Hi,
Just after some advice, i am restoring a 1950's fridge that was on R12, i have had to retrofit a new compressor as the old pancake was dead, I only have access to R22 at the moment and was wondering if i charged to the frost line on the evap if it would still run ok? i realise that i will have a very high back pressure compared to 134a but i am just dieing to test the new compressor out.
I realise that domestic fridges don't use R22 but i just can't see why not? the compressor is rated for R22 and i can't see any pipework issues with around 100kpa on r22 apposed to 40kpa on 134. will i have head pressure issues or a heat removal issue with the higher head pressure associated with r22 and the condenser only being sized for r12?
any help would be great
