Abstract A solar refrigerator operates almost exactly the same as the one you have in your kitchen now, with the exception that is powered by both solar and conventional electricity. They are powered by solar photovoltaic arrays (solar panels) and DC or AC/DC power as a back up energy source. Made from environmentally friendly (non-CFC) materials, solar refrigerators are designed to last a lifetime, and should never need to be replaced. Generally the refrigerators are insulated with high efficiency polyurethane foam insulation to ensure low energy consumption. Depending on your climate, you may want to purchase a dual compressor model of solar refrigerator. These compressors are really only necessary if and when the refrigerator is used heavily in hot weather. The compressor can be either remote or free standing, depending on whether you would like to flush mount your fridge in with your cabinetry or if you'd rather mount the compressor on the bottom or the refrigerator.

SOLAR REFRIGERATOR
SOLAR REFRIGERATION.pptx (Size: 2.94 MB / Downloads: 46) INTRO Solar powered refrigerators are most commonly used in 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. IN BRIEF Refrigeration may be defined as the process of removing heat from a body or enclosed space so that its temperature is first lowered and then maintained at a level below the temperature of surroundings. The system maintained at the lower temperature is known as refrigerated system while equipment used to maintain this lower temperature is known as refrigerating equipment. The unit of refrigeration is ton of refrigeration or simply ton denoted by TR. One ton of refrigeration means amount of heat required to remove from one short ton of water at 00C to produce ice at 00C at 24 hours. REFRIGERATION CYCLE The refrigerator in our kitchen uses a cycle that is similar to the one described in the previous section. But in our refrigerators, the cycle is continuous. In the following example, we will assume that the refrigerant being used is pure ammonia, which boils at -27 degrees F. This is what happens to keep the refrigerator cool. The compressor compresses the ammonia gas. The compressed gas heats up as it is pressurized. The coils on the back of the refrigerator let the hot ammonia gas dissipate its heat. The ammonia gas condenses into ammonia liquid (dark blue) at high pressure. ADVANTAGES Environment Friendly:Solar energy is available freely , abundantly and is a clean source of energy. Solar refrigerator runs on solar energy ,thereby saving lots of electrical power which would have produced by conventional power plants causing lots of pollution. Longevity: Operates continuously for years as proven by prototype units tested at various locations around the world. Scalable: Suits applications in a wide range of sizes, from portable 50-liter coolers to building size air-cooling systems. Applications Comfort air conditioning of auditoriums, hospitals, residents, offices, hotels etc. Manufacturing and preservation of medicine. Storage and transportation of food stuffs such as dairy products, fruits, vegetables, meat, fish etc. Manufacturing of ice. Treatment of air for blast furnace. Production of Rocket fuel. Computer functioning.
