摘要：

In order to improve the utilization of solar energy in buildings, a new system combining an active-passive ventilation wall with phase change material (PCM) and solar concentrators was proposed, and a two-dimensional unsteady numerical heat transfer model of the proposed wall was established and validated using data collected from field measurement. Using this model, influencing factors, namely, velocity and inlet temperature of air, thickness and length of air tunnel, have been identified to have influence on its thermal performance. Then optimum operational conditions have also been identified to guide the optimal design of the proposed wall and the application of solar energy in buildings. (C) 2016 Published by Elsevier Ltd.
