摘　　要：为实现太阳能有序利用,提高太阳能利用效率,提出一种具有空气净化、热电发电、采暖通风等多功能的新型光催化热电Trombe墙。研究了在冬季供暖模式下,通过系统的发电、净化空气、供暖来减少建筑的能源负荷,探讨不同太阳辐射强度、不同流道高度和宽度对系统的性能影响并进行分析。结果表明:随着太阳辐射强度的增大,系统的总效率逐渐增大;随着流道高度的增大,系统的总效率逐渐减小;随着流道宽度的增大,系统的总效率逐渐增大;综合各条件,在太阳辐射强度为800W·m^(-2)、流道高度为1m、流道宽度为0.06m时,本系统的总效率达到最大值为33.92%。本研究将对建筑墙体性能提升和污染物净化提供了理论和技术基础。In order to realize the orderly utilization of solar energy and improve the utilization efficiency of solar energy,a novel photocatalytic thermoelectric Trombe wall with air purification,thermoelectric power generation,heating and ventilation was proposed.In this paper,the energy load of the building can be reduced through the system's power generation,air purification and heating under the winter heating mode.The influence of different solar radiation intensity and different flow channel height and width on the system performance is discussed and analyzed.The results show that with the increase of solar radiation intensity,the total efficiency of the system increases gradually.With the increase of the height of the flow channel,the total efficiency of the system decreases gradually.With the increase of channel width,the total efficiency of the system increases gradually.When the solar radiation intensity is 800 W·m^(-2),the channel height is 1 m,and the channel width is 0.06 m,the maximum efficiency of the system is 33.92%.This study will provide a theoretical and technical basis for building wall performance improvement and pollutant purification.
