摘　　要：合理的采暖方式不仅使人体舒适,而且有利于有效利用能源。以兰州地区某公共建筑作为研究对象,通过流场模拟软件Fluent airpak,建立房间的数学模型与物理模型,对室内的温度场、速度场及热舒适性进行分析。得出了室内温度分布云图、速度云图、PMV分布图。对比分析了2种采暖方式的差别,低温地板辐射采暖相较于散热器采暖,在温度、风速、热舒适等方面具有极大的优势,而且低温地板辐射采暖可以利用低品位能源作为热源,节约能源,具有很大的推广意义。Reasonable heating not only means making human body comfortable, but also contributes to the rational utilization of energy. Taking public buildings in Lanzhou as the research object, through the flow field simulation software - Fluent airpak, the mathematical model and physical model of the room are established, and the indoor temperature field, velocity field and thermal comfort are analyzed. The results show the indoor temperature distribution, velocity cloud, PMV distribution and the differences of two heat-ing methods. Compared to the heating of radiator, low temperature radiant floor heating not only has great advantages in temperature, wind, thermal comfort, etc, but also can make full use of low grade energy as heat resource. In addition, low temperature radiant floor heating has a great promoting significance.
