Air-conditioning systems make the most significant part of energy consumption in the residential sector. There is no denying that it is essential to produce a comfortable indoor thermal environment for residents in a building. The actual goal is to achieve thermal comfort level without putting too much cost on the ecological system by trying to conserve the amount of energy consumed. An effective way to help achieve such a goal is by incorporating thermal insulation in buildings. Thermal insulations help reduce thermal energy gained during the implementation of a desired thermal comfort level. This study aims to use an environmentally friendly nanoparticle of date pits to create thermal insulations that can be used in buildings. Different ratios of the nanoparticle of the date pits and sand composite were investigated. Fourier transform infrared spectroscopy and scanning electron microscopy were used to characterize the new materials. The material with nanoparticles of date pits and 50% by-volume epoxy provided good thermal insulation with thermal conductivity of 0.26 W⁄mK that could be used in the existing buildings. This has the potential to reduce the overall energy consumption by 4,494 kWh and thereby reduce CO2 emissions of a 570 m2 house by 1.8 tons annually. In conclusion, the future of using nanoparticles of date pits in construction is bright and promising due to their promising results.
空调系统是住宅部门能源消耗的主要部分。不可否认,为建筑物中的居民创造舒适的室内热环境是至关重要的。实际目标是在不消耗过多能源的情况下,努力节约能源消耗,从而达到热舒适度水平。实现这一目标的有效方法是在建筑物中使用隔热材料。隔热材料有助于减少在实现所需热舒适度水平期间获得的热能。本研究旨在使用环保的椰枣核纳米颗粒来制造可用于建筑物的隔热材料。研究了椰枣核纳米颗粒和沙复合材料的不同比例。傅里叶变换红外光谱和扫描电子显微镜用于表征新材料。纳米颗粒椰枣核和 50%体积比环氧树脂的材料提供了良好的隔热性能,导热系数为 0.26 W/mK,可用于现有建筑物。这有可能将 570 平方米房屋的总能耗降低 4494 kWh,从而每年减少 1.8 吨二氧化碳排放。总之,由于椰枣核纳米颗粒具有很有前途的结果,因此在建筑中使用椰枣核纳米颗粒具有光明的前景。
