I live in usa, R12 is very very expensive($20/lb).
R22 is very cheaper only $3/lb.
i replaced my ตู้เย็น with R22, i worked but high side pressure is very high 300lb/inch. the compresser have to be replace with a larger one.
i added a extra cooling fan to reduce head pressure.
and it's working fine.
the benefits are freezer is very cold -15 degree C
icecream is hard like a rock.
