ABSTRACT

A novel hybrid combination of the copper–chlorine (Cu–Cl) thermochemical cycle and the Goswami cycle is planned for electrical, cooling, and hydrogen production. In this cycle, geothermal (renewable energy) and natural gas (nonrenewable energy) are used to provide the energy requirements of this multigeneration system. The natural gas in this cycle is used to comply the requirement of the temperature limit for the reaction of the Cu–Cl cycle. This miultigernration system is investigated versus energy, exergy, and exergoenvironmental aspects. The results of this analysis represent this proposed system produces 259.2 tons of hydrogen, 7.82 MWh of electrical energy, and 13.1 MWh of cooling energy over the year. The exergy efficiency for the Cuexergy efficiencyCl, Goswami cycle, and the whole cycle is obtained as 75.8%, 28.7%, and 13.9%, respectively. Moreover, the exergoenvironmental analysis reveals this factor for the Cu–Cl and Goswami cycles is calculated as 0.61 and 1.24, respectively, and for the whole system is equal to 0.68.

摘要

铜-氯 (Cu-Cl) 热化学循环和 Goswami 循环的新型混合组合计划用于电力、冷却和氢气生产。在这个循环中，地热（可再生能源）和天然气（不可再生能源）被用来满足这个多代系统的能源需求。该循环中的天然气用于满足Cu-Cl循环反应的温度限制要求。与能量、火用和外部环境方面相比，研究了这种多功能系统。该分析的结果表明，该提议的系统全年可产生 259.2 吨氢气、7.82 MWh 电能和 13.1 MWh 冷却能量。Cuexergy 效率Cl、Goswami 循环和整个循环的火用效率分别为75.8%、28.7% 和13.9%。
