge with the correct mixture. Also, propane and isobutane are both flammable, but other than CO2, most refrigerants are to some degree.
- Aloha 4y agoSome of them produce quite nasty byproducts when they burn too.
- coryrc 4y agoErr, my last statement refers to what I think happens if you replaced R410a with R290 without further changes.
