Abstract

The design and retrofitting of a 200 liters solar powered freezer is a refrigeration system that runs on the solar energy. It was embarked upon as a result of the epileptic power supply to the rural areas in the country and the absence of a grid supply to some locations where needed. The solar refrigerator comprises of the following components, the D.C compressor (Danfoss BD72K), charge controller (30A, 12/24V), solar battery (12V, 200AH), solar panel (12V, 450watt) and a 200 liters freezer. The power is not supplied either from the national grid nor the generator system, but from the solar panel. The solar panels convert the solar energy into electrical energy and store it in the battery. During the day, the solar refrigerator get its power supply directly from the solar panel, but when the solar irradiance drops, the freezer compressor obtain it source from the stored energy (battery). The battery is recharged when excess amount of power is produced by the solar panels. The output supply of the batteries and the solar panel is DC with voltage of about 12-14 VDC. A micro controller was used to display the inner temperature of the freezer and also to protect the compressor by switching it off when the door is opened for a particular period of time. A charge controller was connected to the battery and the solar panel to regulate the voltage from the solar panel for the charging of the battery. The system is capable of running for 26 hours without the presence of sunlight when the battery is fully charged; it also has a high storage capacity of 200 liters and longer operation time as compared to previous solar refrigerators
