Study of hybrid natural ventilation using a combination of turbine ventilator and solar chimney

Solar chimney is a common passive natural ventilation system. There is a small potential value when solar chimney is used independently. Therefore, solar chimneys are always applied in the form of integrating configurations. The aim of this study is to investigate the ventilation performance by inte...

Study of hybrid natural ventilation using a combination of turbine ventilator and solar chimney
description Solar chimney is a common passive natural ventilation system. There is a small potential value when solar chimney is used independently. Therefore, solar chimneys are always applied in the form of integrating configurations. The aim of this study is to investigate the ventilation performance by integrating solar chimney and turbine ventilator. A small size solar chimney is proposed that ease its integration with turbine ventilator. The performance of solar chimney is studied experimentally by heating the solar chimney at constant heat flux. It is found that higher inclination angle and larger air gap depth is performing better. However, the performance start deteriorating after optimum value of inclination angle and air gap depth. Although no specific relationship can be found for inlet and outlet aperture area, but the inlet aperture area is recommended to be at least double the size of outlet aperture area. The integrated system is studied experimentally by heating the solar chimney under constant heat flux and/or by rotating the turbine ventilator at constant rotational speed. The results demonstrate that the ventilation performance of the solar chimney with rotating turbine ventilator is performing the best. The proposed solar chimney also shows the capability to encounter the flow reversal effect as the absence of wire mesh outperform the presence of wire mesh. All those results will be useful in the future solar chimney development either for designation or prediction to achieve the ventilation requirement.
