多曲面太阳能聚光对张家口市建筑室内热环境的调节作用研究

Study on the Regulating Effect of Multi-Curvilinear Solar Concentration on the Indoor Thermal Environment of Buildings in Zhangjiakou City

多曲面太阳能的应用与发展越来越受到社会各界的广泛关注,本文以张家口市建筑为研究对象,分析多曲面太阳能聚光对该市建筑室内热环境的调节作用。利用新型组合的抛物面集光设施、反射平面镜、槽底抛物面的集光设备、高温太阳能接收设备等组建多曲面太阳能聚光集热体系,并详细研究了该体系的工作程序;将多曲面太阳能聚光建筑取暖系统,通过串并联的模式,与集热模块进行连接,实现建筑室内热环境的调节;利用铜板测温法,对建筑室内温度分布进行测量,沿着建筑进深方向,于室内的中心进行垂直截面,每50cm设置一个铜板,进而测量出室内温度空间分布。根据上述过程,得到的实验结果表明,室内的其他温度、风门的开启和关闭及墙外表温度对室内热环境的调节作用不明显;多曲面太阳能聚光和其他温度耦合作用下,室内热环境明显产生了比较大的变化;说明多曲面太阳能聚光对建筑室内热环境具有极佳的调节所用。

The application and development of multi-surface solar energy has drawn more and more attention from all walks of life. Taking Zhangjiakou buildin g as the research object,this paper analyzes the regulatory effect of multi-surface solar concentration on the indoor thermal environment in this city.The multi-surface solar concentrating heat collecting system was established by using a new combination of parabolic concentrating facilities,reflecting mirrors,collecting equipment with paraboloid at the bottom and high-temperature solar receiving equipment. The working procedure of the system was studied in detail. The multi-surface solar energy poly Light building heating system,through series and parallel mode,connected with the heat collection module to achieve the regulation of the building indoor thermal environment; the use of copper temperature measurement method to measure the indoor temperature distribution in the building,along the building depth direction,in the indoor center For a vertical section,set a copper plate every 50 cm, and then measure the spatial distribution of the indoortemperature. According to the above process,the experimental results obtained show that the indoor temperature,the opening and closing of the damper and the wall surface temperature do not have any significant effect on the indoor thermal environment. The multi-surface solar concentration and Under the coupling of other temperatures,the indoor thermal environment obviously has a big change. It’s shown that the multi-surface solar concentration on the indoor thermal environment with excellent regulation.
