1 Truck Cooling System
1.1 Summary
This example is to:
?
?
parameters,
?
?
?
get familiar with the basic structure of KULI,
learn how to enter data in the four main General data, Circuits/Air Path, Air side and Simulation
learn how to use the component library to insert an existing component into your cooling system,
learn how to connect the components both in the circuit and on the air side and finally
learn how to start a simulation run and view the results in the output file (*.aus)
In the last section of this chapter we will also take look at how variations in the input data influences the
results of our simulation.
1.2 Introduction
The following steps have to be carried out to create the cooling system file for the example TRUCK.
IconDescription
KULI Program icon
To start the simulation software KULI, click on the program icon. This will bring you to the main window
of the program called System Generation. All input data required to define your cooling system can be
entered here.
