Glenn,

I'm starting to wonder if a good ice chest like the Coleman Extreme by
itself
might be sufficient. It can be replenished with ice made in your freezer.

Doug,

You should know me better than that by now. :-) I love my gadgets and
besides, when I have to abandon my shop for the cruising life I will
need things to fix or I will die from withdrawals. :-)

Ah! He's finally 'fessed up. Complexity is the goal. ;-)

#2 is the idea I am leaning towards. I have room to mount an air cooled
BD50 directly below the box with plenty of ventilation.

Couple of things still have me stalled. I would like to use .192" ID
stainless tube which should stand up better to bumps with cans and
corrosion but the thermal conductivity is a lot lower than copper. I
could compensate by going to .335" ID but that might slow down the
refrigerant to much to push the oil through. Think I will stick with
.192" and adjust the expansion valve and compressor speed.

Glenn,

Another alternative could be a large stainless tube or box filled with
PEG/potable antifreeze, and containing the spiral of copper tube
inside. Depends the thermal conductivity of the PEG though. If a
stainless box is used this could have an aluminium finned surface to
improve thermal conductivity.

cheers,
Pete.

I think the really early ones used a big block of ice.
