I don't think the figures Noelex is using in his example are "real world"
Ambient temp inside the boat will be above 25 C unless its in winter. Fridge temp wanted will be much lower than 7.5 C. Fridge temp should be 4 C or below.
Currently my ambient temp is about 32 C when the hatches are open and 34 C when I am off the boat. It's set about 3 C so the beer
is COLD. But when I put beer
in the fridge its at ambient temp of 32 C.
So not only does the compressor
work hard for the ambient air temp drop it also has to cool down water
that's bloody hot to begin with!
And when do we dink more cool water? On hot days, of course. So if our water consumption
on hot tropical days is 4 x 500 mil drinks, and there's two people on board that's 4 kilograms of water to be cool 30 C per day.
My Dometic does work very very well... Small box size and good compressor
and nice digital temp gauge... So I tend to use it a lot, especially when I forget to put in the beer or need to cool something quickly...
In conclusion, take published electricity consumption
figures and double them! Then multiply by 6!!!
But when we are talking about ice cold beer the electricity consumed really takes second place
