摘要:
为了阐明混凝土辐射地板的蓄释热性能,从时间常数的角度出发,通过实验分析混凝土辐射地板在蓄热、释热过程中温度及热量的响应特征。结果表明:供暖工况的时间常数快于供冷工况,混凝土辐射地板温度更易趋于稳定。当供水流量为6 L/min、1倍时间常数时,在环境温度(260±10) ℃、供水温度221 ℃的供冷工况下,120 mm厚辐射地板试块的平均蓄冷能力和释冷能力分别为216 W/m2和117 W/m2;在环境温度(165±10) ℃、供水温度298 ℃的供暖工况下,辐射地板试块的平均蓄热和释热能力则分别为837 W/m2和402 W/m2。供水流量对混凝土辐射地板的蓄释热能力影响较小,但通过改变供水温度能够明显提高混凝土辐射地板的蓄释热能力以及变化速率。随着供水温度和罩内空气温度之差的增大,累计蓄热量呈指数关系上升,累计释热量则呈线性关系上升。该研究结果可为混凝土辐射系统的设计、运行控制策略的制定提供依据。
