Abstract
The substantial dependence on fossil fuels as an energy source has resulted in considerable ramifications for both society and the environment, manifesting in problems such as air pollution and exacerbating the issue of global warming. In an effort to tackle these challenges, the objective of this study is to alleviate these issues through the utilization of renewable energy sources. This study proposes the implementation of a new multigeneration system that can deliver a range of vital useful outputs to the residential buildings, encompassing electricity, cooling, hot water, heat and hydrogen. The present system, in this regard, uniquely combines a sonohydrogen production process with other subsystems. This developed system is then evaluated based on energy and exergy efficiencies, alongside an evaluation of its environmental effects. The results of this study reveal that the energetic efficiencies for the steam Rankine cycle (SRC), organic Rankine cycle (ORC), and Brayton cycle (BC) are 35.99 %, 14.56 %, and 32.04 %, respectively. Additionally, the exergetic efficiencies for the SRC, ORC, and BC are 74.30 %, 43.79 %, and 63.11 %, respectively. Furthermore, the absorption system demonstrates energetic and exergetic coefficient of performance (COPs) of 1.65 and 0.63, respectively. Moreover, the findings from the environmental analysis specify that the system has the potential to prevent the discharge of 2.513 kg/kWh of carbon dioxide into the environment.
