摘要
以可对比热箱为实验平台,构建相变蓄热型光伏集热(PV-PCM-Trombe)墙体实验系统。通过冬季工况测试,实验分析该系统的光电性能和对建筑热环境的影响等特征。研究结果表明:实验间气温始终高于对比间气温和环境温度,且日平均环境温度越高,实验间与对比间和环境温度的温差也越大,表明本系统可在冬季高效利用太阳能很好实现地建筑被动采暖;相变板在白天吸收太阳能蓄热,可使房间在冬季夜间维持更长时间的舒适温度;实验期间系统的平均光电效率约为13.71%,系统工作时其光电效率与开路电压存在强关联特征。
Taking the comparable hot box as the experimental platform,a photovoltaic Trombe wall experimental system combined with phase change materials(PV-PCM-Trombe)was constructed.Its building thermal environment and photoelectric performance were analyzed through the winter working test.The main research results are as follows:the temperature in the experimental room is always higher than that in the comparison room and the ambient temperature,and the higher the average daily ambient temperature,the greater the temperature difference comes,indicating that the system can efficiently use solar energy to achieve good passive heating effect in buildings in winter;phase change panels absorb solar energy during the day to store heat,which can keep the room warm for a longer time in the winter night.During the experiment,the average photoelectric efficiency of the system is about 13.71%,and there is a strong correlation between the photoelectric efficiency and the open circuit voltage.
