Now a day's refrigerators are very essential parts of human life and cannot sustain our life without these. But these became more commercial so that simple solar power refrigerators working on evaporative cooling principle are essential. These Solar-powered refrigerators are able to keep perishable goods such as medicines; meat and dairy cool in hot climates, and are used to keep much needed vaccines at their appropriate temperature to avoid spoilage with less cost. This paper presents the design and fabrication of solar power refrigerators by using different materials. Finally, heat transfer coefficients have been calculated for different models making with different materials in order to get better cooling effect within a less time period.
