新型相变材料的基本热性能分析

摘要

In recent years,the energy consumption of buildings is becoming more and more seri-ous,in order to reduce energy consumption and improve energy utilization,the phase change energy storage can be used as a new and effective energy-saving technology for environmental protection. In this paper,the composite phase change materials are prepared by vacuum adsorption method, using decanoic acid and lauric acid as phase change materials and expanded perlite as matrix materials.The phase transition temperature is preliminarily determined by using the step cooling curve,temperature-wise instrument tests the tempering properties of composite phase change materials. It has important reference value for understanding and mastering the preparation of phase change material,the prepara-tion of composite phase change material,the characteristics of composite phase change material and its application prospect in architecture.%近年来,建筑能源消耗日益严重,为降低能源消耗、提高能源利用率,相变储能作为一种新型有效的绿色环保的节能技术,应运而生.本文以癸酸、月桂酸为相变材料,膨胀珍珠岩作为基体材料,采用真空吸附法制备出定型复合相变材料.采用步冷曲线法初步确定相变温度,温度智能仪表测试定型复合相变材料的调温性能.对于了解和掌握二元相变材料的配制、复合相变材料的制备、复合相变材料的特性、及其在建筑方面的应用前景具有较为重要的参考价值.
