Compressor for R290 rerigerant

[kay86]

Hi there, sorry to bother again. I've just seen a video on YT of a guy dismanteling his broken AC unit to repurpose its condensing unit for a R290 project. I was wondering if there could be dangers in doing so, other than the fact that the fan on a class A3 refrigerant unit should not provide sparks or ignition sources, if the pressure levels are fine, can it be used safely? I mean, it's just a pipe of copper with fins, why would it be different from other refrigerants?

Ahhh damn, I was supposed to say "Condenser" in the title, not compressor. I know compressors are very specific on the type of refrigerant and should not be swapped.

You can as you said use it for any refrigerant... mith the correct oil, compressor can run mostly on R290 as long as you do not overload the compressor motor ... a compressor is in fact just a simple gaspump

The copper condenser coil from an AC unit should be fine to use with R290. Just remember to leak check it, and maybe blow it through with nitrogen to try and get out any old oil.

Anyone who does some work on A type refrigerants should consider what are liabilities connected with that!
Just my opinion on matter!
