摘要
为了改善建筑外窗带来的建筑能耗问题,人们开始注重研发新型节能玻璃产品,全钢化真空玻璃作为新生的节能玻璃产品,拥有良好的保温隔热性能,其内部真空状态消除了大部分热量对流和传导,而低辐射膜降低了辐射传热。本文以全钢化真空玻璃为研究对象,通过建立传热物理模型对其传热机理进行分析,得到了全钢化真空玻璃传热性能的关键影响因素。在此基础上,运用层次分析法确定评价因素指标权重,利用加权平均模型对五组方案进行模糊综合评价,并通过试验验证模糊综合评价模型的有效性。结果表明:第五组全钢化真空玻璃的传热性能最好,模糊综合评价模型与试验所得结果相一致,为全钢化真空玻璃传热性能方案的优选提供了可行性参考。
In order to improve the energy consumption issues caused by building exterior windows, people have begun to pay attention to the development of new energy-saving glass products. Fully tempered vacuum glass, as a new energy-saving glass product, has good insulation performance. Its internal vacuum state eliminates most of the heat convection and conduction, while low radia-tion film reduces radiation heat transfer. This article takes fully tempered vacuum glass as the research object, analyzes its heat transfer mechanism by establishing a heat transfer physical model, and obtains the key influencing factors of the heat transfer performance of fully tempered vacuum glass. On this basis, the Analytic Hierarchy Process is used to determine the weights of evaluation factor indicators, and a weighted average model is used to conduct a fuzzy comprehensive evaluation of five groups of schemes. The effectiveness of the fuzzy comprehensive evaluation model is verified through experiments. The results indicate that the fifth group of fully tempered vacuum glass has the best heat transfer performance, and the fuzzy compre-hensive evaluation model is consistent with the experimental results, providing a feasible reference for the optimization of heat transfer performance schemes of fully tempered vacuum glass.
