利用实验室墙体内壁敷设电热膜模拟实际墙体传热，通过表面热流计获得该壁面的总传热量，通过有效辐射计算方法和热平衡方法获得墙体净辐射热量和对流换热量，由此达到对流热量和辐射热量分离的目的。论文通过实验结果探讨墙体传热中对流辐射分离比例与墙体传热量、房间换气次数以及传热墙体附近气流形式的关联。结果表明：对流辐射分离中，对流比例受墙体传热量和换气次数的影响不大；受传热墙体附近气流形式影响很大，送风口下墙体传热量中对流比例远大于回风口下墙体传热量中的对流比例。

The paper used electric-thermal films in the wall body of building to simulate heat conduction of actual wall , and gained the total heat by heat flow meter on the inner surface of the laboratory walls . gains through the wall was measured .The net radiative heat gains and convective heat gains were calculat-ed by effective radiative method and heat balance method .It discussed the associations of the split ratio of convective heat and radiative heat amount through the wall , ventilation rates of laboratory and the airflow pattern near wall .Results indicated that among the separation of convection radiation ,the convection rates were little affect by amount of heat transfer and ventilation times ,whereas the airflow pattern greatly influ-enced the the convection rates .The convection ratios of the wall under the air supply outlet were far high-er than that of wall body under air return outlet .
