Study on thermal performance of insulating glass window with blind inside

Abstract

In this paper, heat transfer theory is used to analyze the basic heat transfer process of insulating glass windows with blind inside, for which a simple mathematical model is established. By using the calculation software for thermal performance of doors, windows and glass curtain wall, the heat transfer coefficient and shading coefficient (SC) of ordinary hollow blind glass window was calcu-lated. The simulation results showed a certain adjustable range for the heat transfer coefficient and SC of insulating glass windows with blind inside. Through the adjustment, different demands of heat insulation, shading and day lighting can be fulfilled. The feature of excellent thermal performance of insulating glass windows with blind inside can be used to fulfill the energy-saving requirement at the present stage and natural day lighting demand. This study can contribute to improve the thermal performance of building envelope and enhance energy conservation level. © Springer-Verlag Berlin Heidelberg 2014.
