I work on these containers that contain food. Would be pretty easy to set one up with air conditioning, there’s even a vent to let in outside air for the chill box (refrigerator) setting. I’ve turned a couple of them into air conditioned spaces to hide out in at work. Ahem, “store our climate sensitive orings and gaskets” (play cards on breaks without bosses finding us). I don’t work for a shipping company I just have some of these as assets when walk in freezers and such go down.
