摘要
在进行建筑热过程模拟时,太阳辐射对于室内热平衡有很大影响,对于辐射供暖/供冷系统来说,太阳辐射对于室内热环境及系统效率的影响很大。正确的太阳得热分配算法可以更加准确预测能源效率和热环境及其舒适性。本文对射入室内的太阳辐射的分配算法进行了归纳总结,分析了各分配算法的优缺点及难易程度,并对几种典型分配算法进行了详细阐述,对不同类型的太阳辐射在室内的分配提出了建议,为进行建筑热过程模拟时太阳辐射分配算法的选取提供指导。
During building thermal process simulation,solar radiation has a large impact on building thermal balance. For radiant heating and cooling systems,solar radiation enormously affected both indoor temperature and the radiant system efficiency. Accuracy improvement for distribution algorithm of the incoming solar radiation on building envelopes would lead to more precise prediction of energy efficiency,thermal environment and thermal comfort. The purpose of this paper was to provide a guide for how to deal with the entering solar energy at the time of simulating buildings dynamic thermal process. In the paper,not only were the indoor distribution algorithms of incoming solar radiation summarized,but several typical distribution algorithms were elaborated and the merits and complexity of each assignment algorithm were analyzed. In addition,suggestions on appropriate allocation methods for different types of solar radiations were also presented.
