对两种不同形式的辐射吊顶板的换热性能进行了实验研究.测试结果表明,并联毛细管型辐射吊顶换热性能优于串联盘管型辐射吊顶,在供回水平均温度与室温之差为8℃时,毛细管型辐射吊顶供冷量为64.4W/m2,盘管型为55.0W/m2.对于同一辐射吊顶板,在同样的供回水平均温度与室温差下,供冷量与供热量相差不大于10%,因此从供冷量可以初略推算出供热量.所测试的两种辐射吊顶板的供热量、供冷量与供回水温度和室内温度之差接近线性关系,因此可以推算辐射吊顶在不同供回水温度下的换热量.另外,毛细管型辐射吊顶比串联盘管型辐射吊顶板的流动阻力小.

The heating and cooling capacity of two different radiant ceilings are tested. Testing results show that the cooling performance of the radiant ceiling with parallel capillary coil is better than the series-connected coil type, when the temperature difference between the room and the average temperature of the supply and return water is 8℃, the cooling capacity of the capillary type radiant ceiling is 64.4W/m2, and the coil type is 55.0 W/m2. For the same radiant ceiling in the same temperature difference between the room and the average temperature of the supply and return water, the difference between cooling and heating capacity is no more than 10%. In addition, the radiant ceiling with parallel capillary tubes has less flow resistance than the series-connected coil ceiling.
