大型植物园夏季喷雾系统设置对展览温室环境影响的模拟预测研究

Influence of Summer Spray System on Environment of Exhibition Greenhouse in Large Botanical Garden

植物温室通常以太阳辐射得热作为重要的升温热源,并提供植物生存所需的光照。但是在夏季太阳辐射过强时,仅应用自然通风手段仍无法有效降低室温的情况下,拟采用喷雾设施对温室进行降温。为了在设计和安装阶段前确定喷雾系统的效果,以上海某文化公园温室中的云之花园(P4场馆)为例,建立了展览温室的二维、三维仿真模型,通过对不同区域受喷雾系统管理区域进行模拟,探究夏季喷雾设置对展览温室环境的影响,其结论可为植物温室的喷雾系统设置提供一定参考。

Greenhouses typically use solar radiation as a key heating source and provide essential light for plant survival.However,during summer,when solar radiation becomes too intense,natural ventilation alone may not effectively reduce indoor temperatures.Therefore,it is proposed to use a spray system to cool the greenhouse.To assess the effectiveness of the spray system before the design and installation stages,a 2D and 3D simulation model of the exhibition greenhouse is developed,using the Cloud Garden(P4 Pavilion)in a greenhouse of a cultural park in Shanghai as a case study.By simulating the management of spray system areas in different regions,the impact of summer spray settings on the greenhouse environment is examined.The findings can offer valuable references for the configuration of spray systems in plant greenhouses.
