An active breathing wall to improve indoor environment
An active breathing wall to improve indoor environment
Yue Zhao, Tengfei Zhang, Shugang WangDOI: https://doi.org/10.26868/25222708.2011.1238Abstract: To maintain good indoor air quality, this investigation proposes a prototype of an active breathing wall system, which is composed of a solar radiation absorption board, air heating cavity, porous filtration unit and fan device. The thermo-flow performance of a physical model is measured and compared against the computational fluid dynamics (CFD) modeling. Then an office environment with a breathing wall is simulated by CFD. This study finds different ventilation modes are formed within the room in different seasons. The system generally has good performance to enhance the outdoor air supply rate without causing moisture condensation in the winter. Pages: 429 - 435 Paper:
