During the summer in the UAE, the daytime temperature rises up to 50 °C and the abundance of solar radiation hinders crop growth, whose cultivation period is approximately 5–6 months (usually from May to October). This study attempted to reduce the uncultivated period to 2–3 months by implementing an exterior shading and evaporative cooling system. Based on the results of comparison (through simulation) between the effects of reducing the temperature and cooling load on the cladding material, exterior shading, and fan and pad evaporative cooling system in smart farms in the UAE, the capacity of refrigerators and thermal storage tanks in greenhouses can be determined. Moreover, the peak cooling load according to the cladding material type, shading rate, and use of fan and pad was analyzed. When an exterior shading rate and fan and pad system efficiency of 50% and 90%, respectively, were applied to poly methyl methacrylate (PMMA), the peak cooling load decreased by 87.9% in comparison to when a general polyolefin (PO) film was applied.

阿联酋智能温室降温技术降温效果对比分析

在阿联酋的夏季,白天气温高达 50°C,丰富的太阳辐射阻碍了作物的生长,其种植期约为 5-6 个月(通常为 5 月至 10 月)。本研究试图通过实施外部遮阳和蒸发冷却系统将未开垦期缩短至 2-3 个月。基于降低温度和冷却负荷对阿联酋智能农场的覆层材料、外部遮阳以及风扇和垫蒸发冷却系统的影响之间的比较(通过模拟)结果,冰箱和蓄热罐的容量在温室中可以确定。此外,根据覆层材料类型、遮光率以及风扇和垫的使用,分析了峰值冷负荷。
