I found this link:

https://www.storeitcold.com/standing-guide/

And it has peaked my interest. Has anyone had any luck with this type (window AC unit) setup?

Interesting note on another of their pages:

A concrete block has a ~.2 R value per inch (so ~.8 R value per 4” block). If your average underground temperature is 52-62°F (11-16°C) and you want to be within that range (for a wine cellar for example), then you don’t need insulation. If you want to be lower than that though, you will need some sort of insulation, otherwise, you’ll be spilling out all the “cold” through the walls and into the ground.

Fiberglass Batt
DO NOT USE FIBERGLASS BATT INSULATION! Regardless of whether or not you have a vapor barrier, moisture seeps into the fiberglass insulation. This moisture creates a moldy nightmare and also decreases your insulation value. The decreased insulation value results in higher electricity bills; your A/C now has to work constantly to cool the cooler, since the cold air is leaking out through the now uninsulated walls. Please do not use this!

Done that... Cleared out the space, insulated with 4" pink Styrofoam, covered with FRP panels. I use a STC1000+ to control the AC unit. 280 cu ft of cold storage/conditioning space.
