Changing from 507 to 22 in a cold store.

[babs jolayemi]

Hi members, kindly help in advice on changing a cold store of 1200 metric tons using R502 gas into R22. What can be the effect on temperature and other thing that might affect the efficiency. Thanks.

Dont think Nigeria is banning 22 yet big cheese:mad:

The thing to watch is what oil is in the compressor and flushing the system to prevent acid build up.

But it may be worth considering a different refrigerant that is covered by the kyoto agreement maybe 417a ??

But that would mean complete oil change to synthetic and a very good flush and a good triple vac
