摘　　要：提出了一种新的相变材料蓄热墙板(PCMSW)与太阳能加热耦合的方式。通过结合TRNSYS的瞬态传热模型,利用FORTRAN语言编译了新模块Type269以与TRNSYS耦合,并结合实验数据研究了PCMSW的热性能。以位于天津的典型办公楼为研究对象,以室内温度为评价指标,结合舒适度,讨论并分析热水流量、熔化温度、PCMSW厚度对室内温度的影响,结合不适度对建筑物热环境进行分析研究。结果表明,增加热水流量、降低PCMSW的熔化温度和厚度可以提高室内温度,随着相变厚度的增加,室内温度和太阳辐射之间的峰值滞后变大。PCMSW能够平衡太阳能供需不匹配,增加太阳能和清洁加热应用的能力。This study proposes a new way that phase change material thermal storage wallboard(PCMSW)coupled with solar heating.By combining the transient heat transfer model of TRNSYS,a new module Type269 was compiled with FORTRAN language to couple with TRNSYS,and the thermal performance of PCMSW was studied with experimental da⁃ta.A typical office building in Tianjin was taken as a research object.The indoor temperature and comfort level were treated as the evaluation criterion to analyze the effects of hot water flow,melting temperature and PCMSW thickness on indoor temperature.It is analyzed in combination with discomfort.The results show that increasing the hot water flow rate and decreasing the melting temperature and thickness of the PCMSW can improve the indoor temperature.As the thick⁃ness of the phase change grows,the peak hysteresis between the indoor temperature and the solar radiation enlarges.PC⁃MSW can balance the mismatch between the supply and demand of solar energy and increase the capacity of solar energy and clean heating applications.
