Abstract

This article proposes a year-round purified Trombe wall with ventilation blinds based on solar photo-thermal driven purification that realizes formaldehyde degradation in whole year, space heating in winter and space cooling in summer. The purification blinds are installed in the air channel in traditional Trombe wall, with a photocatalytic layer and thermal catalytic layer on both surfaces, respectively. Firstly, the purification blinds were designed and manufactured. Secondly, based on the verified models, a numerical model of Trombe wall with ventilation blinds considering heat and mass transfer processes was established. Thirdly, the effect of blinds angle on the energy performance was investigated. Finally, the annual optimal operation strategy on blinds angle was investigated. Main results are: (1) The purification performance in summer mode is better than that of in winter mode because of the combination effect of photocatalytic and thermal catalytic purification. (2) The optimal operation angles on purification blinds from January to December are 45°, 45°, 45°, 15°, 30°, 15°, 15°, 15°, 15°, 15°, 0° and 15°, respectively. (3) Applying the annual optimal operation strategy on blinds angle, the total volume of annual generated clean air is 7.12 * 104 m3/m2. The total reduced heating loads for Trombe wall with ventilation blinds in winter seasons are 986 MJ/m2, which is 1.75 times larger than that of in Trombe wall. While based on Trombe wall, Trombe wall with ventilation blinds could save the total reduced cooling loads of 141 and 59.2 MJ/m2 in summer and transition seasons, respectively.
