摘　　要：基于能量和质量平衡原理,建立光伏光催化型Trombe墙性能分析和评价的非稳态集总模型.研究了在冬季运行模式下,不同的室内外环境温度对系统性能和功能的影响.结果表明:文中建立的性能分析和评价模型是可行的;随着室外环境温度的降低和室内温度的升高,光伏光催化型Trombe墙的热效率、日产生的净化空气量和总效率均下降,其中最大总效率从55.3%减小到43.4%,而发电量和电效率变化较小.室内或室外温度的上升都会使光伏光催化型Trombe墙的空气出口温度上升,甲醛降解效率提高.在10:00之前或16:00之后,太阳辐射强度较低时,存在光伏光催化型Trombe墙功能失效情况;室外环境温度越低,室内温度越高,光伏光催化型Trombe墙的有效运行时间越短.Based on energy and mass balances,an unsteady lumped model for the performance analysis and evaluation of PV-PC-Trombe wall was established to study the influences of different indoor and outdoor environmental temperatures on the system performance and functionality in winter operating mode.The results show that the performance analysis and evaluation model established in this paper is feasible.As the outdoor temperature decreases or the indoor temperature increases,the thermal efficiency,the daily clean air volume and the total system efficiency of the PV-PC-Trombe wall all go down,and the maximum total efficiency decreases from 55.3%to 43.4%,while the change in power generation and electrical efficiency is little.The increasing of indoor or outdoor temperature will increase the air outlet temperature and formaldehyde degradation efficiency of the PV-PC-Trombe wall.Before 10:00 or after 16:00,when the solar radiation intensity is low,there is a function failure of the PV-PC-Trombe wall;the lower the outdoor ambient temperature and the higher the indoor temperature,the shorter the effective operating time of the PV-PC-Trombe wall.
