Abstract: The development of solar power systems in the tropics is very important as a good alternative energy of conventional fuels (fossil). In addition, the rapid development of batteries become a good new to improve the performance of solar energy storage. Thus, the refrigeration system with a direct current (DC) system is very well developed. This study aims to obtain the optimum performance of the medium temperature refrigerator DC system with solar energy sources using batteries directly without an inverter. With this method, it is expected that the system can be more efficient from energy loss of DC current to AC current conversion. This research is an experimental research which was conducted by built a test rig consisting of two main equipment, namely a DC current refrigerator system and a solar power system. The test was carried out in the Bali- Indonesia region according to the conditions of the intensity of sunlight and the refrigerator system was tested with a load of fresh veget able products. The results of this study found that the DC refrigeration system was able to work well with COP of 3,6. From these results it can be concluded that this system is very feasible to be developed along with the development of electrical energy from solar power. This system is also very feasible to be developed to support the cold chain system in Indonesia to improve the quality of fresh vegetable and fruit distribution. (More)
