光伏建筑一体化（BIPV）夏季热通道热工性能的实验研究

摘要

对株洲市的一栋光伏建筑一体化（BIPV）建筑的流通通道进行热工参数的实验研究，测试包括了通道内空气温度、速度，太阳辐射强度以及环境温度等参数。确立了通道内温度场、光伏背板温度以及内外墙温度随室外环境参数的变化趋势，以及温度场之间的相互关系，明确了带通道的光伏幕墙的传热过程。分析可知上午的通风效果较好，晴天一天内通道内空气温度最高可达45℃，背板温度最高可达54℃。通过比较通道内外空气温度以及外墙温度的关系，定性的了解了通道启闭的时间，从而到达节能的目的。%The experimental research on thermodynamic parameter of the BIPV channel in Zhuzhou was did. Air temperature, velocity in channel, solar radiation and ambient temperature were tested. Temperature field change of air, PV backplane and exterior wal based on the environment parameter were determined as wel as their changing relationship. The process of heat transfer in the curtain wal with thermal channel was also clear. The analysis of the temperature filed indicates a better performance of natural ventilation in the morning. The maximum air temperature in the channel was 45℃and the maximum PV channel temperature was 54 ℃ .We know the time to open the channel in order to save energy by analyzing the temperature relationship between air temperature in and out the channel and the external wal .
