Abstract

Indonesia as a tropical country is very suitable for the development of various alternative energies, especially solar power (photovoltaic). This development will be followed by the development of DC motor technology and batteries to replace equipment that uses AC electricity and conventional energy such as fossil energy. This study conducts an experimental research consisting of a refrigerator prototype and a photovoltaic array. Measurements and data acquisition were using data logger system. The refrigerator prototype measurements consist of temperature, pressure, power supply and mass flow rate. For solar power array system, measurement consist of current and voltage output. This study is a preliminary study with the focus on carried out on the calculation and analysis of coefficient of performance (COP) of the refrigerator. The results obtained are the photovoltaic arrays can provide energy continuously during high solar intensity (during the day). The performance of the refrigerator is quite good, with an average COP of 3.2. Furthermore, the future work will be done by further analysis of the solar energy supply. Followed by built a DC refrigerator to be able to compare in depth the performance of both refrigerators system. So that it can contribute to the development of the cooling system technology.
