EXERGY ANALYSIS OF A SINGLE-ENDED GLASS DIRECT FLOW EVACUATED TUBE SOLAR COLLECTOR

Exergy analysis for a single ended glass evacuated tube solar collector system was carried out in this investigation. The second law of thermodynamics was used to obtain the net exergy, exergy destructed, and exergetic efficiency of the Evacuated Tube Solar Collector (ETSC) system. According to the mean solar insolation in Jordan and assumptions of calculation in specific region around the year, the results obtained show an exegetic efficiency of 65.88 % which seems to have a steady value despite the increase in the temperature difference of water in and out of the collector.
