摘要
根据换热器设计的ε-NTU方法和肋片理论,建立了地板辐射换热器传热过程的准一维模型,利用该模型进行了计算并与实验数据对比,结果表明该一维模型可用于地板辐射换热器的设计和校核计算,且该模型中较为直观地体现了流量对于系统性能的影响。
According to the fin theory and method, a quasi-one-dimensional numerical model of low temperature radiant floor heating was established and proved by experimental study that it can be used for the design of radiant floor heating system. In this model, the influence of flow rate on performance of radiant exchanger was reflected intuitively.
