Active wall energy storage system for green building thermal management

刚性建筑结构(如墙、楼板、柱、屋顶等)可用作主动式显性/潜能型储能系统(俗称主动墙结构)。可再生能源(例如，太阳能、废热等)可储存在这种结构中。并可在需要时使用。拟议的活动(为期6个月)将调查将相变材料(PCM)整合到建筑物结构部件中的效果，这种整合将提高建筑物的整体能效。在这项研究中，将对含有相变材料的多孔介质进行解析建模，以了解相变材料如何与多孔介质属性相互作用，即材料、孔隙度和渗透率。用相变材料对结构部件进行计算流体动力学(CFD)模拟，以获得多孔介质孔隙率和相变材料的正确组合，以优化熔融/冻结速度。将开发一个小规模的原型结构。PCM将集成在结构部件上。结构构件内部带有多孔介质的相变材料将促进融化/冻结，并可在建筑中实现重要的节能效果。将进行实验测试，并与分析/模拟结果进行比较。这些逐步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在拟议的研究中合作，并将结果用于调查以下业务案例 发展优化节能建筑。牛顿集团一直将主动墙体储能系统、一体化池温降温、被动式供暖/降温等技术应用于其设计建造项目。这样的项目将有助于刺激绿色投资、绿色创新，并将为当地人创造更多就业机会和环保技术。从长远来看，这种系统在安大略省和加拿大都有降低成本和减少碳足迹的潜力。

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.
