Thermal Solar Powered Refrigerator

By Melanie Loop

After extensively studying the ammonia refrigeration process, the maximum temperature that the boiler was achieving during the refrigeration cycle was thee-hundred fifty degrees Fahrenheit. This is a much higher temperature goal than anticipated in addition to being higher than twice the temperature that is currently achieved by the solar heater. The refrigeration cycle and solar water heaters need a long term study to further research if this is a viable alternative option to alternating current (AC) powered refrigerators. The bicycle running the alternator to charge the back-up battery is a viable form of energy although it needs to be further developed to maximize the efficiency of the conversion.
