Copper pipes are crucial components in air conditioning installations. However, many consumers might not be familiar with the structure, functions, and operational principles of copper pipes. Let's delve into the details in this article by Mytour!
1. Key insights into AC copper pipes
1.1. What is an AC copper pipe?
An AC copper pipe, also known as a gas conduit, is a vital part in air conditioning installations. Therefore, adhering to specific standards during copper pipe installation is essential to ensure stable AC operation, enhance longevity, and conserve energy.
Depending on the AC model, the length of the copper pipe should range from a minimum of 3m to a maximum of 15 - 30m. Inadequately short pipes can cause gas blockages and damage, while excessively long pipes can lead to slow cooling and increased energy consumption.
1.2. Structure
True to its name, copper pipes are crafted from pure copper material. Some variants are made with copper alloy mixed with aluminum. Each copper pipe is equipped with a flare for easy connection to the condenser and evaporator units.
1.3. Role of copper pipes
The primary function of air conditioning copper pipes is to facilitate the circulation of gas from the evaporator to the condenser and vice versa. Therefore, it's crucial to choose copper pipes that are compatible with your air conditioner. Additionally, regular maintenance and cleanliness are essential to uphold the cooling efficiency and durability of the air conditioner.
2. Operational principle of copper pipes
In terms of operational principle, air conditioning copper pipes are connected to the compressor and expansion valve to form a closed loop. Simultaneously, two ventilation fans are installed at the condenser and evaporator units to accelerate the heat transfer process (refer to the illustrative diagram for details)
During this process, the compressor will compress the gas into high pressure. Subsequently, it will push the gas through the condenser to cool it down. Thanks to the ventilation fan, the heat dissipation at the condenser will occur more rapidly, causing the gas to cool gradually and transfer to the expansion valve.
At the expansion valve, the gas will undergo pressure reduction, forming cool air streams transferred to the evaporator and absorbing heat from the environment. With the help of the ventilation fan at the evaporator, this process will happen more swiftly. As a result, users can enjoy cool and refreshing air when using the air conditioner.

3. Classification of copper pipes in the current market
Currently, there are two methods to classify copper pipes based on origin and size. Specifically
3.1. Classification of air conditioning copper pipes based on size
Phi (symbol Ø) is the unit for measuring the outer diameter of water pipes or copper pipes. Based on size criteria, air conditioning copper pipes are classified into various types: Ø6.4, Ø12.7, Ø19.1, Ø9.5, Ø15.9,...
Therefore, for each air conditioner model, there will be corresponding sizes of copper pipes that you can refer to:
- For 1HP capacity air conditioners, use copper pipes with sizes 6mm or 10mm
- For 1.5 HP capacity air conditioners, use 10mm or 12mm copper pipes
- For 2HP capacity air conditioners, use 8mm or 12mm copper pipes
3.2. Classification of copper pipes based on origin
Based on origin, air conditioning copper pipes currently come in various types:
- Vietnamese copper pipes are made from recycled copper, affordable but prone to punctures during transportation
- Korean copper pipes: made from pure copper, known for fast gas conduction and deep cold retention
- Thai copper pipes: made from pure copper, fast gas conduction, excellent cold retention, with durability ranging from 7 to 10 years
- Malaysian copper pipes: made from pure copper material, with durability up to 15 - 20 years
