Solar Powered Refrigerator

The quantum of energy in the universe is constant. Neither can man create energy nor can he destroy it. All that he can do is to discover new source of energy that the natural has provided and make it usable for his needs by new and more efficient ways of conversion.
A solar powered refrigerator using an intermittent ammonia-water absorption system as refrigeration in remote areas where electrical energy is not available is described in this paper.

In my present paper I have made an analysis of feasibility of utilization of solar energy in the Indian climatic condition to produce ice. An intermittent-ammonia-water cycle was found to be normally used for this purpose.

Solar energy is collected in flat plate collector and only two components are used for this refrigerator. One component as generator and absorber and other as condenser and evaporator Regeneration takes place during the day time and refrigeration at night. Ammonia is used as refrigerant..
