摘　　要：本文以上海某游泳馆为研究对象,采用流体力学软件CFD与能耗分析软件EnergyPlus交互运用的方法,对游泳馆进行数值模拟和能耗分析。首先运用EnergyPlus对游泳馆下送风气流组织进行设计日模拟,并以模拟数据作为边界条件,利用CFD对游泳馆热湿环境进一步模拟分析,将分析数据作为EnergyPlus的输入参数。然后分析讨论影响建筑能耗的主要因素:玻璃幕墙遮阳性能、新风比、机组性能系数(COP)等,采用EnergyPlus对游泳馆进行能耗模拟并计算全年能耗费用。结果表明,在保持其他影响因素不变的前提下,分别单独改变某一种影响因素,耗电量分别减少4.3%,6.8%,21.2%;耗气量在新风比因素改变的情况下减少50%,其他因素影响变化不大;全年总能耗费用分别减少1.3%,34.6%,7.6%。Taking a natatorium in Shanghai as the original model, energy consumption analysis were conducted on it by using the CFD software together with EnergyPlus. Firstly, EnergyPlus was used to calculate the cooling of a natatorium with under floor air supply system in design day. Then the obtained wall temperatures were set to be the boundary conditions to further stimulate the indoor thermal environment. And then, the air temperature was input into EnergyPlus to simulate its annual energy consumption. The influence of such factors as SHGC, fresh air ratio, COP of water chillers on building energy consumption and cost were calculated. Results show that the change in any individual factor may cause electrical power consumption to decrease by 4.3%, 6.8%, 21.2%. And gas consumption was decreased by 50% in the influence factor of fresh air ratio, and little changed in other factors. The total annual energy cost decrease by 1.3%, 34.6%, 7.6%.
