Replacing a R22 based compressor with a R134a one
Hi,
I have a condensing unit that runs a compressor with R22 refrigerant. I want to replace that with a compressor that would work on R134a compressor. What changes (if any) should be done in the refrigeration circuit?
P.S. I understand that the expansion valve would have to be replaced.
Thank you.
