The CFD Simulation Method of Optimizing the Shape to Improve the Air Conditioning Outlet Performance

Zhao Huifang Yang Li Peng jing Duan Dalu

Abstract：With the increasingly fierce competition in the automotive industry， air conditioning systems have gradually gained attention. A better air conditioning system can improve a more comfortable driving environment for the passenger compartment， thereby increasing the competitiveness of the product in the same industry. In the air conditioning system， air ducts and air outlets are important components， and their performance directly affects the ambient temperature and human comfort in the passenger compartment. Taking a SGMW model as an example， this paper simulates the speed field of the air conditioning system through STAR-CCM+ software， analyzes the influence of the air duct and air outlet shape on the air blowing performance of the air conditioner， and improves the air blowing performance by optimizing the air duct and air outlet shape.
