This study explores the feasibility of implementing photovoltaic (PV)-powered cold room storage systems for fish preservation across multiple African nations. TRNSYS simulation software was employed to analyse the transient behaviour of cold rooms in 18 African countries, revealing significant regional disparities attributable to varying outdoor climatic conditions. These simulation results allowed the design of appropriate PV systems for powering the cold storage systems. The estimated PV capacities ranged from 1.49 to 3.64 kW tailored to each city's unique characteristics. System Advisor Model (SAM) was then used to simulate PV systems in the 18 sites. Technical and economic viability is assessed using two key metrics: Levelized Cost of Cold (LCOC) and Discounted Payback Period (DPP). While some cases exhibit favourable energy-related indicators, economic metrics are influenced by factors such as electricity tariffs and inflation. Environmental sustainability is a prominent aspect, with a majority of cases demonstrating significant reductions in CO emissions. This system's potential socio-economic impact extends continent-wide. A job creation potential analysis, primarily based on installed PV capacity, reveals variations among countries. In summary, this research underscores the potential of PV-powered cold room systems in African fisheries, shedding light on technical, economic, and environmental dimensions, with implications for sustainable development across the continent.

基于能源、经济、环境和社会维度对非洲鱼类保鲜太阳能制冷系统进行全面的多标准评估

本研究探讨了在多个非洲国家实施光伏 (PV) 供电的冷藏室存储系统用于鱼类保存的可行性。 TRNSYS 模拟软件被用来分析 18 个非洲国家冷藏室的瞬态行为，揭示了由于室外气候条件不同而导致的显着区域差异。这些模拟结果允许设计适当的光伏系统来为冷存储系统供电。预计光伏发电容量范围为 1.49 至 3.64 kW，根据每个城市的独特特征量身定制。然后使用系统顾问模型 (SAM) 模拟 18 个站点的光伏系统。使用两个关键指标评估技术和经济可行性：平准化冷成本 (LCOC) 和贴现投资回收期 (DPP)。虽然某些情况显示出有利的能源相关指标，但经济指标受到电价和通货膨胀等因素的影响。环境可持续性是一个突出的方面，大多数案例都表明二氧化碳排放量显着减少。该系统的潜在社会经济影响遍及整个非洲大陆。主要基于光伏发电装机容量的创造就业潜力分析揭示了各国之间的差异。总之，这项研究强调了光伏冷室系统在非洲渔业中的潜力，揭示了技术、经济和环境方面的问题，并对整个非洲大陆的可持续发展产生了影响。
