Description

The Perfect Insulator block represents a thermal element with perfect insulation and no thermal mass.

You can use this block as an insulation for thermal ports to prevent heat exchange with the environment and to model an adiabatic process. This is not necessary because if you leave a conserving port unconnected, the physical network sets all the Through variables at that port to 0. However, terminator blocks improve diagram readability.

You can also use this block to set the initial temperature at a node.

Variables

To set the priority and initial target values for the block variables prior to simulation, use the Initial Targets section in the block dialog box or Property Inspector. For more information, see Set Priority and Initial Target for Block Variables.

Nominal values provide a way to specify the expected magnitude of a variable in a model. Using system scaling based on nominal values increases the simulation robustness. Nominal values can come from different sources, one of which is the Nominal Values section in the block dialog box or Property Inspector. For more information, see Modify Nominal Values for a Block Variable.

Examples

Building Ventilation

Building Ventilation

Models a ventilation circuit in a building. The air volume inside the building is divided into four zones. The ventilation unit blows cool air into Zone 1 and extracts air from Zone 3. The extracted air can be optionally recycled back into Zone 1. A door in Zone 4 can be opened to vent air out to the atmosphere.
