Active wall energy storage system for green building thermal management

刚性建筑结构（例如，墙、地板、柱子、屋顶等）可用作主动式显能/潜热储能系统（俗称主动墙结构）。能量可以存储在这种结构中来自可再生源（例如，太阳热能、废热等）并且可以在需要时使用。拟议的活动（为期：6个月）将调查在建筑物的结构部件中集成相变材料（PCM）的效果，这种集成将提高建筑物的整体能源效率。在本研究中，将对具有PCM的多孔介质进行分析建模，以了解PCM如何与多孔介质性质相互作用，即，材料、孔隙率和渗透率。将模拟PCM结构部件的计算流体动力学（CFD）建模，以获得多孔介质孔隙率和PCM的正确组合，从而优化熔化/冻结速率。将开发一个小规模的原型结构。PCM将集成在结构部件上。在结构构件内具有多孔介质的PCM将增强熔化/冻结，并且可以在建筑物中实现重要的节能。将进行实验测试，并与分析/模拟结果进行比较。这些渐进的研究和分析过程以及原型开发和验证将导致该技术在建筑系统中的商业化。牛顿集团将与圭尔夫大学合作开展拟议的研究，并利用研究结果调查商业案例， 开发优化的节能建筑。牛顿集团一直在使用技术，如，主动壁储能系统，集成池的温度冷却，和被动加热/冷却到他们的设计建造项目。这样的项目将有助于刺激绿色投资，绿色创新，并将为当地人民创造更多的就业机会和环境友好型技术。从长远来看，这种系统有可能降低安大略和加拿大的成本和碳足迹。

The rigid building structures (e.g., walls, floors, columns, roofs, etc.) can be used as active sensible/latent energy storages systems (commonly known as Active Wall Structure). Energy can be stored in such structures from renewable sources (e.g., solar thermal, waste heat, etc.) and can be utilized when required. The proposed activity (duration: 6 months) will investigate the effect of integration of phase change material (PCM) within the structural components of building where such integration will improve overall energy efficiency of the building. In the present study, analytical modeling will be carried out for a porous medium with PCM to understand how the PCM interacts with porous medium properties, i.e., material, porosity, and permeability. A Computational Fluid Dynamics (CFD) modeling of structural components with PCM will be simulated to obtain a right combination of porous medium porosity and PCM for optimization of melting/freezing rate. A small scale prototype structure will be developed. PCM will be integrated on the structural component. The PCM with porous medium inside structural component will enhance melting/freezing and could achieve important energy savings in buildings. Experimental testing will be carried out and compared with analytical/simulation results. These gradual research and analyses processes and prototype development and verification will lead to commercialization of this technology in building systems. Newton Group will partner with University of Guelph in the proposed study and use the results in investigating the business case for developing the optimized energy efficient buildings. Newton Group has been using technologies, such as, active wall energy storage system, integrated pond for temperature cooling, and passive heating/cooling to their design-build projects. Project like this will assist stimulation of green investment, green innovation, and will create more employment opportunities for local people and environment friendly technologies. In the long run, such system has the potential for cost and carbon footprint reductions in Ontario as well as in Canada.
