辐射制冷涂料对住人集装箱热环境及能耗的影响

Effects of Radiative Cooling Coatings on Thermal Environment and Energy Consumption of Residential Containers

近年来集装箱凭借其移动性强、运输便捷、模块化建造速度快、成本低等优势在建筑领域广泛应用,而大多数集装箱由于构造简单,其围护结构的热工性能较差。将辐射制冷涂料应用于小型住人集装箱,并开展热工性能实验研究,结果表明辐射制冷涂料在夏季可使屋顶温度最大降低6.0℃,调节室内热环境;同时,为探索辐射制冷涂料在不同热工分区的适用性,选取典型城市,开展集装箱能耗特性仿真模拟,发现辐射制冷涂料更适用于以制冷为主的夏热冬暖区和夏热冬冷区,全年分别节能9.69kWh/m^(2)和1.44kWh/m^(2)。

In recent years,containers have been widely used in the construction field with their advantages of strong mobility,convenient transportation,fast modular construction and low cost,while most containers have poor thermal performance of their enclosures due to their simple structure.In this paper,radiative cooling coatings are applied to small residential containers,and thermal performance experiments are carried out.The results show that radiative cooling coatings can reduce roof temperature up to 6.0℃in summer,and regulate indoor thermal environment in summer.At the same time,in order to explore the applicability of radiative cooling coatings in different thermal zones,typical cities were selected to carry out simulation of container load characteristics,and it was found that radiative cooling coatings were more suitable for hot summer and warm winter areas and hot summer and cold winter areas where refrigeration energy consumption was the main focus,with an annual energy saving of 9.69kWh/m2 and 1.44kWh/m2,respectively.
