Specific Applications

1. Condensers and Evaporators

• Condensers: Copper pipes are used in condensers, which are critical components of air conditioning and refrigeration systems. They cool the gaseous refrigerant, condensing it into a liquid. The high thermal conductivity of copper pipes enhances the heat exchange efficiency of condensers.

• Evaporators: In evaporators, liquid refrigerant absorbs heat and evaporates into gas within copper pipes. The thermal conductivity of copper ensures rapid heat transfer, improving the cooling effect.

2. Connecting Pipes

• Refrigerant Lines: Copper pipes connect various components of air conditioning and refrigeration systems, transporting refrigerant. Their corrosion resistance and pressure handling capacity allow for long-term stable operation.

• Liquid Lines: Used for conveying liquid refrigerant, copper pipes’ sealing performance and strength ensure system safety and efficiency.

3. Distributors

• In complex refrigeration and air conditioning systems, copper pipes are used in refrigerant distributors to ensure even distribution of refrigerant to various components.

4. Heat Exchangers

• Plate and Shell-and-Tube Heat Exchangers: Copper pipes act as primary heat exchange elements, utilizing their thermal conductivity to achieve efficient heat exchange and enhance overall system performance.

5. Internal Connections in Refrigeration Equipment

• Cold Storage and Refrigerators: Copper pipes are used in the refrigerant circulation systems inside cold storage and refrigerators, ensuring stable and efficient operation in low-temperature environments.

• Air Conditioning Units: Inside air conditioning units, copper pipes connect key components like compressors, condensers, expansion valves, and evaporators, ensuring smooth operation of the refrigeration cycle.
