I hate peltier systems, I had a wine cooler that used that system damn wine was hotter than outside of the cooler. I like the system in the refridgerator in the RV, it uses heat either from heating elements or propane to heat an ammonia solution seems like a very effective solution. If I could use the heat from the roof to heat the ammonia that would be a bonus. But I really don't see an easy way to do it. For now I will just install the 300watt's of solar panels and keep them as cool as I can, hopefully the white knight flex-roof will help with cooling and I always leave a good 2 inches under solar panel just for some ventalation. I have some panels on my changehouse/washroom for the pool at home that powers the lights in both rooms and they can get pretty damn hot on a sunny day. SNO
The wine cooler wasn't set to heating was it? Or reverse connected?
And I wrote about this recently - somewhere - but I finally understood why people spent >$1.000 for mobile compressor fridges. In my case, an Engel 40L (and NOT its "W" competitor).
I started with a $145 ~35L Peltier. Though excellent as an esky (unpowered; ice would last 3x longer), it would draw 6-8A and that would only cool to "20C below ambient". I already had ~100W or solar but would need another ~100W which was ~$750 at the time, plus another battery. And all that for a mere 20C cooling for 24 hours assuming sunny days.
Hence my $900 (RRP $1300) Engel 45MT (or whatever) with its max 2.5A draw that would cool to -19C in +45C heat. In practice she draws ~1.25A and for FAR less duration than my Peltier.
My old 38AH AGM battery had no problem powering her for 24 hours.
I once wanted an absorption type aka 3-way cooler thinking that gas was the way to go (before the greenhouse effect became formal LOL). But 3 things have since occurred: LEDs & flouros have replaced gas lighting; solar is economical & viable; and I want cooling whilst mobile. And when it comes to using electricity, the absorptions are shockers. Plus they don't have freezing capabilities of the compressor types.
I had considered modifying the absorption's heater to be solar fired (parabolic mirror etc), but no, the Engel etc wins hands down.
So now I have a 40L compressor fridge which I can use to create ice or chill "Techni Ice" packs that I transfer to a 60L "super" esky where ice lasts 3 days in 40C heat.
Without solar, I merely have to run my engine for maybe 5-10 minutes to charge the fridge battery for another day or 2.
Small update: Made a battery box area for the solar batteries in the bottom of the closet (was very deep, too deep) It will hold 2 deep cycle 120AH. Still need to add a vent on the outside of RV for batteries.
And the computer cabinet is using the same closet but the upper portion Jetway nf9 w/ i3-3.2ghz, 4gig, seagate 500gig hybrid, HD, XM, Phidget 1018, TPMS, front and rear Parking Distance, usb 5.1, 12 onboard usb, 6 port ram hub.
Computer running Driveline (of course)
More to come just finishing off some things. SNO
Very clean install! Your whole project is coming out nice, keep up the great work!
I am also using a variation board, Jetway NF9G. Same board but socket G2 for mobile processors. In fact most of my next install is the virtually identical to yours, including Driveline! :D
