Effect of indoor shading and heater configurations on the surface temperature performance of a sealed double-glazed window

The inside surface temperature behavior of a window in cold weather affects the comfort of the building occupants and determines the resistance of the window to condensation. In windows containing sealed double-glazing units, the surface temperature behavior of the inner pane also affects its resistance to thermal breakage. The surface temperature performance of a sealed double-glazed window is affected by the design of the sealed unit itself and of the window frame. It is also affected by factors external to the window, such as the room heater configuration and the arrangement of the indoor shading device. The effects of these last two factors on the surface temperature performance of a sealed double-glazed window were investigated in laboratory tests and are herein reported.La temp\ue9rature de la surface int\ue9rieure d'une fen\ueatre par temps froid influence le confort des occupants de l'\ue9difice et d\ue9termine la r\ue9sistance de la fen\ueatre \ue0 la condensation. Dans le cas de fen\ueatres comportant des \ue9l\ue9ments scell\ue9s \ue0 double vitrage, la temp\ue9rature superficielle du panneau int\ue9 rieur influence \ue9galement la r\ue9sistance de celui-ci \ue0 la rupture thermique. La temp\ue9rature superficielle d'une fen\uea tre scell\ue9e \ue0 double vitrage d\ue9pend de la conception de l'\ue9l\ue9 ment scell\ue9 et du cadre de la fen\ueatre, aussi bien que d' autres facteurs comme la configuration du chauffage des locaux et la distribution des dispositifs antisolaires int\ue9 rieurs. On pr\ue9sente les r\ue9sultats d'essais en laboratoire quant aux effets de ces deux derniers facteurs sur la temp\ue9 rature superficielle d'une fen\ueatre scell\ue9e \ue0 double vitrage.Peer reviewed: NoNRC publication: Ye
