RE: What About Thermoelectric
I have no experience with thermoelectric refrigeration. Power boaters using them in cool climates like them. They only reduce the temperature by 40¢ª F. and their energy consumption is high. I did buy one of the small units for a car and put it on the test stand That I use to evaluate 12 volt refrigeration systems. The first test after 24 hours with an empty box it consumed 72 amp-hrs. Ambient temperature was maintained at 79¢ª. The second day two warm cans of drink were placed in the box and the temperature data logger indicated it took 8 hours to cool the drinks to 45¢ª. I believe the units could be useful if cold products were placed in the box to start with along with ice. By turning the unit on when extra battery capacity is available it will extend the life of the ice.
