Little early to be thinking about it, but other conversations got me revisiting an old idea I've been kicking around for a few years.
Now before I tell you about this you have to at least think about it some before you start laughing at me.
The big drawback is of course the electricity consumed running AC. Lets face it a lot of shops just are not insulated well enough to even bother. The second drawback is maintenance. It's not easy keeping the sawdust out of a window unit.
So whats it cost to run a small chest freezer?
How about a circulation pump? The pumps cheap. the one on my outdoor boiler runs 24/7.
So take an old freezer, fill it with old antifreeze
put a circulation pump on it and cycle it through a heat exchanger like my boiler uses and blow air across it. Box the exchanger and the fan in, use some good filtration to keep the dust out. I've been kicking this idea around for a while now. I have a freezer, in fact it has food in it right now. In a few weeks I'm getting half a hog from my brother and I'm going to plug the new one in and move everything to it.
All I really need is antifreeze and I can get that from the junk yard for 50cents a gallon for used stuff. I may have to add a few gallons of new to boost it a bit.
Worst case scenario is it doesn't work. All I'll be out is $30 or $40 in antifreeze and a used freezer thats probably only worth $25 or so and a few bucks in fittings
