Performance Simulation and Study Analysis of The Vehicle Air Conditioning System

摘要

In this paper, it is established the model of air-conditioning system and a simplified model of cooling system in the vehicle. That model is based on the test data. One-dimensional model has been corrected by the three-dimensional calculation results. Therefore, the one-dimensional model also reflects the impact of cabin air return. The results show that the coolant temperature affect on the performance of air conditioning is very small. But the ambient temperature affect on the performance of air conditioning is significant.
