The refrigerant inside of a refrigeration system is in its own "artificial" closed atmosphere maintained by a compressor. So altitude would have no effect.
The surrounding temperature would effect the performance of the system but I've never heard of the altitude effecting the system.

Critical temperature means liquefy the gaseous up-to 374 degree centigrade. No mater if water goes beyond 374 will not affect to convert liquefy gas.

By varying the pressure the freezing point can also be changed. So in case of different altitudes the same refrigerating could be possible. For example water is used as a refrigerant in var system.

Because refrigerating effect depend on the critical temperature of substance such as freezing point.
Water critical temperature = 375.16k.
Water critical temperature = 375.16k.
