초록

The aim of this study is to compare the insulation performance of each curtain wall system applying the conventional rectangular pipe frame and the truss-shaped insulation frame that reduces the thermal bridging effect of the conventional frame. The insulation performance of each system was evaluated by performing a three-dimensional steady state heat transfer simulation reflecting the actual installation conditions. The results show that the heat losses of the conventional and alternative systems are 33.06 W and 21.12 W, respectively, and the effective U-factors are 0.264 W/㎡K and 0.169 W/㎡K, respectively. The effective U-factor of the conventional system is significantly higher than the design U-factor, indicating that the heat loss due to the thermal bridge is large. The effective U-factor of the alternative system is reduced by 36% compared to the conventional system, which significantly reduces the heat loss.
In addition, the lowest indoor surface temperature and temperature difference ratio of the alternative system increases by 0.5℃ and decreases by 0.02, respectively, compared to the conventional system, which reduces the risk of condensation.
