Re: Refrigeration-Frigoboat Keel Cooled vs. others?
As long as this old thread has been revived, I'll report that the Isotherm SP flat plate evaporator unit works well. With the small (2cu.') space I built in for refrigeration, the biggest challenge seems to be in getting the stat setting low enough without being off. The placement of the thermostat sensor tube makes a tremendous amount of difference and there is NOTHING in the inadequate manual as to how to position it in a space relative to the evaporator for best efficiency. This could probably still be better.
Anyway, 200 watts of solar panels keeps the beer cold:-) If it's completely overcast for 2-3 days, I'll need run the engine for about 1/2 hour but that's no biggie. With careful use of wattage for things like the SSB and computer charging, this system works but I am very stingy with use of electronic stuff and probably well below the average wattage of most boats.
