Propane Refrigerator Conversion
It seems I can't find suitable information nor parts suppliers regarding the conversion of a normal domestic refrigerator to one that uses Propane.
I have a customer who wants me to convert any given refrigerator (specifically an 18-22 cubic refrigerator) to Propane for campsite use.
I need information on how to do the conversion please.
What cap tube size, suggestions on safety valves, where to get fittings to adapt from the standard propane tank (US-20pound) for use on the refrigerator, etc., and estimated fuel usage per day/week/month.
I don't want to convert the refrigerator to R717 (ammonia) or use any kind of funky adsorbtion system.
How to get the cold control to operate a valve, the fan to work, etc without using anything more than a small square 6 volt battery or two like the kind you use in large flashlights?
The customer can manually defrost the refrigerator.
I supose a small static invertor could be used to drive the lightbulb and fan. But the electrically operated valve for the propane is the question........

That he is, I grew up for a good part in a logging camp and we'd have died laughing if some one suggested wasting such a valuable resource such as propane!
Now you said you have kids? I'm guessing they have bikes? and a car A/C compressor is rather easy to acquire!
lol no, but on a serious note that is what I will suggest, wind or water to spin it, that or do as they have suggested and get a 12volt compressor, a solar cell (They are dirt cheap now days) and over size the condenser and there you go, and teach the kids to use their brains and not open the door all the time and be quick when hey do need to open it. Oh and a deep cycle, that system put togeather well will last many many many years (The one the guy made at camp with a home made inverter and a standerd compressore has lasted till now and from what I hear going, so thats the real viable option you have, that or pelts but that will consume way more then needed)

So basicly you are saying your customer wants to burndown or blowup his cabin? since Propane is very flamable & lays in invisible pools when released to atmusphere.

Expensive but possible: Two sets of Peltier heat modules:
You heat one side of set A by burning Propane or a by-product of oven/stove they produce electricity to run the B set to cool the fridge. Watch temperature limits!
Have seen big boys toys (wine coolers etc) and camping gear using these, in some case they are attached to a refrigerant spider to improve heat transfer. Though the cost to power ratio is high: and they are usually run at 12-15ºC - above safe food storage temperatures.
Also battery, solar, and water wheel compatible, very good for current CO2 global warning concerns;).
