摘要

本研究提出了一种利用天然气来满足阿巴斯港一座住宅建筑的电力、淡水和冷却需求的系统。该系统包括燃气轮机、吸收式制冷机和多效海水淡化(MED)装置。燃气轮机产生的能量用于发电，多余的能量用于生产冷却和淡水。最后，对系统进行了努力经济评价。研究了环境温度对输出功率和火用电流的影响。对吸收循环的COP进行了研究，结果表明，在150°C的工作温度下，效率比在90°C的工作温度下提高到20%。最高的耗热经济成本率与吸收式制冷机有关，最低的与热回收蒸汽发电有关。结果表明，环境温度升高，生产能力降低。增加燃油流量增加功率。对降低环境温度和增加燃料流量两种不同解决方案的评估表明，考虑到吸收式冷水机组的火用成本比燃气轮机高10倍，增加燃料流量是一种更好的解决方案。

Exergoeconomic Analysis of the Cycle of Cogeneration of Power, Cooling and Freshwater for a Residential Complex in Iran

This research presents a system to use natural gas to meet electricity, freshwater and cooling needs for a residential building in Bandar Abbas. The system includes a gas turbine, absorption chiller and multi-effect desalination (MED) plant. The energy produced in the gas turbine is used to generate electricity, and the excess energy is used to produce cooling and freshwater. Finally, an exergoeconomic evaluation of the system is performed. The effects of ambient temperature on the output power as well as the exergy current have been investigated. The COP of the absorption cycle has been investigated, and the results show that at an operating temperature of 150∘C compared to 90∘C, the efficiency rate increases to 20%. The highest exergoeconomic cost rate is related to absorption chiller, and the lowest is related to heat recovery steam generation. The results show that if the ambient temperature increases, the production capacity decreases. Increasing the fuel flow rate increases the power. Evaluation of two different solutions to reduce the ambient temperature and increase the fuel flow shows that increasing the fuel flow is a better solution, considering the exergy cost of the absorption chiller, which is 10 times higher than that of the gas turbine.
