For the windows, choose a double-pane window (two sheets with an insulating gas between them between), and define the thermal resistance network, including: Convection from the room to the window inside surface Conduction through the window Convection from the window outside surface to the outside air Here is a potential diagram for your window design, and the corresponding thermal resistance network. Window Model Double-Pane Inside Window Outside | T6=32C Im h = 35 W/mK hi=25 Ti TU To Rhi Rw Rho The design of the walls must include: Inside surface material (sheetrock, wood paneling, ...) 2x4 pine wood structural joist (3.81 cm x 8.89 cm) spaced with the center line of the beam 18 inches (45.72 cm) apart Insulation between the joist (fiberglass roll, fiberglass blown, foam, ...) Outside surface material (brick, stone, siding, ...) Here is a potential diagram for your window design, and the corresponding thermal resistance network. Wall Model Inside T=210 h = 25 = 4 mK 18" Wall Outside Insolation 2x4- To=32C Jm W ho=354/mik Riza Tu To Rho ZX4 Ti Rui . T, T ame Rwzb If the materials and dimensions are not specified, you are free to choose what you would like for your house. The tables in the textbook have some common building materials to use. You are also welcome to find other materials. Complete the following for the WINDOW: 1. Create a sketch of a 1m x 1m section of the window for your proposed house design, including dimensions and materials to be used. 2. Create a sketch of the thermal resistance network for the window, including convection on the inside and the outside surfaces of the window. Use a convective heat transfer coefficient on the inside wall surface of h; = 25 W/mK and on the outside wall surface of ho = 35 W/mK. 3. Determine the overall thermal resistance of the window (including convection). 4. Calculate the heat transfer rate for an inside air temperature of T; = 21 C and an outside are temperature of To = 32 C. Complete the following for the WALL: 1. Create a sketch of a 1m x 1m section of the wall for your proposed house design, including dimensions and materials to be used. 2. Create a sketch of the thermal resistance network for the wall, including convection on the inside and the outside surfaces of the wall. Use a convective heat transfer coefficient on the inside wall surface of h; = 25 W/mK and on the outside wall surface of ho = 35 W/mK. 3. Determine the overall thermal resistance of the wall (including convection). 4. Calculate the heat transfer rate for an inside air temperature of T; = 21 C and an outside are temperature of T = 32 C.
