传统Trombe墙功能单一，为拓展Trombe墙功能，本文提出一种新型零能耗室内空气净化型Trombe墙系统，结合了太阳能供暖技术和太阳能驱动热催化氧化技术，能同时实现采暖和空气净化。催化剂MnOx-CeO2在太阳能全光谱波段展现出优异的光热转换能力。以甲醛气体为模型污染物，搭建了空气净化型Trombe墙系统性能检测平台，进行了全天性的实验，探究了空气净化型Trombe墙系统的空气集热性能和甲醛降解性能。实验结果表明：以合肥地区为例，空气净化型Trombe墙系统具有优异的空气集热性能和空气净化性能。在全天平均辐照强度为380 W/m2的条件下，空气瞬时集热效率基本在0.1 ~ 0.4之间，甲醛瞬时转化率基本在0.3 ~ 0.6之间；系统的全天空气集热效率为0.21，系统产生的总干净空气量为284 m3/(m2?d)，有较好的应用前景。

To improve the current status of single-function in conventional Trombe wall, this paper proposes a novel zero-energy air purification-type Trombe wall system combining solar air heating technology with solar driven thermal catalytic technology, which can realize air heating and air purification at once. The catalysts MnOx-CeO2 exhibits strong absorption and photothermal conversion performance in whole region of solar spectrum. We built experimental testing platform of air purification-type Trombe wall system using formaldehyde gas as model pollutant. A full-day experiment was conducted to investigate the air heating performance and formaldehyde degradation performance. Results showed that the air purification-type Trombe wall had excellent performance of space heating and air purification and huge potential in the field of energy and environment in Hefei. The instantaneous air heating ef?ciency and formaldehyde degradation ef?ciency were in the range of 0.1 ~ 0.4 and 0.3 ~ 0.6, respectively. The daily air heating ef?ciency was 0.21 and the daily generation of fresh air was 284 m3/(m2?d). This system presents a very good application perspective.
