 PCM integrated glass in glass tube solar collector for low and medium temperature applications: Thermodynamic & techno-economic approachK. Chopra, V.V. Tyagi, A.K. Pandey, Ravi Kumar Sharma and Ahmet Sari Energy, 2020, vol. 198, issue C Abstract: In present work, techno-economic and thermodynamic analysis of an ETC with/without PCM has been undertaken. The results approved that for all selected flow rates, ETC/S obtained higher energy and exergy efficiencies in comparison to the ETC/WS design. The maximum attained value of average daily energy efficiency for ETC/S and ETC/WS was 78.36% and 54.10% respectively with a high flow rate (24 L/h). Also, at this flow rate, ETC/S and ETC/WS attained peak value of average daily exergy efficiency of 23.15% and 20.06% respectively. The average daily energy efficiency of ETC/S was found to be 53.46%, 30.87%, and 44.85% higher in comparison to ETC/WS for low (8 L/h), medium (16 L/h) and high (24 L/h) flow rate respectively. Hence, the integration of SA (stearic acid) as energy storage material with HP-ETC not only stored the thermal energy but also enhanced the system performance.
