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集成以减少建筑墙壁和天花板上的热负荷来自堪萨斯州四个机构和一个私营行业的研究小组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材料和相变材料(PCM)，可显著降低跨墙和天花板的峰值传热率，转移峰值冷负荷，并减少住宅和小型商业建筑的能源消耗。在本项目中，建筑隔热材料代表了相变材料的载体和支架，在其制造过程中被整合到隔热材料中。这种集成是通过创新的封装技术和重新配制的阻燃混合物实现的。这方面的研究很重要，因为美国每年用于为建筑物的空间供暖和制冷系统供电的能源约占美国年能源消耗的20%。因此，提高建筑构件(墙、天花板、地板)的能效的改进是非常必要的。这些改进将减少能源资源的使用，并最终减少温室气体排放。此外，这是发展低能耗建筑的重要一步，并通过将低温能量分配整合到高效墙壁和天花板组件的制造中，大大扩展了当前的做法。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，减少公用事业费用带来的节省，以及制造商新的有竞争力的企业。

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.
