【摘要】 储能技术能够促进能源的优化利用,已成为国内外研究的热点,在全球范围节能减排的大趋势下,各能耗领域关于储能技术的研究显得至关重要。本文对相变储能房间节能应用技术进行了归纳,对各种技术的应用优势与难点进行了分析总结。针对目前相变储能理论与技术研究的单一性,从相变储能房间能源优化利用的角度出发,侧重太阳能采暖的利用,提出了适合寒冷地区的“相变储能房间热集成技术”的思想及具体方案,以沈阳建筑大学原建设指挥部为例进行了效益分析。针对相变储能热水采暖地板在蓄热期间容易出现的供暖能力偏低的问题,提出了一种双层毛细管网加热的新型相变储能热水采暖地板系统,借助有限元分析软件ANSYS,在合理简化之后建立了三维传热模型,分析了相变储能热水采暖地板的蓄放热性能。在理论分析的基础上,本文选取选择癸酸作为相变材料,通过对相变材料进行封装测试,比较分析了两种地板相变储能模块的制作,在此基础上搭建了新型相变储能热水采暖地板系统,并进行了测试与分析工作,得出了相变储能地板热水采暖系统的实际蓄放热性能以及其对房间热舒适性的影响,实际测试发现相变储能地板蓄放热性能良好,在蓄热8小时放热16小时的稳定间歇循环中,室内空气温度基本能保持在16℃以上,室内空气温度状况良好。此外,本文在建筑南立面搭建了自行研制的太阳能空气集热器,构成了相变储能房间太阳能综合供暖的实验平台,该太阳能空气采暖系统在冬季可以辅助相变储能热水地板采暖,在夏季可以进行夜间机械通风蓄冷。对该相变储能房间太阳能综合采暖系统的间歇采暖效果进行了测试分析,证明了“相变储能房间热集成技术”应用的可行性,从而为太阳能采暖的利用,电力系统峰谷差问题的解决,为提高人民居住环境和建筑节能工作提供新的途径。更多还原

【Abstract】 Energy storage technology can optimize the utilization of energy, so it becomes the hot research point at home and aboard. Under the huge trend of worldwide energy conservation and C-mission reduction, it seems quite important for the research of energy storage technology. This paper summarized the technologies used in phase change energy storage room and analyzes their advantages and disadvantages. Regarding to the singularity of PCES technology and focusing on the use of solar heating, this paper presented an idea of“thermal integration technology phase change energy storage room”and its specific program for cold areas from the point of optimal use of energy. Taking a small second-floor building as an example, the benefit of the program was analyzed.Regarding to such problem as heating deficiency in the period of heat-storing for PCES floor, this paper proposed a kind of new PCES floor system taking a double capillary network as heating end. With the help of finite element analysis software ANSYS and through reasonable simplification, this paper set up a three-dimensional heat transfer model and analyzed the characteristic of storing and releasing heat of the PCES floor.Based on the theoretical analysis, this paper established a kind of actual new PCES floor system. Capric acid was chosen as phase change material. Before establishing the experiment platform, the PCM was tested and two kinds of packaging method were tried. After that, the new PCES floor system was tested and analyzed. The characteristic of storing and releasing heat of the PCES floor and its influence on indoor thermal environment were gotten.In addition, a self-developed solar air collector was integrated into the south wall of the small building, which constituted a solar heating integrated experimental platform. This solar air heating system could not only assist the PCES floor system in winter but also provide night mechanical ventilation in summer. The effect of intermittent heating for the solar heating integrated system was tested and analyzed, which proved the feasibility of application of "phase change thermal energy storage room integration technology". The research provided a new way for solar heating, solving the peak and valley problem for electrical system, providing more comfortable living environment and achieving building energy efficiency.更多还原
