Type C air conditioning hose: an innovative choice that redefines industry standards

In the field of industry and heating, ventilation and air conditioning (HVAC), hoses are key connection components, and their performance directly affects the efficiency and safety of the system. Type C air conditioning hoses are gradually becoming the focus of the industry due to their unique design and material advantages. However, many users still lack a clear understanding of the differences between them and other common hoses.
Material innovation: a double breakthrough in pressure resistance and temperature resistance
Traditional air conditioning hoses (such as Type A or Type B) mostly use a single-layer rubber structure. Although the cost is low, they are prone to aging and cracking under extreme pressure or temperature fluctuations. Type C air conditioning hoses use a multi-layer composite process: the inner layer is fluororubber (FKM) or hydrogenated nitrile rubber (HNBR), which has excellent chemical corrosion resistance; the middle layer is woven with high-strength synthetic fibers to enhance pressure resistance; the outer layer is covered with chloroprene rubber (CR) with excellent weather resistance to resist ultraviolet and ozone erosion. This "sandwich structure" enables it to maintain stable performance in an environment of -40°C to 150°C, far exceeding the tolerance range of -20°C to 100°C of ordinary hoses.
Structural optimization: balance between lightness and flexibility
To improve the pressure bearing capacity, traditional hoses often add metal wire layers or thicken the tube wall, resulting in increased weight and limited bending radius. Type C hoses use innovative fiber braiding technology to reduce weight by 30% at the same pressure level (such as 3.5MPa) while achieving a smaller bending radius (up to 4 times the tube diameter). This feature makes it easier to install in small spaces or dynamic equipment (such as mobile air-conditioning units), reducing the risk of fatigue damage caused by repeated bending.
Compatibility and life: reduce comprehensive operation and maintenance costs
Due to material limitations, ordinary hoses are often less compatible with new environmentally friendly refrigerants (such as R32 and R454B), and long-term use may cause swelling of the inner wall or refrigerant leakage. Type C hoses can be adapted to a variety of refrigerant media including POE oil through customized inner layer material formulas to ensure long-term and stable operation of the system. According to third-party laboratory data, the average life of Type C hoses in continuous high-pressure tests reaches 120,000 cycles, which is more than 50% longer than traditional hoses. For commercial air conditioning systems that need to operate 24/7, this means lower downtime maintenance costs and longer replacement cycles.
Application scenarios: Precisely matching industry needs
The advantages of Type C air conditioning hoses are particularly prominent in specific scenarios:
Data center precision air conditioning: Need to deal with high-frequency refrigerant circulation and constant high pressure, Type C's fatigue resistance can ensure zero unexpected interruption of the system.
Cold chain logistics vehicles: In extreme temperature difference environments, its low temperature resistance can avoid the risk of hose embrittlement.
Industrial heat pump system: High temperature resistance and chemical resistance are compatible with complex media in waste heat recovery.
Type C air conditioning hoses are not simply "upgraded versions", but a new solution for the stringent needs of modern HVAC systems. Its technological breakthroughs are not only reflected in a single performance parameter, but also through the collaborative innovation of materials, structures and scene adaptation, providing users with long-term and reliable value returns. Choosing Type C means choosing to achieve a double leap in system efficiency and safety at a lower full life cycle cost.
