PTO-Driven Beer Fridge

[groundcover]

Combination urinal / coffee maker would be just the ticket for those those early morning calls !

Recover the heat of the urine and use it to make the Beer Cold! Talk about a vicous cycle! And hope the guy that welded the heat exchanger can weld better than me.

Refridgerant compressor could be run off the mid-pto output stub shaft. I'm thinkin' one off of a car or truck. Evaporator plus suds in a weight box. Even beersicles would be possible.

BTW: You really only rent beer.

Beer & ice cream. Mmmmm ...

Oh, wait!

I should'a posted that on the Red Neck thread. .. as a blue-collar White Russian.

"Bear" with me - a short story. Many, many years ago. A very sharp mechanical engineer working at a local company. Manufactured a small "unit" that fit on the end of an air compressor hose. This unit "split the air" into hot air and cold air. The nozzle from the "hot air" side would boil water. The nozzle from the "cold air" side would freeze water. It didn't happen as quick as your stove or freezer but it DID work. AND both would work at the same time.

The metal nozzles( hot side - cold side) ran thru small containers of water. We all thought he was "full of it". However - about three hours later - ice was forming on the cold side - the water was boiling on the hot side. He just laughed and never explained how this worked. To this day, I still wonder about this.

Has anybody ever seen or heard of this..........

I've installed a few in electrical/electronic enclosures in hazardous atmospheres.
Standard Vortex Coolers | Enclosure Coolers
Vortex Tube, Model 16, 28, 38, 328 Vortex Tubes use compressed air for spot cooling, vortex tube, vortex tubes, cooling with compressed air, ITW vortec, cool without refrigerants, cooling without refrigerants Ranque-Hilsch tube, Maxwell's demon
It would take it quite awhile to col the beer good and takes quite abit of air.

Hmmm........ so this fellow had simply duplicated a unit from an existing patent. For sure - it took a WHOLE LOT of air. The local plant had massive air compressors. He did this "thing" just to impress the rest of us. It used too much of the available compressed air and was never used for any purpose.

We made our copies of the vortex cooler in the bench department mid-'90s. They were indeed air hogs, but in a factory complex ...

Shirts were taking our coolants, tapping lubes, and lead hammers for new OSHA regs/stds.

We hoped to use the air coolers in lieu of flood or mist coolant on the mills, etc, and just got the orifice right when we were told not to copy patented stuff.

We kept out Anchor Lube, .. and hid Tap-Magic in our roll-aways.

They gave us some vegetable oil stuff in trigger-spray bottles. It worked ok but smoking it on a heavy cut didn't smell like dinner cooking.
I keep my lager on the floor for consistent temperature. No PTO power needed, and no bumpy ride. :drink:

It might be theoretically possible... Canadians introduced me to burning propane to power refrigerators, up in the bush. I'll have to dust off my old thermodynamics textbook. I remember the Carnot Cycle and the Diesel Cycle but not the Vicious Cycle.

I will do almost anything to find an alternative to having to use the PTO on my tractor if I can. I keep my bush hog on it all the time, and it's pure torture putting it back on after I take it off. Probably the thing that I hate doing more then anything else.

For electricity, spending a grand on a Honda generator was a no brainer. Might even be one of my smarter purchases!!!

I put gauge wheels on the front of my cutter, they stick out maybe a quarter inch lower than the skids. I put them on to help it ride more smoothly. But a side benefit is that the mower now rolls and on the concrete floor of my barn it rolls quite easily. If I grab it by the rear wheel I can easily move it by myself and steer it by pushing the rear wheel sideways. To hook it up I drive the tractor into the barn and then push the mower into place, easy-peasey.
