Cool Bot in COLD climate, anyone??

Hi, folks..

I'm considering buying a Cool Bot and building a small walk-in cooler.  I guess my plan would be to reassemble a repurposed, commercial walk-in cooler.. probably set it up in the back of my barn.

My question is has anyone here used a Cool Bot in a scenario that resembles what I'm describing in a particularly cold climate?  My barn is entirely uninsulated and w/o heat.  I understand that I would have to further insulate any cooler panels that I intended to use.  I guess my concern is whether or not a Cool Bot and/or residential AC unit can function under extremely cold conditions.  I live in Northern Minnesota.  We see temperatures at or around -30 degrees F during winter months.

Is it crazy to think that this would work?  I thought maybe I would build a small, insulated box around the AC unit and leave an incandescent bulb burning inside to keep the AC above freezing..?  I understand I would have to vent it as AC units need to be allowed to vent.

Curious what other folks think.. thanks for your time!

I'm not sure what you are actually asking, if the barn is un-insulated doesn't it get pretty close to outside temperatures in winter? Mine certainly does. What are you trying to do with the cool bot? (in winter) the fridge won't need cooling when ambient temperatures are lower than the desired temperature.

If you want to keep the fridge above freezing over winter you will need a heater not a cooling unit. air to air heat pumps can both cool and heat but they do not work well at very cold temperatures, switching instead to electric heating elements.

In the winter while the temperature is below freezing your insulated box will also go below freezing and your produce would turn into mush. You would pretty much need to get a heater to water it up. Maybe turn on a pump that sends hot water thru a copper coil, or turn on an electric heater.

During summer when the temperature is in the 80F or 90F or 100F. The AC unit in the "window" of your insulated room would have a lower temperature. I don't think it would get below 65F though, but with the by-pass CoolBot electronics you could force an AC unit to bring the temp down to 36F.

So a couple question what size room are you trying to insulate and or what size AC unit do you have, and what is the target temperature of your cool room?
