Exergy, exergoenvironmental and exergoeconomic evaluation of a heat pump-integrated wall heating system
چکیده انگلیسی


• Vertical type of ground source heat pump wall heating system working has been studied experimentally.
• Energy and exergy efficiencies of the entire system were found to be 67.36% and 27.40%.
• Average exergy based environmental impact values are determined as average 0.212 mPts/s for all system.
• The change of exergoeconomic factor for all system was calculated as from 74.97% to75.77%.

In this study, a vertical ground source heat pump wall heating system belonging to the Yıldız Renewable Energy House on the Davutpaşa Campus of Yıldız Technical University was experimentally and theoretically studied. The examination included energy, exergy, exergoenvironmental and exergoeconomic analyses from 1 January 2013 to 30 March 2013 (i.e., the “Winter Session”). Data were collected and uploaded to a MySQL database. “The moments when the heat pump is activated” was detected and “Monthly Average Values” were analysed. Theoretical analyses were conducted for the Winter Session and correlated with the experimental results. This study includes exergetically, exergoeconomically, and exergoenvironmental evaluate a building and its heating system from the generation stage to the envelope of the building. The findings are based on applying a low exergy, exergoenvironmental and exergoeconomic analysis to investigate the system performance. The energy and exergy efficiencies of the entire system were 67.36% and 27.40%, respectively, and the energy and exergy efficiencies of the wall heating system panels were 86.61% and 82.90%, respectively. The monthly average exergy-based environmental impact value was 0.212 mPts/s. The exergoeconomic factors changed from 74.97% to 75.77%.
