摘要
随着建筑能耗形势愈加严重,体育馆作为特殊的能耗类型,越来越受到关注。本研究目的在于探讨可开闭屋顶形式的体育馆对于气候的适应性,进而探讨其能否有效达到节能的目的。本文基于上海嘉定同济体育馆,利用CFD数字模拟的方法,采用airpak流体力学软件对体育馆在开闭屋顶2种工况条件下进行模拟分析,以体感温度以及热舒适度作为衡量条件,对室内的环境进行评价。结果表明,屋顶的开闭可以有效的影响室内环境,屋顶开启时室内通风增加,温度降低约2℃,且热舒适度从温暖变为舒适。屋顶关闭时,通风减弱,温度升高,在夏季不利于节约空调能耗。由此可知,在夏季,开闭屋顶体育馆可以有效的根据气候调节内部环境,改变室内热舒适度,有利于节约能耗。
With the building energy consumption situation becoming more serious,gymnasiums,as a special type of energy consumption,are receiving more and more attention. The purpose of this study is to explore the adaptability of gymnasiums whose roofs can be opened and closed according to the climate,and then to explore whether the purpose of energy conservation can be achieved in this way. Based on Shanghai Jiading Tongji Gymnasium,this paper takes the method of CFD digital simulation and uses airpak fluid mechanics software to simulate and analyze the gymnasium under the conditions of open and closed roof. The body temperature and thermal comfort are taken as the measurement conditions for the indoor environment, so as to conduct the evaluation. The results show that the opening and closing of the roof can effectively affect the indoor environment.Specifically,when the roof is open,the indoor ventilation will increase,the temperature will decrease by about2 ℃,and the thermal comfort will change from being warm to being comfortable. When the roof is closed,the ventilation will be weakened and the temperature will rise,which is not conducive to preventing air-conditioning energy consumption during the summer. It can be seen that in summer,opening and closing the roof of the gymnasium can effectively help to adjust the indoor environment according to the climate,change the indoor thermal comfort,and save energy.
