摘要
根据地板采暖的特点,建立数学模型,采用有限差分法对地板层内部的非稳态传热过程进行计算,并就地板层内部、地板表面温度场的分布及其影响因素进行分析,并对预热时间进行研究,为地板辐射采暖系统的推广和应用奠定一定的理论基础。
According to the feature of the radiant floor heating system, a mathematical model was cstablishexi. The finite difference method was taken to calculate the floor interior unstable condition heat transfer process. The floor surface temperature field distribution and its the influence factor wcrc analysed. Studying the preheat time, a certain rationale of the floor radiation heating system promotion and application wcrc provided.
