Abstract:

To analyze the whole performance of the airconditioning system containing different domains, the models of serial port communication and airconditioning are established based on the multidomain unified modeling language Modelica, the airconditioning hardware in the loop(HIL) simulation system is created by connecting and airconditioning controller and model with the serial port communication model and the signal process circuitry, and the result of simulation shows the effectiveness of the system.The HIL simulation system of airconditioning provides a new method of HIL simulation for multidomain systems, which improves the efficiency of production design and reduces the cost evidently.
