Vrcooler can offer copper air conditioner coil and aluminum air conditioner coil. The following information is for your reference.
The difference between aluminum and copper:
1) heat transfer characteristics:
As the heat transfer occurs, it is very important that the metal has good heat transfer characteristics in the coil. The heat transfer coefficient of copper is higher than that of aluminum. This means that copper is a better heat exchanger than aluminum.
2) cost and flexibility (flexible quality):
Copper is more expensive than aluminum, which increases the cost of manufacturing air conditioners, thereby increasing the price of air conditioners. In order to reduce the unit cost of manufacturing AC, aluminum has become the manufacturer's favorite choice.
Another factor to consider is flexibility. Compared with copper, aluminum has better ability to bend into desired shapes. Therefore, in order to manufacture coils of the same size and shape, it takes about three times as much copper to make the process more expensive.
However, in order to reduce the cost of AC copper coils, more and more copper rings are becoming thinner.
3) strength and reliability:
Copper is easier to repair than aluminum. Many times, when the aluminum coil is damaged, it needs to be replaced. The coils made of copper are much stronger than aluminum. So they are durable.
4) easy to maintain:
Since condenser coils are placed in units normally outside the house, it is exposed to harsh climates and dust, which requires regular cleaning in order to operate better. Having said that, copper rings are easy to clean and maintain because they are durable. Although the aluminum ring is not strong, it needs to be stored in heavy cabinets to prevent damage. This makes them difficult to clean and maintain.
Corrosion plays a very important role in determining the service life of air conditioners. Corrosion can damage the coil, hinder the heat transfer process, and cause leakage. Therefore, it is important to protect the coil from corrosion. In humid climates, people who live near coastal and salt water bodies do more damage because of higher air moisture content in these areas.
