Even on TL 4 or TL 3 or even lower worlds there will be plenty of solutions shipped in from off world, that can be operated at lowers TLs.
The Icy Ball refrigerator for example, as long as they can build a fire they can make ice.

They used ice, but by 1870 commercial ice manufacturing was available. So they could make ice where it could not be practically shipped in.

TL4 to me so very doable. Between that and likely hold environment, ice loading can be stretched.
Before that of course there was salting and/or drying, so earlier TL than 4.
IIRC there was a TL desirability factored into speculation. Part of that for food could be assumed as increasing quality of preservation.
See that refrigerators are in fact heat pumps, they do not create cold, but remove heat (cold does not exist physically, and cannot be created).
While the practical effect may seem similar, they need another matter where to transfer the heat, a commodity they would not have in space (or in any vaccum environ, for what's worth)

Quite true. External hull mounted containers would have to have huge radiators or some other magic heat sink, or connect to the ship’s life support/climate system.
Another point is that reefer type handling requires heating as much as cooling.
