摘要:Through a mock-up test the surface temperature distribution and condensation characteristics were analyzed for a vacuum insulated glass (VIG) window, manufactured through an in-vacuum method, and compared with a double-glazed (DG) window. The outside air temperature was -21.2°C for a VIG window, at which the inside surface condensation begins to occur, given an inside air temperature of 20°C and an inside relative humidity of 50%; thus, given the typical weather conditions for Seoul, a VIG window is not likely to have condensation. The surface temperatures of the VIG window were found to be approximately 4 K–6 K higher than those of the DG window. In the case of the VIG window, the surface temperature of the center of glass is higher than that of the frame, because the vacuum insulated glass (VIG) has a superior insulation performance compared with the frame. However, the surface temperature of the edge of the vacuum insulated glass is lower than that of the frame, by approximately 0.9 K–1.5 K. Thus, to reduce heat loss and improve condensation resistance, measures to reduce heat loss at the glass connection should be established and frames should be utilized that have insulation performance equal to or better than VIG.
