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.
Have them share the heat sink that keeps the ship's power plant from turning itself to slag.

Traveller has magic heat sinks.
I'm beginning to think it's the gravitic manoeuvre drives.

i have been proposing gravitc heat sinks for decades...
Or the Egyptian and Kushite Ice Houses, which go back to Kush being not part of the Egyptian Empire. And work on shadow and pressure to generate ice overnight in the desert.
I've assumed instead a subspace/j-space shunt, but the net effect is the same: heat sinks without radiation. Otherwise, well, everybody fries. But I assume it's part of the PP, not the MD.

Microjumping being a necessity, rather than a shortcut.
(since you provided no context quote, I'm assuming you're responding to my post)
No.
No microjumping involved at all. A PP Cooler system that eventually leads to jump drive... but really has more limited application and doesn't shunt anything particulate, only the thermal energy.
This is a very misleading statement, as there is no magic in Traveller. (please don't take this statement seriously.)
Heat Sinks are a technology that has been discovered, with much testing for safety, and implemented in many fields, but we still don't have an understanding of how it actually works.
Although it might seem like magic to some, many scientists believe that the 'mechanism' at work here is beyond our current scientific understanding of how nature 'works' when it comes to heat sink technology.
It might be more realistic to instead say 'Traveller has psionic heat sinks'. Why? Because we have just as much understanding of how psionics work as we do heat sinks.
Just my Cr0.25 worth of thoughts.

If you can't sit in a swamp, you can always park in an upper atmosphere, though not, I suppose, Mercury.
If you can't explain it, it's magic. That's what makes a magic trick, you know, magic. "How did they do that!?"
Italicized, from what I understand, is due to illusion or misdirection.
Heat Sinks in Traveller work with a process we don't understand that isn't due to illusion or misdirection (as far as we know or can tell). They just work in a way that is beyond Traveller scientific understanding, that we've somehow been able to harness in a way we can use safely, sort of.

Ii refer to them as magic because the just work in the background with no need to account for them, they may as well be embedded unicorn horns. They take up no volume, the cost nothing, and yet get rid of all a ship's waste heat. They have never been described as being part of another system.
