摘要
本文以热电模拟为基础,建立了模拟通风屋面下房间的室内热状况的数理模型,它不仅解决了多年来对通风屋面热性能的研究多处于实测而难以预测与定量分析的问题,也为建立一套完整的自然通风建筑热工设计软件包奠定了基础。模型用5种实际屋面的传热模拟得以验证;文章还给出了用该模型对福建省三种典型屋面的传热模拟与结果分析,它显示了架空层中气流通畅程度对室内热舒适性的影响。
Based on Thermoelectrical circle theory, a Predictive model for simulating ther- mal performance under Ventilated roof structure is established. Instead of the traditional method of measuring in situ, it solves the problems in a predictive and quantiative way. It also sets a foundation to the sofwares of thermal design tool for natually ventilated building, the results of simulation for five kinds of practical roofs show that the model is successful. The simlation results of three typical kinds of roofs in Fujian show the degree of influence of ven- tilation state within the roofs structure to the comfortness of the room.
