Air Conditioning Heat Exchanger Intelligent Production Line: Design Methodologies and Applications

As a key component in modern building environmental control systems, the production quality and performance of multi-split central air conditioning systems directly influence the comfort, energy efficiency, and operational stability of buildings. However, the current manufacturing process primarily relies on a combination of traditional manual labor and automated equipment, resulting in low efficiency, high energy consumption, and limited automation. This paper first presents an optimized design for an intelligent manufacturing production line for multi-split central air conditioning heat exchangers to address these issues. It details the design of key systems for the intelligent production line and ensures continuous production and processing. Additionally, the paper analyzes the production process of the intelligent manufacturing line, with particular emphasis on the mechanism of the heat exchanger tube expansion process. Furthermore, it designs the fixture structure of the transfer robot for each process in the production line and discusses the principles of workpiece positioning and clamping. Utilizing technologies such as sensor networks, PLC, and industrial Ethernet, the system completes the closed-loop process of perception, transmission, analysis, decision-making, and execution within the production line, enabling transparency, fault predictability, and automated management. The results show that the intelligent assembly production line has significantly improved the assembly efficiency, achieving a 300% increase in the daily production capacity of a single line. While enabling the continuous and intelligent production of multi-split central air conditioning heat exchangers.
