International Journal of Exergy (IJEX), Vol. 42, No. 4, 2023

Abstract: In this study mathematical model of the organic Rankine cycle driven by multiple evacuated collectors is made in MATLAB 2018a. Results reflect that heat gain 2.726 × 10⁵ W and output temperature 130°C for the collector were highest for collector no.6 at 13:00 hrs. Moreover, the highest system thermal efficiency 14.92%, and exergetic efficiency 56.99% were seen for collector no. 6 at 13:00 hrs. The major exergy loss of 42% was seen in the evaporator continued by the condenser of 32%, expander of 25%, and a minimal 2% in the pump.
