Exergy analysis of a developed flat-plate wickless-heat-pipes solar-collector with series condensers
Keywords:solar thermal-collector, heat pipes, exergy analysis
A flat-plate wickless-heat-pipes solar-thermal collector with series condenser-coolers (FHSC-S) is developed. Indoor solar experiments are conducted to investigate the thermal behaviour of the FHSC-S collector. The collector is tested under different experimental parameters (collector tilt angles, water flow-rates, solar irradiance levels, and inlet-water temperatures). This part (I) presents the collector design and details, besides an exergy analysis. The experimental results showed that the collector performed well. The inlet fluid exergy, outflow exergy, and gained exergy are increased with the increment in the inlet temperature. The maximum and average values of the collector’s exergy efficiency are 0.20 and 0.08, respectively.
