Study on Performance of Insulating Glass with Built-in Louvers in Buildings

This paper mainly studies the shading problem of shutters in typical rooms of buildings in winter. In order to further study the performance of the built-in louver insulating glass, the built-in louver insulating glass was simulated under the standard operating conditions and throughout the year through software such as THERM and Windows, and the key parameters such as total heat transfer coefficient, solar transmittance, and solar heat gain coefficient were obtained. The heat transfer coefficients of the built-in louver insulating glass when the louvers are placed at 0°, 45°, 90°, -45° and without louvers are 3 W/m2•K, 2.75 W/m2•K, 2.38 W/m2•, respectively. K, 2.55 W/m2•K and 2.66 W/m2•K. The solar transmittance of the built-in louver insulating glass at different angles of the louver is obtained. The maximum value is 0° and no louver, followed by the angles of 45° and -45°. Zero at 90°.
