摘要
建立了低温地板辐射供暖系统的传热过程的数学模型,通过数值模拟,用有限元法计算了平板内的温度场;以一个动态仿真程序得出了不同供回水温度和排管间距下的地板表面最高温度、室内实感温度、热流密度、预热期等参数。
Establishes a heat transfer model of the system and obtains the temperature field in the
floor plane with the finite element method. Using a dynamic simulation programme predicts values
of the maximum floor surface temperature, perceived room temperature, heat flowrate per unit floor
area, preheat time etc. under different supply and return temperature and spacing of the tubes,
illustrating the system's features in comfort and energy efficiency.
