摘　　要：采暖设备的使用过程中,热舒适性是一项重要的用户使用指标。本文以江苏省典型普通住宅采暖系统为研究对象,运用计算机流体动力学(Computational Fluid Dynamics,CFD)数值模拟技术建立物理模型,对室内温度场与热舒适度进行分析。同时实验采集温度、湿度等相关参数,分析地板辐射采暖与散热器采暖的热舒适度差异。CFD数值模拟与实验结果相比较发现:相同室外环境下,地板辐射换热采暖温度波动范围小于散热器采暖,地板辐射换热采暖较散热器采暖更加舒适。Thermal comfort is increasingly valued and becomes one of the important service indexes during theusage of heating equipment.In this paper,the heating system of the typically ordinary residential in JiangsuProvince has been taken as the research object.A physical model has been established by numerical simulation ofComputational Fluid Dynamics(CFD)for the sake of analysis of indoor temperature field and thermal comfortdegree.Meanwhile relevant parameters such as temperature and humidity have been collected for furthercomparative study on differentiation of thermal comfort between floor heating and radiator heating.The resultsindicate that the temperature fluctuation range of the system is less than the one of the radiator heating system inthe same outdoor environment,and then the floor radiant heating system provides more comfortable moderationthan the radiator heating system.
