This is a very basic walk-in box - 1 1/2 HP TPCo tin can originally on R-12 - now using R-414B. It has a bad compressor at the moment. The customer has a row of A/C units sitting along with this one high-temp refrigeration condensing unit.
My original thought was to change to an R-22 valve and install an R-22 compressor as the replacement.
My question is: will the original R-12 condenser coil be sufficient to reject the heat properly while using R-22?
