    Talking

    Was thinking... Would it be possible to use a can of R134a, a coil of copper line and an empty can of R134a, with fitteing etc, to make a beer can cooler?


    You'd start off with the R134a in the full can, under pressure. Then you'd open the valve and allow the refrigerant to vaporise in the copper tube that is wrapped around the beer can, cooling it very quickly. At the end of the coil is another R134a can which starts empty, and will fill up until both cans are equalized. No refrigerant is released. Then you'd need to 'evacuate' the refrigerant bak to the first can, but hopefully not until you've cooled a few cans...

    I know it' smore trouble than it's worth, but it'd be cool. Question is, would it work?

    who the hell cares! just stick the beer in the ice chest.


    i don't think it would work for long enough to get the beer cold.

    Seems to me may have been easier to just put a refrigerator in the shed. Not as challenging, but easier. Oh and less noise and heat.

    the pressure would equalize in the two cans very quickly. the system would stop working when the full can is probably still 90% full. you might be able to drop the beer temp 5 degrees or so

    Someday I am going to try and tee into the liquid and suction lines of a car air conditioning system. Then run them into an evaporator of an insulated chest inside of the car. Then you would have a cooler running off of your air conditioning system.

    A couple of solenoids here and there for temperature control. I think it would work.

    There's no need for jet engines or freezone.......just an air compressor.

    This sounds like a testing job for us college students
