I have several R22 rotary compressors on stock, .5 to 1 Hp, outfitted with AB or MO oil.
Could I use them in medium or hi-temp refrigeration applications, using R22 or a different refrigerant?
For instance, I need a compressor for a very small walk in cooler, 34º to 40º box temp. The original compressor operated with R12. I could use R22 in this case, but do I have to change the evaporator and/or capillary tube?
I have no problems with a optional oil change if required.
Thanks -- Yall take care, walter.
