Has anyone tried to convert a propane or three way RV fridge to straight solar?
These fridges do not have a compressor but rely instead on burning propane to create heat for vaporization or electric heaters when plugged into the grid or a battery. The core portion could be heated by concentrated sunlight to heat the refrigerant to the vaporization point. Many area s with abundant sunlight also happen to be in desert area with cool nights. Given adequate insulation these fridges could keep the interior cool overnight and provide cooling during the warmer daytime when refrigeration is needed.
He uses solar to boil ammonia from ammonia water during the day, to separate out and store up liquid ammonia, then at night he releases the liquid ammonia to perform the refrigeration part by the ammonia turning to gas. Then he runs the gaseous ammonia through water to recover it/absorb it (forming ammonia water) and store it, then the cycle repeats the next day.
Hey Arkyvee I know what you mean because I have the same problem on my Ubuntu machine. Welcome to windoze oriented programming. I complained to web management two months ago about this nonsense but evidently to no avail.
Real energy conscious people already know Ubuntu runs less energy compared to wondoze because of fewer computation cycles needed for same task but evvidently this is not a priority for a website directed to off grid and energy conserving people.
As for the patented cycle. He is only able to patent the specific cycle.
Regarding modulating the heat on a solar driven device. Try shading with blinkers. As long as the reflected or focussed sun rays can exceed the temp needed to boil the ammonia it should work. Practicality suggest this system is best used to freeze blocks or bottles of ice that in turn is used for retaining cold in an ice chest like arrangement if you store food in there.
