太阳能热催化技术利用太阳全光谱产生集热和降解甲醛,太阳能光热复合催化技术是一种可以同时利用光和热产生热量并降解甲醛的高效技术.分别将热催化、光热复合催化百叶技术应用到Trombe墙系统,实现采暖的同时,能够利用太阳光降解室内气态污染物.建立热催化、光热复合催化百叶Trombe墙传热传质模型并进行实验验证,基于模型探究热催化百叶Trombe墙和光热复合催化百叶Trombe墙在南京和北京冬至日(9:00-17:00)气象参数下百叶全天最佳调控策略.结果表明,建立的传热传质模型预测与实验数据符合度较高.同一百叶Trombe墙系统,不同地区的最佳百叶角度不同;对于热催化百叶Trombe墙,南京全天最佳百叶角度下,产生的热量和干净空气量分别为5.6 MJ/d、196.7 m3/d,北京分别为4.6 MJ/d、167.9 m3/d;对于光热复合催化百叶Trombe墙,南京全天最佳百叶角度下,产生的热量和干净空气量分别为6.7 MJ/d、205.6 m3/d,北京分别为5.4 MJ/d、174.8 m3/d;在全天最佳百叶角度调控策略下,其南京冬至日产生的热量和干净空气量分别为热催化百叶 Trombe 墙系统的1.20 倍和1.05倍;系统位于北京时,分别为热催化百叶Trombe墙系统的1.17倍和1.04倍.
Performance Analysis of the Photo-Thermal Composite Catalytic Trombe Wall and the Angle Control Strategy of Blinds
Solar thermal catalytic technology can use the sun's full spectrum to generate heat collection and purify formaldehyde.Photo-thermal composite catalytic technology is a highly efficient technology that can use solar light and heat to generate heat and formaldehyde degradation simultaneously.Thermal catalysis and photo-thermal composite catalytic technology composite blinds were applied to the Trombe wall system,which used sunlight to degrade indoor gaseous pollutants while heating.This paper established the heat and mass transfer model of the Trombe wall with thermal/photo-thermal composite catalytic blinds,and experimental verification was carried out.Based on the model,the optimal control strategy of blinds for the Trombe walls was explored under the meteorological parameters of Nanjing and Beijing winter solstice(9:00-17:00).The results demonstrated excellent agreement between the established heat and mass transfer model predictions and experimental data.Notably,regions require different optimal blind angles for identical Trombe wall systems with blinds.The heat generated and clean air at the best optimal blinds for the Trombe wall with thermal catalytic blinds were 5.6 MJ/d and 196.7 m3/d,respectively.In Beijing,they were 4.6 MJ/d and 167.9 m3/d,respectively.For the Trombe wall with photo-thermal catalytic blinds system,the heat generated and clean air at the best optimal blinds were 6.7 MJ/d and 205.6 m3/d,respectively.In Beijing,they were 5.4 MJ/d and 174.8 m3/d,respectively.Under the optimal louver angle control strategy,the heat and clean air generated in the winter in Nanjing was 1.20 and 1.05 times that of the Trombe wall with photo-thermal catalytic blinds system,and 1.17 and 1.04 times that of the Trombe wall with thermal catalytic blinds system when the system was located in Beijing.
