Copper tube or aluminum tube is used in commercial refrigeration system?

For commercial freezer, use copper tube is better than aluminum, but some supplier will use aluminum pipe instead of copper because of cost. But green&health refrigeration equipment company use copper tube for all machine to ensure supermarket freezer has a better performance. But below list some different points between copper pipe and aluminum pipe for reference.

Advantages of copper pipes:

• High thermal conductivity: Copper has a very high thermal conductivity, enabling rapid heat transfer and more effective refrigeration.
• Good corrosion resistance: Copper is not easily oxidized or corroded, providing good corrosion resistance and ensuring a long service life for refrigeration pipes.
• Excellent weld ability: Copper pipes are easy to process and connect, making them highly suitable for creating complex pipeline structures within freezers.

In supermarket freezers, copper pipes are often used in high-end models or scenarios requiring higher refrigeration efficiency and durability. For instance, oxygen-free copper pipes, which have undergone deoxidization treatment, boast low internal impurity content, superior thermal conductivity, and excellent corrosion resistance, thus widely applied in refrigeration equipment and air-conditioning fields.

Advantages of aluminum pipes:

• Lightweight: Compared to copper pipes, aluminum pipes have a lower density and lighter weight, helping reduce the overall weight of freezers.

• Easy processing: Aluminum pipes exhibit good processing properties, allowing for the creation of intricate refrigeration pipeline structures.

• Good strength: Although aluminum's strength is slightly inferior to copper, it is sufficient to withstand various pressure changes in the refrigeration system of freezers.
