Question
A room window measure (3 m?) constructed of glass with overall heat
transfer coefficient of (4 W/m². °C). The inside design condition of room is
( 22 °C dbt and 50% RH) while the outside temp equals -7 °C.
Determine;
a) The inside glass surface temp
b) Will moister condense on this window
c) Select different glass type to prevent the vapoure condense over glass
( try to use two layers of glass with inside air gap (homemade) heat transfer
coefficient for 6 mm at still layer (between two glass h=5.8 W/m2. °C))
