基于CFD数值模拟的图书馆门厅中庭室内热环境分析与优化
|
摘要
门厅、走道等过渡区域高大空间空调制冷系统,如何获得舒适的夏季室内环境,满足节能要求,是一个难题。通过CFD软件模拟某大学图书馆门厅中庭的温度场和气流分布,更直观地呈现室内空调环境,分析计算结果,提出结论和针对性建议,以提高室内舒适度。对类似工程中高大空间夏季空调系统设计有一定的参考价值。
It becomes a challenge to address good indoor environment quality by air-conditioning and refrigeration systems in great space of transition area in energy-saving way. It simulates the temperature field and flow field of vestibule atrium of a university library by means of CFD software. Obtains indoor air-conditioned environment,analyzes calculated results and puts forward the targeted advices in order to enhance the indoor comfort. It has definite guidance and reference action to similar projects.
