为构建简便有效的基于建筑形体要素的太阳能采暖潜力评价方法,以额济纳旗、西安为例,开展西部太阳能采暖效率计算方法研究。将建筑高宽比、高长比、南向窗墙面积比作为太阳能采暖热利用关联紧密的形体要素,经过正交试验、动态能耗模拟、数理统计分析等方法得到基于建筑形体要素的建筑太阳能采暖潜力函数。将该函数图形化表达发现增大建筑高宽比、南向窗墙面积比均能优化建筑太阳能采暖效率。给出在额济纳旗和西安提升建筑太阳能采暖效率的有效措施。该研究并非旨在取代动态模拟工具,而是为建筑设计初期构建一种简便的太阳能采暖设计的热性能分析方法。
Abstract
In order to establish a simple and effective solar heating potential evaluation method based on building shape elements, taking Ejina Banner and Xi'an as examples, a study on the potential of solar heating in western China was carried out. The height-to-width ratio, height-length ratio, and south-facing window-to-wall ratio of the building are regarded as the key physical elements closely related to the heat utilization of solar heating. After orthogonal experiments, dynamic energy consumption simulation, and mathematical statistical analysis, building solar heating potential function based on building shape elements is obtained. By graphical expression of the function, it is found that increasing the aspect ratio and the south-facing window-to-wall ratio are conducive to improving building solar heating efficiency. Effective measures to improve the solar heating efficiency of buildings in Ejina Banner and Xi'an are given. This research is not intended to replace dynamic simulation tools, but to construct a simple thermal performance analysis method for solar heating design at the initial stage of building design.
