项目概况随着太阳能热水系统向更大规模、更高温度与能量利用效率、与建筑更宪美结合等方向发展,储热水箱技术逐渐凸现持续供热能力不足、占用空间过大、工作温度和换热效率低等问题,迫切需要技术创新以保障太阳能热利用行业的快速可持续发展。因此,本项目提出在太阳能热水系统中应用相变储热技术的研究方案,利用相变储热材料高储热密度、相变温度恒定的特点,基于项目组在相变储热材料与数值模拟方向的优势技术,从传热工质、保温层和储热水箱三部分入手,开发出高相变胶囊体积分数、高工作温度的传热工质,隔
Project Overview With the solar hot water system to a larger scale, higher temperature and energy efficiency, combined with building a more constitutional beauty direction, the hot water tank technology gradually highlights the lack of sustained heating capacity, take up too much space, work Low temperature and heat transfer efficiency issues, there is an urgent need for technological innovation to ensure the rapid and sustainable development of the solar thermal industry. Therefore, the project proposes a research program of phase change heat storage technology in solar water heating systems. Based on the characteristics of high thermal storage density and phase transition temperature of phase change thermal storage materials, Simulation of the direction of the advantages of technology, starting from the heat transfer medium, insulation and storage of hot water tank to start three parts, the development of high phase change capsule volume fraction, high working temperature of the heat transfer medium, separated
