Ammonia versus Compressor Fridge...
After all the talk about Danfoss compressor fridges and how much better they were than the old school Ammonia Units, I decided to 'fiddle with mine and do a long term test using a remote digital recor...

I have a 4 cuft Novakool with a Danfoss compressor. It certainly has it limitations. I opened up the ventilation areas and installed two computer fans which I manually activate in hot weather. My NovaKool works great in moderate to cool temperatures. When the ambient temps increase to the upper 80s, the compressor runs almost continuously. It pulls a bit over 3 amps and can use about 75 AH/day. The downside is on hot days I need to get into the sun for many hours to feed the solar system. On cloudy days or when camped in the woods I can only got two days before my 300 AH batteries are half depleted. If I need to run the generator, it takes forever to regain the charge. In theory my built in charger puts out 40 amps so I should be recharged in about 4 hours. That does not happen. It seems that the charging rate slows quickly and it takes probably closer to 6 hours to recharge. Whenever I am in this situation, I wish I had a refrigerator that ran on propane.
