Using Simulink

Some Things to Try

Here are several things to try to see how the model responds to different parameters:

• Each Scope block contains one or more signal display areas and controls that enable you to select the range of the signal displayed, zoom in on a portion of the signal, and perform other useful tasks. The horizontal axis represents time and the vertical axis represents the signal value. For more information about the Scope block, see Scope.
• The Constant block labeled Set Point (at the top left of the model) sets the desired internal temperature. Open this block and reset the value to 80 degrees. See how the indoor temperature and heating costs change. Also, adjust the outside temperature (the Avg Outdoor Temp block) and see how it affects the simulation.
• Adjust the daily temperature variation by opening the Sine Wave block labeled Daily Temp Variation and changing the Amplitude parameter.
