摘　　要：文中设计、加工了一种热风式相变蓄热板,布置在建筑墙体内侧,应用于建筑采暖系统中。实验测试和分析了基于相变蓄热板的模型房间换热特性,在TRNSYS软件中搭建相变蓄热房间的动态热模型,模拟得到相变蓄热房间热特性的变化规律。结果表明,安装有相变蓄热系统的房间平均温度高出普通房间4~5℃,说明该相变蓄热系统可以提高房间温度,改善房间的热舒适性,建立的相变蓄热系统动态热特性模型能较好地预测温度变化过程,为太阳能热风式相变蓄热建筑设计提供了参考。In this study,a phase change thermal storage plate,heated by hot air,was designed.It could be mounted on the internal wall of the building and applied in the building heating system.The thermal characteristics of the model room assisted by the phase change thermal storage system was experimentally studied and compared with that of ordinary room.The TRNSYS model of the phase change thermal storage building was employed to simulate the transient thermal characteristics.The measured and simulated results show that the temperature of the room assisted by the thermal storage system increased from 4℃~5℃ compared with the ordinary room,suggesting that the proposed system can improve the thermal comfort of the room.In addition,the TRNSYS model of the phase change thermal storage building can precisely forecast the transient thermal characteristics.
