PATH: Optimal Integration of Renewable and Phase Change Materials in Insulation Systems for the Reduction of Thermal Loads Across Building Walls and Ceilings

摘要：可再生材料和相变材料在隔热系统中的最佳整合，以减少建筑墙壁和天花板的热负荷。来自堪萨斯州四家机构和一家私营企业的研究人员正在开发下一代节能建筑隔热系统。这些系统集成了可再生和相变材料（pcm），以显着降低墙壁和天花板的峰值传热率，转移峰值冷却负荷，并减少住宅和小型商业建筑的能源使用。在这个项目中，建筑保温材料代表了pcm的载体和载体，pcm在制造过程中被整合到保温材料中。这种整合是通过创新的封装技术和重新配制的阻燃混合物实现的。这一领域的研究很重要，因为美国每年用于建筑空间供暖和制冷系统的能源约占全国年能源消耗的20%。因此，提高建筑元素（墙壁、天花板、地板）的能源效率的改进是非常必要的。这些改进将减少能源的使用，最终减少温室气体的排放。此外，这代表了低能耗建筑发展的重要一步，并通过将低温能源分配整合到高效墙壁和天花板组件的制造中，显着扩展了当前的做法。对社会的潜在好处包括为消费者提供更广泛的产品选择，节省能源的机会，减少水电费带来的节省，以及为制造商提供新的竞争企业。

AbstractOptimal Integration of Renewable and Phase Change Materials in Insulation Systems for the Reduction of Thermal Loads Across Building Walls and Ceilings A team of researchers from four Kansas institutions and agencies and one private industry are developing the next generation of energy efficient building insulation systems. These systems integrate renewable and phase change materials (PCMs) to significantly reduce peak heat transfer rates across walls and ceilings, shift peak cooling loads, and reduce energy use in residential and small commercial buildings. In this project, the building thermal insulation represents the carrier and holder of the PCMs, which are integrated into the insulation during its manufacturing process. This integration is made possible through innovative encapsulation techniques and reformulated fire-retardant mixtures. Research in this area is important because the energy spent annually to power space heating and cooling systems in buildings in the U.S. represents about 20% of the annual energy consumed in the country. Therefore, improvements that increase the energy efficiency of building elements (walls, ceilings, floors) are greatly needed. These improvements will reduce energy resource use and ultimately decrease emissions of greenhouse gases. In addition, this represents an important step in the development of low-energy buildings and significantly extends current practices by integrating low-temperature energy distribution into the manufacture of high-efficiency wall and ceiling components. The potential benefits to society include a wider range of product choices for consumers, opportunities to save energy, savings resulting from reduced utility bills, and new competitive ventures for manufacturers.
