孤立区域光伏空调建筑自持化能量平衡优 化研究 ☆ 西安建筑科技大学 王登甲 吴航 刘艳峰 王莹莹 刘加平 摘 要：依靠建筑自身收集面进行光伏组件铺设以实现建筑空调系统自持化运行，是偏 远及孤立区域有效的建筑用能策略。对于太阳能建筑来说，通过合理的建筑围护结构设计来 降低建筑冷负荷非常重要。本研究以海南省琼海市某综合楼为例，通过模拟得到几种热湿地 常见区节能方法的效果。并通过对建筑空调系统用能与光伏系统供能进行动态平衡理论分析， 在建筑能量平衡的基础上，提出了适用于空调系统的自持化光伏系统设计计算方法。最后， 应用此方法对综合楼几种围护结构条件下的匹配结果进行了分析，获得了光伏空调建筑的自 持化匹配优化结果。 关键词：建筑节能 光伏空调 光伏容量 建筑热工 自持化 A Study on the Energy balance and Optimization of the Self-sustained PV Air -conditioning Building in Isolated Area Wang Dengjia☆,Wu Hang, Liu Yanfeng, Wang Yingying and Liu Jiaping Abstract: It is an effective building energy strategy for remote and isolated areas which laying PV modules only rely on the building surface to achieve self sustained operation of building air conditioning system. For solar buildings, it is very important to reduce the cooling load by reasonable building envelope design. In this study, Qionghai city in Hainan Province, a building for example, the effect of several energy saving methods is obtained through simulation. And analyzed the dynamic balance theory of building air-conditioning system energy consumption and PV system energy supply, on the basis of building energy balance, puts forward the self-sustaining calculation and design method which is suitable for air-conditioning system. Finally, this method is applied to analyze the matching results under the condition of the comprehensive building envelope, and the self-sustained matching and optimization results of PV air-conditioning building are obtained.
