数值模拟在工业建筑照明节能中的应用研究

A study on numerical simulation used in lighting energy saving of industrial buildings

利用计算机数值模拟技术,对某车间室内照明的初始设计方案和考虑灯具选型、数量、布置方式等因素的优化设计方案分别进行了数值模拟,并以照度和照明功率密度为主要指标进行了节能分析。研究结果表明,优化后的设计方案与初始设计方案相比,灯具数量减少了54.6%,照明节电率可达56.5%,极大提高了照明效率。

Using computer numerical simulation technology, this paper respectively made numerical simulation to the initial design scheme of a workshop indoor lighting and the optimum design thinking of lamp selection, quantity, layout ways and other factors, and made energy saving a- nalysis taking illumination intensity and lighting power density as main index. The results showed that the optimized design scheme compared with initial design scheme, the number of lamps reduced 54.6%, the lighting energy-saving rate reached 56.5%, greatly improved the lighting efficiency.
