Home made walk in cooler

[Arcade Hunter]

So, I have been thinking about using my outdoor storage shed as a walk in cooler for the early months of deer hunting.   There are some Utube vids out there that show how to convert a digitally controlled window ac unit to do this job.

Personally, as an automation programmer, Im not going to use the setup shown on Utube, I will use a used Unitronics controller off ebay and control the window unit that way..  I would have limitless (almost) flexibility with controlling this as well as being able to change set points for compressor and fan controls without having to take a laptop out everytime I want to change something.  I would also be able to close alarm circuits if the space fell out of any specified temperaturerature parameter.  One more thing I would do differently would be to use a heater element instead of a lightbulb to warm the ac units sensing probe.  I would set it up to sent just enough power to the heater to fake out the unit's sensor without risking overheating the sensor and destroying it.

I will let you know.  This will be a next year project if I really decide to do it but before I fill the shed with crap, I am going to get the walls insulated so I can run a small heater out there in the winter.

Keep us posted how you make out. I am interested in a modified unit,but it is outside of my skill set.
