Experimental Performance Evaluation of a PV-Powered Refrigeration System

WOS: 000296754700002O. Ekren, A. Yilanci, E. Cetin, H. K. Ozturk. Experimental Performance Evaluation of a PV-Powered Refrigeration System // Electronics and Electrical Engineering. - Kaunas: Technologija, 2011. - No. 8(114). - P. 7-10. This paper presents cool-down, and steady state performance of a 76 W direct current operated household refrigerator powered by a photovoltaic (PV) solar panel and a battery bank. Exergy method has been conducted to investigate of the performance of the PV powered household refrigerator. Experiments are conducted with different cooling loads. In use of this type system, it can be said that over-loaded condition in the refrigerator should be avoided. From the obtained results, it is seen that exergy efficiency of the system is very low due to the low energy conversion and exergy efficiencies of the PVs. This situation is also seen from exergy destruction values. For all cases, exergy is destroyed highly in the PVs.
