Solar refrigerator from freezer pdf

[Laurie T]

Greetings,

After our discussion on changing out my ice box to a refrigerator, I read this how to article with keen interest on how to convert a freezer into a solar refrigerator that takes less than 100 watts a day.

Here is the link... http://www.builditsolar.com/Projects/Conse...hest_fridge.pdf

He is converting what looks like a home freezer and I've be interested to know if anyone has ideas for adapting this to a rv or marine size freezer.

Thanx!

It seem to me that his main point is that because the door is horizontal instead of vertical, you don't loose so much cold every time you open the door. I don't know if there are any chest type freezers that might be small enough to pull this off. Also the author what must be a robust solar/battery setup already in place - he's just trying a way to stretch that setup.

All that said it seems SO obvious. If our kitchens weren't designed for verticle fridges this would be the way to go . . .

If you are up to it, join the scampers group on yahoo. kamperbob did a swap out to a 12 dc compressor. While at our last meeting he was quite pleased with its performance, He is more then willing to share his info.

Hey thanks, I didn't know there was a scampers groups and I love learning from all the tiny trailer forums.

Warmly,

Hmmmm... Does look like a good idea though. Will give it a try with something more like THIS.



Might even work better than claimed. Who's to say until one of us tries it. Will keep everyone posted!

Later!

Those in the world of off the grid living have had a few discussions on this writeup. Most with more knowledge than I can ever dream of having feel it's hogwash and they have good science explanations why. But none of them have tested this concept either.

The big key may be insulation. Freezers have much more insulation than fridges. Their compressors and refridgeration units are identical to fridges I think.

Unfortunately there has been no reports of continued succes, failure, updates or anything about this guys unit since that was put on the web a good year or more ago. Least not since I checked last.

I did see a solar-powered ammonium hydride 'fridge at a renewables show on Earthday in the San Francisco area once. It was a converted RV fridge with a small satellite dish that had been converted into a parabolic reflector directing sunlight at an array of mirrors that directed the sun's heat down to the heating element of a small RV fridge.
