Design and Analysis of a Novel Renewable Multi-Generation System through Energetic and Exergetic Investigation

There are many studies and research conducted on the multi-generation systems, however there is still a gap for some contributions. By reviewing the literature in the renewable source of energy it is explicit that many researchers performed number of studies about the design and analysis of multi-generation systems. However, none of them have chosen n-pentane for fluid running in an Organic Rankine Cycle (ORC), neither the thermal assessment of the multi-generation system have been studied. The primary goal of this research is to layout a novel multi-generation utility based on geothermal energy driven ORC, which is used to generate domestic electricity, heating, cooling and drying. Generated electricity can be partially used for domestic needs while the rest is proposed to utilize the hydrogen generated by electrolyte. The heat recovery of the ORC cycle drive a single effect absorption chiller (SEAC) for producing heating, cooling and dry air. Thereby, it is aimed to demonstrate an efficient process with improved energetic and exergetic efficiency. In this study the mass flow rate of the geothermal is 11.88 kg/s and the origin temperature is 483.2 K while utility energetic and exergetic efficiencies are 1.537 and 0.4121 respectively.
