Automotive air conditioning pipes are critical components within the vehicle's climate control system, serving to transport refrigerant throughout the cooling cycle. These conduits are typically constructed from multi-layered composite materials, comprising an inner rubber tube, a reinforcement layer, and a protective outer layer, ensuring safe and reliable operation under high-pressure and elevated-temperature conditions. Automotive air conditioning hoses serve as the “arteries” throughout the entire air conditioning system, responsible for conveying refrigerant from the compressor to components such as the condenser, evaporator, and liquid receiver-drier, thereby enabling the vehicle's interior cooling function.

Automotive air conditioning pipes are extensively utilised in the air conditioning systems of various vehicles, primarily serving to connect key system components, including:

• The high-pressure pipe between the compressor and condenser: This high-pressure pipe conveys the high-temperature, high-pressure refrigerant gas from the compressor to the condenser for heat dissipation. During this process, the refrigerant transitions from a gaseous to a liquid state, requiring the high-pressure pipe to withstand significant pressure and temperature fluctuations.
• The low-pressure line between the condenser and evaporator: This line conveys the cooled, liquefied refrigerant from the condenser to the evaporator. Within the evaporator, the refrigerant absorbs heat and vaporises, thereby cooling the cabin air. Although operating at relatively lower pressure and temperature, the low-pressure line must maintain excellent sealing integrity to prevent refrigerant leakage.
• Suction line between evaporator and compressor: The suction line returns the low-temperature, low-pressure refrigerant gas—evaporated after absorbing heat in the evaporator—back to the compressor, completing the refrigeration cycle. Typically located near the evaporator, the suction line experiences lower temperatures and requires protection against condensation and corrosion.
• Connections to auxiliary components: Automotive refrigerant lines also link auxiliary components such as the receiver-drier, expansion valve, or thermostatic expansion valve, ensuring unimpeded refrigerant flow throughout the system.

Within the vehicle's air conditioning system, automotive refrigerant lines undertake the critical task of connecting and conveying refrigerant. Their performance directly impacts the cooling efficiency and reliability of the entire air conditioning system.
