Industry knowledge
Air conditioning copper pipes, also known as HVAC copper pipes, are essential components used in air conditioning and refrigeration systems for the transfer of refrigerants and coolants. These pipes are made from high-quality copper material, offering numerous advantages for HVAC applications. 
Air conditioning copper pipes Uses in Air Conditioning Systems and HVAC systems
Refrigerant Lines: Copper pipes serve as refrigerant lines that transport the refrigerant between the indoor and outdoor units of the air conditioning system.
Condenser Coils: Copper tubing is often used to construct the condenser coils, which release heat to the external environment during the cooling process.
Evaporator Coils: Inside the air handler or indoor unit, copper pipes are used as evaporator coils, absorbing heat from the indoor air and cooling it.
Expansion Valve Connections: Copper pipes are connected to the expansion valve, regulating the flow and pressure of the refrigerant.
Liquid and Suction Lines: Copper pipes are employed as liquid and suction lines, ensuring the smooth circulation of refrigerant throughout the HVAC system.
Interconnecting Tubes: Copper pipes are used to interconnect various components within the HVAC system, providing a sealed and efficient refrigerant flow path.
Mini-Split Systems: Copper pipes are commonly utilized in mini-split air conditioning systems due to their flexibility and ease of installation.
