木竹结构保温板外墙热湿性能及霉菌风险模拟预测
Prediction of Hygrothermal Performance and Mold Risk on Exterior Walls Using Domestic-Manufactured Structural Insulated Panels
摘要
Abstract
Predicting the hygrothermal performance and mold risk using the simulation model is a vital technical aspect for developing domestically produced,energy-efficient,and durable wood-bamboo building materials.This study focuses on Structural Insulated Panels(SIPs)exterior walls.By constructing a wireless high-precision hygrothermal data acquisition system and utilizing building hygrothermal performance software,measured and predicted data on indicators such as air temperature,relative humidity at the composite construction interface layer,and moisture content of internal and external cladding materials were obtained.The study analyzes the hygrothermal dynamic response of exterior walls at the Beijing's regional climatic conditions and predicts the risk of mold growth.The wireless high-precision building hygrothermal monitoring system operates stably,providing reliable data for real-time hygrothermal condition characterization and software simulation.Domestic wood-bamboo building materials used in SIPs exterior walls exhibit significant hygrothermal barrier effects,with an exceptional drying capability after extreme rainfall conditions.Precise predictions were made regarding the temperature,humidity,and moisture content distribution patterns within the SIPs exterior wall structural layers,as well as five-year trends.The total moisture content of the exterior wall and indoor temperature and humidity remains stable over the long term study period,during which the moisture content of recombinant bamboo and spruce cladding materials was consistently below 15%,therefore preventing mold growth.This research serves as a reference for the application and design optimization using locally produced wood and bamboo construction materials for the exterior wall systems.关键词
