Refrigerator Design Using Solar Energy

Solar energy is one of the most renewable energy sources that has many advantages. Indonesian is a country with many islands and coastal areas, there are a number of remote areas of the archipelago that do not get electricity supply from PT PLN Persero. This study aims to design a solar powered refrigerator as a source of energy. Solar power is chosen as an alternative energy source for this tool, given that sunlight is a resource that can be utilized by coastal communities with no electricity grid. Design this tool is divided into 3 parts, namely: cooling design, Installation of energy sources, connecting to energy sources. This tool has a capacity of 84.6 liters with a total dimension of length 47 cm width 40 cm and height 45 cm. This cooling test was conducted as many as 5 experiments and three replicates for 60 minutes. The results of this study showed that the refrigerator is capable of operating at 8 - 10°C and operating time of 10-12 hours with a capacity of 100 Ah battery. Based on the data obtained, this tool can be used as coolant at remote health centers to maintain the quality of drugs and vaccines.
