Özet

In the present study, heat transfer structures were investigated for thermal bridges on both intermediate floor beamed wall block and balcony extension intermediate floor beamed wall. Temperature and heat flux contours were obtained for all models in the case of internal and external insulation cases with different insulation thicknesses (Si = 3 cm, 5 cm and 7 cm). Results showed that high heat transfer rates were obtained in the region of heat bridges for all building models. However the heat transfer rate did not decrease on the heat bridge region in the case of internal insulation. The most appropriate insulation model was the external insulation case and it was also obviously determined that heat transfer rate decreased with increments of insulation thickness.
