Explore our state-of-the-art parts and components manufactured for top tier reliability and global HVAC system compatibility.
Ningbo Taojun Refrigeration Equipment Co., Ltd. is located in Xiangshan, Ningbo, a historic and economically dynamic port city. Founded in 1988, our predecessor was the Xiangshan Refrigeration Accessories Factory of Zhejiang University. This foundational link with one of China's top academic institutions instilled a rigorous scientific approach to thermodynamic design and manufacturing early in our history.
For more than three decades, we have continuously scaled our capabilities. Today, Taojun is a comprehensive high-tech enterprise integrating the design, R&D, precision manufacturing, global sales, and after-sales support of refrigeration accessories. Our core product lines include filter driers, check valves, air conditioning valves, condensers, brass and copper accessories, air conditioning cable ties, and other premium system configurations.
In 2021, our commitment to technical excellence earned us the status of a National High-Tech Enterprise. Under our domestic brand "Lingshan" and our global brand "Taojun", we have built an industry reputation for engineering precision and system reliability, serving global HVAC giants such as Haier, Xinfei, Midea, Gree, Whirlpool, Electrolux, and Huarui.
Exploring the metallurgical shifts, international standards, and green directives steering global procurement strategies.
With the global phase-down of hydrofluorocarbons (HFCs), the industry is transitioning to eco-friendly refrigerants like R32 and R290 (propane). These refrigerants work at higher operating pressures, requiring copper pancake coils to feature advanced wall thickness uniformity, enhanced tensile strength, and defect-free structures to prevent hazardous leakage.
Modern HVAC systems prioritize heat transfer efficiency. Copper pancake coils are shifting towards inner-grooved designs, which maximize the internal surface area and create turbulence within the refrigerant flow. This innovation significantly improves overall heat exchange efficiency while reducing refrigerant charge requirements.
Leading factories are integrating automatic continuous extrusion and eddy-current testing systems. This setup eliminates manual brazing joints along structural paths and reduces inner surface residue, which is critical for protecting high-precision digital control systems and variable-frequency compressor valves.
