Solar Refrigerator

[thastinger]

No offense taken by me beachnut.

If you read my thread you would uinderstand the purpose is to be prepared in the event of no electricity OR fuel for a substantial period of time - such as a solar flare knocking out the grid for months. No power, no propane deliveries. No gas pumping. Not much of anything. But still would like to keep food from spoiling.

The above quote from this thread is the reasoning behind my "blathering" about freeze dried food.

Beachnut - Congratulations on managing to get so much blather in one post and then conclude it with a fairy tale.

Your above statement is exactly why I said this, below, in my "blather" post.

Thanks for starting a great thread, and for sticking with it long enough to get past the "crusty" nay Sayers comments to get some great info out there on solar refer possibilities!
Reading these threads, it kind of amazes me how some people "in the know" so often just want to shut someone down, and seemingly shut them up, rather than be helpful and informative... So glad to see so many others being helpful and constructive, with real life experience!

Some "fairy tales" have a way of actually being true! Sadly, in due time, we will all see.

I will do my best to remember when I write on this forum,,, it is not a friendly place, sorry for my mistake.

Please accept my sincere apology for the non intended offense's, to your forum.

Religious stuff has no place in solar forums.

Glad your thinking, and being prepared for natural disaster. I don't know if we will experience a solar flare, or not, but it is wise to have food, and water, shelter, and protection, on hand regardless. I think everyone should have the ability to be self supportive for a minimum of 3 months! Too many "natural & unatural disasters" happening to not be ready!!!

Have you considered Freeze dried food? No refrigeration needed. Just add water, heat, and eat. I know it is a bit costly, but having a years++,+ supply of freeze dried food on hand that has a shelf life of 25 years, (Mountain house #10 cans), is a great way to go. Also, buying freeze dried food now, at today's prices, may be a real saver due to inflation, when you finally need to eat it as its expiration date draws near. (IF you have not needed it for any emergency). What I buy now, will feed us real well 23 years from now at a probably great savings. For me and my house,, if a year + of food is not enough,, I think I would rather be taken out than have to live through the times that would exist if that were a reality!

Heaven is waiting for me, this I have total faith in, and it will be such a better place than here!!!

If it indeed uses that little it may make sense to run a separate inverter for just that item.

[russ]

Nope. No decimal point missing.

I have a Bosch KSV29VW40.

Found it! They don't offer it in Turkey even.

It is expensive but (Energieverbrauch: 71 kWh/Jahr)

Maybe they don't feel there would be adequate market in many places?

[thastinger]

I didn't know about these but I can't find a 120V 60Hz one.

In Europe we off grid people use a+++ (the more pluses the less energy it draws) fridges. They use less than 7W or 71kWh/year. This is a full size unit.

What is the model number of your frig? I think you lost a decimal point.

It's a technology using compressor and a fan (230v).
I'm happy, it keeps my food and beer cool at almost no energy at all. (My energy readings this summer are quite close to manufacturing promises)

Both Bosch and Siemens make them.
You know about these don't you?
Cos I got a bit worried reading how much energy your fridges draw.

It used about 1.1 for the same period of time when it was used as a freezer. My numbers are probably a bit higher than most because there were 3 people opening the top all the time to retrieve "refreshments"

I used the Johnson Controls A19AAT-2C Freezer Temperature Controller for the conversion. Of course, the freezer is not modified in any way and could still be a freezer if plugged directly into the outlet vs being plugged into the johnson controls unit.

Well, as promised, I'm here to report the results of my conversion. I converted a 5ish year old 8.8CuFt chest freezer to a fridge and my kill-a-watt reported .546Kwh used in a 25 hour period with the temp set at 33F and it got opened alot of times during that period. It works great to keep my beer cold, would be a PITA to use as a normal fridge but I suppose it could be made tolerable with compartmented baskets etc.

Sounds well within the limits of my 24v/200Ah batts, even better if I buy a new, smaller 5cu ft chest freezer to convert. Have the Wh used when it was working as a freezer? oh, and which conversion unit did you use?
Thanks for the info

I've got to try this chest freezer to fridge conversion and I have a kill-a-watt to report the results with. It'll be a few weeks before I do it though, have to many irons in the fire right now.

It's all about insulation and door openings If I were to build one it would have no door shelves just 4 tight fitting slide out drawers so that only a portion of the cold air escaped.
