This paper presents exergo-economic and enviro-economic assessment of a novel building integrated photovoltaic thermal-compound sensible rotary heat exchanger (BIPVT-SRHX) system. The innovative BIPVT-SRHX system preheats/precools the outdoor air in winter/summer and generates electric power. The performance of the system are analyzed from the energy/exergy viewpoints for Kermanshah, Iran climatic conditions. Then, the multi-objective genetic algorithm (MOGA) optimization is used to optimize to determine the optimum values of geometric and operating parameters in order to maximize the annual average exergo-economic and enviro-economic aspects of the system. The considered geometric and operating parameters include the length, width and depth of the air channel located underneath the PV modules, the air mass flow rate, and the diameter, rotational velocity and length of the SRHX. Moreover, the annual performance of the optimized and non-optimized BIPVT-SRHX systems are compared. The results showed that the annual average exergo-economic and enviro-economic aspects of the optimized BIPVT-SRHX system are 0.0076 $/annum and 246.9 kWh/$, respectively. Furthermore, it was found that the annual average enviro-economic aspect, annual average exergo-economic aspect, and yearly sum of CO mitigation of the optimized BIPVT-SRHX system are respectively 36.8%, 23.1% and 37.7% higher than the non-optimized system.
本文对一种新型的建筑集成光伏光热复合显热旋转热交换器（BIPVT-SRHX）系统进行了火用经济和环境经济评估。该创新的 BIPVT-SRHX 系统在冬季/夏季预热/预冷室外空气，并发电。本文从能量/火用的角度分析了伊朗克尔曼沙阿气候条件下该系统的性能。然后，采用多目标遗传算法（MOGA）对系统进行优化，以确定最佳的几何和运行参数值，从而使系统的年平均火用经济和环境经济方面最大化。所考虑的几何和运行参数包括位于光伏模块下方的空气通道的长度、宽度和深度、空气质量流量以及 SRHX 的直径、旋转速度和长度。此外，还比较了优化和非优化 BIPVT-SRHX 系统的年性能。结果表明，优化后的 BIPVT-SRHX 系统的年平均火用经济和环境经济方面分别为 0.0076 美元/年和 246.9 kWh/年。此外，还发现优化后的 BIPVT-SRHX 系统的年平均环境经济方面、年平均火用经济方面和 CO 减排量分别比非优化系统高 36.8%、23.1%和 37.7%。
