摘　　要：供暖方式不同时,房间换气次数的高低将对室内热环境产生明显的影响。本文用数值模拟的方法对三种典型供暖方式在不同换气次数下的室内热状况分别进行了模拟和分析。结果表明,在换气量较大时,三种供暖方式对应的室内气温和热舒适指标PMV分布将具有不同的特征。因此,对于大换气量房间,供暖方式的选择应综合考虑热环境特点。Indoor thermal environment are affected by heating mode and air exchange rate intensively. In order to characterize the thermal features of a heating room with different air exchanges,indoor thermal environment was simulated and analyzed under three typical heating modes by employing the method of computational fluid dynamics, respectively. The result shows that the indoor air temperature and PMF distributions have different characteristics under different heating modes and air exchange rates ,and the heating mode in high air exchange rooms should be selected by integrated considering of temperature and PMV distributions.
