Abstract

In this paper, double glazing air flow window with integrated blinds (IBAFW) numerically is investigated and the only winter indoor mode is considered for further assessments. To validate the CFD model, the results are compared with the experimental data found in the literature. For the thermal performance evaluation, total heat gain (qgain) which represents the heat gained by ventilation (qadv)and heat gained by the back glass (qbg) was considered. As a part of the study, effect of the structural parameters such as tilt angle of blinds, gap size and the areas of inlet and outlet vents on the thermal performance of IBAFW were studied. The results showed that by changing the blinds tilt angle from 30° to 60°, total heat gain increased approximately 132–146% in different solar radiation ranges. It is also concluded that increasing the gap size increased the total heat gain approximately 106%. However, the increase of outlet vent area effected reversely and resulted in decreasing the thermal efficiency by 127%.
