Numerical Simulation of the Performance of a Solar-induced Ventilation Wall

In order to investigate the operation performance of solar-induced ventilation wall(SICW) and find the influence of various factors on the performance of SIVW,a simple mathematical model was proposed and developed based on the analysis of energy conservation.Steadystate heat transfer equations were set up to determine the boundary temperatures at the surface of the glazing,rear solar heat absorbing wall and air flow in the channel using a thermal resistance network analysis.Based on the model,numerical simulation of the performance of a SIVW was undertaken to explore the effects of the size of the SIVW and outdoor climate parameter on the performance of the SIVW.The results show that the working performance of the SIVW is affected greatly by the size and outdoor climate conditions.The increase of width and height of SIVW,solar radiation and outside temperature can all improve the performance of SIVW.On the contrary,the blindfold increase of air gap between the glazing and solar heat absorbing wall and outdoor wind velocity will reduce the performance of SIVW.As for the air gap,a gap of about 0.1 m is advisable for optimizing the ventilation effect of SIVW for the calculated conditions used in this paper.
