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.

Solar powered refrigerator
Solar-powered refrigerators are most commonly used in the developing world to help mitigate poverty and climate change. By harnessing solar energy, these refrigerators are able to keep perishable goods such as meat and dairy cool in hot climates, and are used to keep much needed vaccines at their appropriate temperature to avoid spoilage. The portable devices can be constructed with simple components and are perfect for areas of the developing world where electricity is unreliable or non-existent.  Other solar-powered refrigerators were already being employed in areas of Africa which vary in size and technology, as well as their impacts on the environment. The biggest design challenge is the intermittency of sunshine (only several hours per day) and the unreliability (sometimes cloudy for days). Either batteries (electric refrigerators) or phase-change material is added to provide constant refrigeration.
complete constructional and working details of solar refrigeration
tell me more abt "SOLAR POWERED REFRIGERATOR"
sir I have to deliver a seminars on Solar powered refrigerator at college . so please send me seminars presentation as quick as possible.
please send me seminars presentation
plz send this full report to my mailid kakijoja[at]gmail.com
can you pls send me the full project report about solar water cooler by thermoelectric cooling
i want ieee papers of this project
because iam doing my project on this
