چکیده مقاله

This paper presents the numerical modeling-based optimization of the indirect–expansion solar-based (IX-SHP) water heating system to supply hot water for use in maritime ships.the verification of the proposed IX-SHP system, the system performance is investigated for use in a 50-person maritime ship in the conditions of the Persian Gulf. The coefficient of performance (COP) and the collector efficiency (CE) are considered as two indexes for the system performance. The optimization process is carried out via the single-objective and bi-objective Ant Colony Optimization (ACO) algorithm to maximize the system performance., to achieve the optimum configuration of the system, TOPSIS decision-making method is integrated with the ACO algorithm by programming under the MatLab environment. The optimization results demonstrate that while the CE of the maximized IX-SHP decreases from 61% to 46.5%, its COP increases greatly from 2.5 to 6.9. Accordingly, the total working hour decreases by around 281 hours in contrast to the initial system. , the overall power use of the maximized system is largely reduced., the bi-objective optimization offers a more effective and efficient system compared to the single-objective optimization., the environmental analysis demonstrates that employing the optimized IX-SHP in a 50-person ship prevented the consumption of 7510 cubic meters of natural gas per year and also prevented the release of 21 tons of carbon dioxide per year into the environment. , the annual external cost decreases by about 2580 USD. Moreover, 34 m2 photovoltaic-thermal panels are needed to produce 80 kWh per day for a 50-person maritime ship.
