屋面保温材料热湿传递模型及RFID技术应用前景

Summary of Transfer Model of Roof Thermal Insulation Material and Application Prospect of RFID Technology

保温材料的参数变化会直接导致屋面保温系统的性能变化,从而造成节能浪费等一系列问题。对于屋面保温材料,其受到的不利因素主要为温度与湿度。通过对传热、传湿及其耦合模型的综述,得出了不同模型之间的差异与应用范围。同时为了达到实时监测的目的,建议在屋面保温材料上采用无线射频技术(RFID),根据材料参数的变化对屋面板进行替换操作,达到围护结构与主体结构同寿命的要求。

The change of thermal insulation material parameters could directly lead to the performance changes of roof thermal insulation system,which could cause a series of problems such as energy saving and waste.For roof insulation materials,the main disadvantageous factors were temperature and humidity.By reviewing the heat transfer,moisture transfer and their coupling models,the differences between different models and their application scope were obtained.At the same time,in order to achieve the purpose of real-time monitoring,it was suggested that the roof insulation material should be replaced by radio frequency identification devices(RFID)technology.According to the material parameters changing,the roof boarding could be changed.Therefore the requirement of the same life of the enclosure structure and the main structure could be obtained.
