Özet

It is inevitable that the use of energy resources will increase with the increasing human population. In particular, the negative impact of fossil fuel-based energy sources on the environment is indisputably bad. Although the interest in renewable and clean energy has increased in recent years, the incredible increase in energy needs is at an unmet level. Therefore, the use of high-efficiency technological tools and minimizing energy consumption have gained importance. People are in closed environments for long periods of time in their daily lives. It is important for comfort to keep indoor environments warm in winter and at a certain temperature in summer. In this case, building insulation, heating and cooling loads gain importance for energy consumption in order to minimize energy consumption. This study focuses on double glazing applications to minimize energy losses from windows used in indoor environments. The effect of air, argon and krypton gases placed between two 4 mm glasses on heat transfer is evaluated. In addition, the effect of changing the distance between the double glazing between 12-24 mm is given. The study is carried out in continuous conditions with a 2D CFD model. The temperature distribution in the system is examined by keeping the outdoor temperature constant at 5°C and the indoor temperature at 25°C. When the heat transfer of the window is compared for the 3 gases, it is seen that the krypton provides the best insulation and the heat transfer coefficient is around 0.9 W/m2K. In addition, it is understood that the best insulation is obtained for Argon and Krypton when the amount of gas space between the double glazing is 20 mm. It is understood that the insulation value increases as the thickness increases for air. According to these results, fluid movement is an important criterion for heat transfer, as is the thickness between the double glazing.
