3. Type Of Condenser Coil
AC units work on the basis of compression, condensation, and evaporation. This involves moving of the refrigerant gas inside coils in gaseous as well as liquid forms. So lets differentiate between copper and aluminum
Heat transfer
Copper has a higher heat transfer coefficient than aluminum. Hence, it proves to be a better heat exchanger than aluminum
Cost factor
Aluminum is cheaper than copper. Therefore AC units with aluminum coils are cheaper.
Strength
Now, copper is undoubtedly stronger than aluminum. Cooper coils have the reputation of lasting much longer than aluminum coils. They need fewer repairs as well.
Maintenance
Copper coils are easier to maintain whereas you need to keep the aluminum coils in heavy-duty cabinets thereby making them difficult to maintain.
Corrosion
The AC works in a damp environment at all times. Hence, there is always a danger of corrosion. This corrosion results in the formation of a layer over the coils thereby affecting its conductivity.
People living in humid areas near the sea should be extremely cautious about this aspect. For them different type of coating on condenser are been provided by different brand preventing from salt and Rust.
Hence, these coils are a good option for ACs working in coastal regions.
