Thanks for clearing me up!
That ignores that a liquid medium is what facilitates that energy exchange where desired. It takes something to move cooling from the outside of a home, if I may use that instance, to the inside. It is not a gas in gas form. That is inefficient.
Because liquids transfer heat/cooling more efficiently than gases they have to be regarded as Ice Melters on the river.
Take this to the micro climate within the cooler.
A gallon milk jug of ice is progressively melting.
That melt does not go into the cooler where it could cause issues.
It can be drained off as a preferred drinking water. (Because it is cooler it is more likely to be consumed - maintaining fluids that actually help health in the heat) That air space around the jug ice insulates
it somewhat from any liquids outside the jug.
The disadvantage to this is opening the carrier cooler more is bad. So this has to be accomplished by a cooler nazi only when the big guy is scheduled to be exhumed.
However, draining off that water occasionally will extend ice life.
Not more cold right now, but longer cold.
