摘　　要：介绍了层状、条状两种结构的相变蓄能地板。建立了相变蓄能地板的计算模型，数值模拟了不同供水温度下两种结构相变蓄能地板的表面平均温度随加热时间的变化，相变材料的填充量及地面装饰材料对条状相变蓄能地板表面平均温度的影响。在满足同样供热需求的前提下，采用条状相变蓄能地板更经济、实用。当供水温度为50～55℃时，条状相变蓄能地板表面温度达25～29℃，符合人体热舒适性的要求。The phase-change energy storage floor with layer and strip structures is introduced. The calculation model of phase-change energy storage floor is established. The variation of average surface temperature of phase-change energy storage floor with two structures with heating time at different water supply temperatures, and the influence of filling quantity of phase-change material and decorative floor materials on average surface temperature of phase-change energy storage floor with strip structure are simulated numerically. On the premise of meeting the same heat-supply demand, the application of phasechange energy storage floor with strip structure is more economic and practical. When water supply temperature varies from 50 ℃ to 55 ℃, the average surface temperature of phase-change energy storage floor with strip structure reaches 25 ℃ to 29℃ meeting the requirement for human thermal comfortableness.
