Abstract：As a core and critical process in air conditioner manufacturing,the refrigerant charging process is widely applied in the air conditioning industry.However,the absence of corresponding entity modeling in digital simulation has hindered the effective simulation of air conditioner production lines.Utilizes the Flexsim simulation platform to conduct secondary development for modeling process equipment,production lines,kinematic mechanisms,and task allocation logic,thereby realizing full production functionality.By integrating virtual reality(VR)display technology,a dedicated simulation platform for the charging process of air conditioner production lines was developed.An immersive virtual scene and digital twin model were established,with animations implemented through Flexsim coding.By embedding production processes into the simulation system,a novel simulation paradigm featuring"virtual experience combined with simulation calculation"was created to pre-evaluate whether production line capacity meets design standards.This research lays a foundation for accurately predicting production capacity and optimizing simulation results in practical production planning and line transformation,thus expanding the application scope of digital simulation technology in the air conditioning manufacturing sector.
