Bruce,
No, it is cold storage capacity by volume, as Jon alluded to (HOS) and there
have been several very successful solutions developed recently for the
transport of human organs from donor to recipient, which work much better
than the conventional fluids like brine and ethylene glycol. These mediums
require the -40 temperature to freeze.

That is really good info....... thank you. I think you are correct about
keeping the systems separate. Combining them will create far too much
complexity. I have made the same observation of cold plate performance
that
you have, but I think that is because of the use of brine as the storage
medium for a freezer applications. Its state change is far too warm to be
efficient. There are far better solutions for cold storage capacity,
hence,
the -40 degree requirement.

I have the idea that I heard somewhere that the preferred liquid for the
cold plates was a mixture of ethylene glycol rather then "brine". I
believe that the reason is that by mixing water and E.G. you can control
the freezing point which is pretty much what you are trying to do.
