Water cooling comes to mind ... but do you want a moisture laden

Perhaps you need to think along the lines of how people in hot countries
use pottery jugs etc to keep liquids cool. The slow seepage of liquid
through the material cools the jug via evaporation.

Yes - and I use that method a lot when under canvas, have done for 60 years.

But it's not the same thing as coolking a larder in a building.

In most Victorian pantries it's exactly the same thing, no DPC so the
pantry is cooled by water evaporating from the porous brick.
