At large scale (think like walk-in coolers of supermarkets), this is actually being done in the form of district cooling [1].

The problem is that the piping itself and the circulation required are sources of energy loss, and it's hard enough to keep these appliances sealed so they don't leak their coolant - most coolants have insane CO2 equivalent potentials. It's not worth the effort.
