Fred, By installing an alluvial fan, you will drop the precipitation loss between the freezer and the frig by the difference in the temperature fleeb. This may not sound like much of a savings, but over the period of 12 hours your fleeb to current ratio will be substantial. Hope this helps...T -----Original Message----- From: Fred Hazzard Sent: Monday, February 18, 2013 10:51 AM To: w...@wbryant.com ; cnc-list@cnc-list.com Subject: Re: Stus-List refrigeration - icemaker? Wally: Please write a little more about what I could gain by having a fan. I have a thermostatically controlled set of louvered doors between the refer and freezer. The refer stays cold and freezer works. Do you think I would gain some efficiencies by adding a fan. I wired for a muffin fan but did not install one. While cruising in the summer in the NW I use about 50 to 60 AH per day.

My 2 cents: The insulation is more important than the compressor system, if you're looking for energy efficiency. I have the Frigoboat system, and absolutely love it, but also believe that the Isotherm system operates under the same principle and doesn't have the external sintered bronze plate. While I probably have a ridiculously expensive fridge/freezer system (the vacuum panels) it also works fine in Mexico in the summer when the tropical sun is hot enough to literally (I did it) fry an egg on deck. It probably draws 40Ah on the worst day, but normally only pulls about 25, keeping the freezer at 10F. I honestly think that the circulation fans <http://www.wbryant.com/StellaBoat/Projects/galley/pipefan/> have a huge impact on power consumption. Last summer I was defrosting the freezer and the fan went from 10F to 110F with 80 percent humidity. It wasn't the first time, but it was the last. <G> I didn't carry a spare fan (you can't have a spare *everything*) so lived without it for two months. I was amazed at the difference in system behavior and power consumption on the freezer side. If building a system, I would definitely consider internal fans a valued component. And even if not believing it, I'd run the wire through the insulation while adding other components like copper tubes, and just seal the wire off with some Ancor heat shrink so the fans could be added later if desired.
