THE EFFECT OF THE BARRIER DESIGN ON THE HEAT CONDUCTION IN DOUBLE GLASS WINDOWS

In daily life, people spend most of their time indoors. This situation increases the need to keep indoorenvironments warm in winter and cool in summer. This directly increases energy consumption. Since energydependence is dependent on fossil fuels and causes severe environmental pollution, energy consumption canbe significantly reduced with insulation applications to be made in buildings. Windows are responsible forapproximately 40% of the heat transfer in buildings. For this, reducing heat losses through windows cansignificantly reduce energy consumption. This study aims to restrict air movement with barriers in doubleglazedwindows. By preventing the air movement between the double glazing, the natural convection effectswill weaken and decrease the heat transmission coefficient. The 2D CFD model is verified by using ANSYSengineering commercial software and the heat transfer coefficient (Uw) of the insulated glass with air within20 mm is determined as approximately 1.6 W/m2K. Then, the change in the heat transfer coefficient of theinsulating glass is evaluated with differently positioned barriers. It is seen that the barrier placed diagonallyreduces the heat transfer coefficient. It is seen that the heat transfer coefficient of the insulating glass with thebarriers placed in two different ways is 1.4 W/m2K and 1.52 W/m2K, respectively. Similarly, it is understoodthat the thickness of the insulating glass also affects the heat transfer coefficient. This study shows that theheat loss from the windows can be reduced by up to 12.5% by using a barrier.
