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。
During the use of heating equipment, thermal comfort is an important indicator of user usage. In this paper, a typical residential heating system in Jiangsu Province is taken as the research object. The physical model is established by Computational Fluid Dynamics (CFD) numerical simulation technology, and the indoor temperature field and thermal comfort are analyzed. At the same time, the experimental parameters such as temperature and humidity were collected to analyze the difference of thermal comfort between radiant floor heating and radiator heating. Compared with the experimental results, the CFD simulation results show that under the same outdoor environment, the radiant floor heating temperature fluctuation range is less than that of the radiator, and the floor radiant heat exchange heating is more comfortable than the radiator heating.
