| Abstract |
The aim of this study was to verify the effect of condensation prevention according to the location of low-E coating on double-glazed windows. The test conditions and measurement locations were selected according to the “Design standard for preventing condensation in apartment buildings.” Testing was performed according to the test method of KS F 2295. The cases were selected according to the type of insulating spacer and the location of the low-E coating. The temperature difference ratio (TDR) was analyzed by measuring the inside and outside surface temperatures of the windows and the air temperature of the air cavity. As a result of verifying the condensation prevention performance through a mock-up test, the condensation prevention performance of Case 6, which applied the outside low-E and the insulating spacer (TPS) was the best in region II (-15℃). Changing the low-E coating location from the inside to the outside of the window was effective in improving the condensation prevention performance. In the case of applying outside low-E and an insulating spacer, the air temperature of the air cavity and the surface temperature of the glass edge were increased, improving the condensation prevention performance and reducing the cost of the windows and doors. |
