Thermodynamic analysis of multiple evacuated collector-driven organic Rankine cycle

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.
