Multi-Domain Modeling and Simulation of Automotive Air Conditioning System Based On Modelica

摘要

The automotive air conditioning (AC) systems are complex systems where two-phase flow, pneumatic, mechanical and electrical components are coupled. Such systems coupled with various physical domains have great influence on comfort and dynamic performance of the vehicle, such as cooling performance, driveability, fuel economy, etc. This paper presents a detailed model of AC system, including the condenser, evaporator, compressor, expansion device, etc. The simulation was carried out to study the performance of the AC systems, and the effect on the vehicle performance was studied.
