摘　　要：文章基于焓-多孔介质方法,建立了植物工厂相变围护结构数值模型,研究了相变围护结构内部的相变材料在室外温度周期性变化与相变层内热媒管间歇性供热共同作用下的周期性熔化与凝固特性,探索了泡沫金属的填充对相变围护结构储能效果的强化作用。结果表明,泡沫金属的填充能够有效强化相变围护结构的储热与放热特性,泡沫金属填充量越多储热速率越快。对比横向与纵向的泡沫金属填充方式发现,在热媒管之间靠近室内的一侧填充泡沫金属为最优的设置形式。Based on the enthalpy-porous media method,a numerical model of a phase change enclosure structure for plant factories was established.The periodic melting and solidification characteristics of the phase change material within the phase change enclosure structure under the combined action of periodic changes in outdoor temperature and intermittent heating of the heat pipe within the phase change layer were studied.The enhancement effect of foam metal filling on the energy storage performance of the phase change enclosure structure was explored.The results show that the filling of foam metal can effectively enhance the heat storage and release characteristics of the phase change enclosure structure.The more foam metal is filled,the faster the heat storage rate.By comparing the horizontal and vertical foam metal filling methods,it was found that filling the foam metal on the side of the heat pipe closer to the indoor side is the optimal configuration.
