摘 要 本文对地板辐射供冷地板构造层温度场进行了数值模拟，并结合实验得出其温度分布，讨论了保温层对构造层温度分布的影响。通过实验测定了地板辐射供冷室内温度场的分布情况，得出供水温度对室内温度的影响。 关键词 地板辐射供冷；数值模拟；温度分布；结露 The Study On The Floor Structural Layer And Indoor Temperature Field Of Radiant Floor Cooling Tonghua Zou Lijun Ma Tianjin University of Commerce, Tianjin Key Laboratory of refrigeration technology,300134 Abstract: The Numerical simulation on the temperature field of the floor structural layer which was adapted radiant floor cooling. The temperature distribution is got by combining the results of numerical simulation and experiments. Insulation of floor structural layer has a certain extent to the temperature distribution. The indoor temperature field distribution of floor radiant cooling can be done through a series of experiments. And the Indoor temperature field distribution was influenced the supply water temperature. Keywords: Radiant floor cooling, numerical simulation, temperature distribution, condensation
