2.2 Copper Condenser Coils

Copper has been a traditional choice for condenser coils in air conditioning systems for many years. Copper is known for its excellent thermal conductivity, which means it can efficiently transfer heat. Copper condenser coils typically consist of copper tubing with aluminum fins or louvers to enhance heat transfer.

2.3 Aluminium Condenser Coils

Aluminum is an alternative material used for condenser coils, especially in modern air conditioning units. Aluminum is lightweight and cost-effective compared to copper. Aluminum condenser coils also consist of aluminum tubing with aluminum fins.
