摘　　要：本文主要是关于蓄能冷却吊顶在不同风速下换热情况的实验研究。由于蓄能材料融化时温度不变,可避免一般辐射吊顶实验中吊顶温度不均匀及温度变化幅度和变化频率较大的情况。实验中比较了相同吊顶温度、不同风速下,室内温度的变化情况;计算了辐射换热量和对流换热量的变化,以及辐射量的比例。This paper is mainly about the energy storage cooling ceiling experimental study of heat transfer of energy storage cooling ceiling in different flow rate.As the melting temperature of storage materials is invariable,it can avoid the situation that the temperature of cooing ceiling is not uniform,range is large and frequency is high in traditional experiment.It compares indoor temperatures in the same temperature of ceiling and different flow rate,computes the change of heat transfer in radiation and convection,and the rate of radiation.
