The red copper variable-diameter tee specially built for central air conditioning and commercial HVAC systems adopts five-axis linkage CNC precision machining technology to accurately control key parameters such as the flow channel size, port perpendicularity and concentricity of the tee. The dimensional tolerance is strictly controlled within ±0.02mm to ensure perfect matching with the pipeline. Its T-type structure is optimized through fluid dynamics simulation, which can realize precise diversion and confluence of hot and cold medium pipelines, with a flow distribution error ≤3%. The variable-diameter design can flexibly adapt to the connection between main and branch pipelines of different diameters, reducing the number of pipeline reducing joints by 50% and significantly simplifying the pipeline layout. The product uses TP2 red copper with high thermal conductivity, which is as high as 401W/(m·K), much higher than ordinary copper materials, which can accelerate the heat transfer…
