Conversion of a 50 liter fridge with ammonium -water cycle to Solarpower.

• removal of the electric resistance that originally powered the fridge (very carefully !)
• this receiver is enlarged by winding copper wire around it
• secondary reflector is fixed only for small portion of stray light
• insulation of the fridge with polystyrene (80mm), backside with rockwool
• insulation is covered with offset aluminum
• transformation of a small satelite dish into a Scheffler-Reflector, the fridge needs 80W

 

 

 

It is necessary to work some more on the capacity of retaining the cold. So that during a very warm night or a rainy day the items in the fridge don´t warm up.
