The Design and Fabrication of Solar Powered Mobile Cold Room is a refrigeration system that uses 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 mobile cold comprises of the following components, the D.C compressor (Danfoss BD92K), charge controller (40A, 12V), solar battery (12V, 200AH), solar panel (12V, 600watt) and a 500litres compartment. The power is not supplied either from the national grid nor the generator system, but from the solar panel. The solar mobile cold room comprises of the solar panel that collects the solar energy. The solar panels convert the solar energy into electrical energy and stored it in the battery. During the normal running of the cold room, the power is supplied directly by the solar panel, but when the output power of solar panels is less, the additional power is supplied by the 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 12V. A microcontroller 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 period of 60seconds. The charge controller is connected to the battery and solar panel to regulate the voltage from the solar panel for the charging of the battery, the supply from the battery is used in running the D.C compressor of the cold room in the absence of sunlight or when the sun intensity is low. The system is capable of running for 18 hours without the presence of sunlight when the battery is fully charged; it also has a high storage capacity of 500litres and longer operation time as compared to previous solar refrigerators.
