Résumé

A concentrated solar-geothermal integrated system with a combined ejector-absorption refrigeration cycle is proposed and analyzed thermodynamically for a small community application. A detailed thermodynamic model is established for analysis and performance evaluation. A case of a small community in the Yukon Territory is chosen and the system provides all the necessary demands of electric power, space heating and cooling and domestic hot water at high performance. The overall energetic and exergetic efficiencies are 53.33% and 37.07%, respectively, while the COP en and COP ex of the combined cooling cycle are 1.033 and 0.1131, respectively. In addition, numerous parametric studies are presented to illustrate the effects of several energy sources parameters on the overall performance of the integrated system and the combined cooling cycle. Furthermore, ejector parameters are controlled to get the highest COP en value of 1.164. Lastly, the integrated system is optimized exergetically to reach a value of 55.98%, while the overall energetic efficiency becomes 63.60%.
