Through functions such as heat insulation, preventing condensation, and reducing noise transmission, it ensures the efficient operation of air conditioning systems and the comfort of the surrounding environment. It plays an important role in air conditioning systems.

[0003] Existing air conditioning insulation pipes typically use foam or plastic insulation pipes for insulation. However, due to the effects of temperature changes, sunlight, and other factors during long-term use, the insulation pipes will gradually age, become brittle, and leak, affecting their service life and reducing their overall performance. Summary of the Invention

[0021] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0022] Air conditioning insulation pipes are special materials used to wrap air conditioning ducts. Their main function is to prevent excessive heat exchange between the refrigerant or hot / cold water inside the pipes and the external environment during transportation, thereby improving the energy efficiency and operational efficiency of the air conditioning system. Air conditioning insulation pipes play a crucial role in modern air conditioning systems, and their design, material selection, installation, and maintenance directly affect the performance and service life of the air conditioning system.

[0023] Air conditioning insulation pipes come in a variety of materials, commonly including rubber-plastic insulation, polyurethane insulation, fiberglass insulation, and polyethylene insulation. Each material has its unique properties and applications. Rubber-plastic insulation is a closed-cell foam structure material with excellent thermal insulation, waterproofing, sound absorption, and flame retardancy. Its low thermal conductivity effectively prevents heat transfer and moisture penetration, making it one of the most widely used air conditioning insulation materials. Polyurethane insulation, primarily composed of high-performance polyether polyols and polymethyl polyphenyl polyisocyanates, boasts excellent characteristics such as light weight, high strength, thermal and sound insulation, flame retardancy, cold resistance, corrosion resistance, and water resistance. Fiberglass insulation, with its soft and fluffy properties, is suitable for central air conditioning ducts and rigid pipes, but its potential health hazards should be considered. Polyethylene insulation, due to its good chemical stability and waterproof performance, is suitable for pipe insulation in various environments.

[0024] In air conditioning systems, the function of insulation pipes extends beyond just heat insulation. They effectively prevent condensation, avoiding water droplets on the pipe surface due to excessive temperature differences, thus preventing corrosion. Furthermore, insulation pipes reduce noise transmission, minimizing the impact of noise generated during air conditioning operation on the surrounding environment. When installing air conditioning insulation pipes, it is crucial to ensure a tight seal between the insulation material and the pipe, avoiding gaps to prevent heat loss and condensation. The thickness of the insulation pipe is also a key factor affecting insulation effectiveness, typically selected based on the pipe's outer diameter and the operating environment. For example, for copper pipes with an outer diameter less than or equal to 12.7mm, the insulation layer thickness should be at least 15mm; for outer diameters greater than or equal to 15.9mm, the insulation layer thickness should be at least 20mm.

[0025] The installation of air conditioning insulation pipes must be strictly carried out according to specifications. First, suitable insulation material must be selected based on the pipe's outer diameter, the operating environment, and the specific requirements of the air conditioning system. Second, during installation, ensure the insulation material fits tightly against the pipe, avoiding gaps. For irregularly shaped pipes, use specialized cutting tools to cut the insulation material into suitable shapes to ensure a perfect fit to the pipe surface. Furthermore, fire prevention and waterproofing measures are necessary during installation. Some insulation materials (such as polyurethane insulation) have good fire resistance, but contact with open flames should still be avoided during installation to prevent fires. For waterproofing applications (such as basements and bathrooms), insulation materials with good waterproofing properties should be selected, and appropriate waterproofing measures should be taken during installation, such as wrapping the outside of the insulation layer with a waterproof membrane, to prevent moisture from penetrating into the insulation layer and affecting its insulation effect.

[0026] After installation, the air conditioning insulation pipes need to be carefully inspected to ensure that the insulation material is securely installed without any loosening or detachment. The surface of the insulation layer should also be checked for smoothness, damage, or cracks. If any damage or cracks are found, they should be repaired promptly to prevent heat loss through these areas. During the operation of the air conditioning system, the insulation pipes also require regular maintenance. Checks should be made to ensure the insulation effect remains effective and that the insulation material is not aging or damaged. If a decrease in insulation effectiveness or damage to the insulation material is observed, it should be replaced immediately to ensure the normal operation of the air conditioning system.

[0027] Choosing the right air conditioning insulation pipe is crucial for the efficient operation of an air conditioning system. Substandard insulation materials can cause premature aging of the insulation pipe, affecting the air conditioning's performance and even releasing harmful substances. Therefore, when selecting air conditioning insulation pipes, priority should be given to materials that meet national standards for thermal conductivity, density, water absorption, and moisture permeability. Furthermore, the specific operating environment and pipe type must be considered when selecting appropriate insulation pipes. For example, in humid environments, insulation materials with good waterproof properties should be chosen; in fire-resistant applications, insulation materials with good fire resistance should be selected.

[0028] Air conditioning insulation pipes play an indispensable role in air conditioning systems, and their material selection, installation, and maintenance directly affect the operating efficiency and lifespan of the air conditioning system. By properly selecting and installing air conditioning insulation pipes, energy loss can be effectively reduced, the overall performance of the air conditioning system can be improved, and users can enjoy a more comfortable and energy-efficient experience.

[0029] like Figures 1-5As shown, the anti-brittle fracture and leakage air conditioning insulation pipe 1 includes an insulation pipe 1 and reinforcing sheets 2. The insulation pipe 1 has several sets of reinforcing sheets 2 arranged circumferentially inside to reinforce the pipe body and prevent brittle fracture. A protective film 3 is installed on the outside of the insulation pipe 1. Sealing rings 5 ​​are provided at both ends of the insulation pipe 1. The insulation pipe 1 has a connecting groove circumferentially opened inside to accommodate the reinforcing sheets 2. The reinforcing sheets 2 are fitted and inserted into the insulation pipe 1 for fixation, so that the reinforcing sheets 2 can fit tightly against the inner wall of the insulation pipe 1, enhance the overall strength of the pipe, effectively prevent brittle fracture caused by external impact or temperature change, and extend the service life of the pipe.

[0030] Please see Figures 2-4 A resin adhesive is provided between the protective film 3 and the insulation pipe 1. The protective film 3 is adhered to the insulation pipe 1 through the resin adhesive. The resin adhesive enhances the adhesion between the protective film 3 and the insulation pipe 1 and provides an additional layer of waterproof and moisture-proof protection, further improving the sealing performance of the pipe and preventing external environmental corrosion of the insulation pipe 1. Both ends of the insulation pipe 1 are provided with connecting grooves to accommodate the sealing ring 5. The inside of the connecting grooves is lined with sealant 10. The insulation pipe 1 is attached to the sealing ring 5 through the sealant 10. The combination of the sealant 10 and the sealing ring 5 can effectively prevent refrigerant or liquid from leaking from both ends of the pipe, ensuring the sealing performance of the pipe, reducing energy loss due to poor sealing, and improving the operating efficiency of the air conditioning system. A rubber gasket 4 is installed inside the insulation pipe 1. The rubber gasket 4 is attached and fixed to the insulation pipe 1. The flexibility and elasticity of the rubber gasket 4 can absorb the vibration generated by the pipe during operation, reduce noise, and further enhance the sealing performance of the pipe to prevent refrigerant leakage.

[0031] Please see Figures 3-5 Both ends of the insulation pipe 1 are equipped with threaded connectors 6. A threaded ring is provided inside the insulation pipe 1, and the threaded connectors 6 are threadedly fixed to the insulation pipe 1. The use of threaded connectors 6 makes the pipe connection more secure and reliable, facilitating installation and disassembly, and also improving the overall stability of the pipeline system, reducing the risk of leakage due to loose connections. A pressure detection module 7 is provided on the outside of the insulation pipe 1. A connecting rod 8 is installed at one end of the pressure detection module 7. The pressure detection module 7 can monitor pressure changes in the pipeline in real time, promptly detect abnormalities, ensure the safe operation of the pipeline, and provide data support for system maintenance. Both the outer ends of the insulation pipe 1 and the protective membrane 3 have connection holes to accommodate the connecting rod 8. The connecting rod 8 extends through the insulation pipe 1 into the interior, and a butt joint 9 is fitted onto the outer end of the connecting rod 8. The butt joint 9 engages and seals with the connection hole, ensuring the stable installation of the pressure detection module 7. The sealing performance of the pipeline is further enhanced by the engagement and sealing method, ensuring the accuracy and reliability of the detection data, while avoiding the influence of the external environment on the detection module.

[0032] During the production of the entire insulation pipe 1, several sets of reinforcing soft sheets 2 are first installed circumferentially inside the insulation pipe 1 and fixed to the connecting groove inside the insulation pipe 1 by fitting and plugging. This helps to disperse the external force on the insulation pipe 1. Next, rubber gaskets 4 are fitted and installed inside the insulation pipe 1, and a protective film 3 is adhered to the outer wall of the insulation pipe 1 with resin adhesive. The resin adhesive enhances the adhesion between the protective film 3 and the insulation pipe 1 and also provides an additional layer of waterproof and moisture-proof protection for the insulation pipe 1. Finally, sealing rings 5 ​​are laid at both ends of the insulation pipe 1. To prevent refrigerant or liquid leakage from both ends of the pipe, after the sealing ring 5 is bonded to the insulation pipe 1 by the sealant 10, the pipe is inserted into the insulation pipe 1. The rubber gasket 4 is used to tightly fit the pipe and fill the tiny gaps at the connection. Combined with the sealing ring 5, it provides double sealing protection for the pipe connection, effectively preventing liquid or gas leakage from the connection. After the pipe to be protected passes through the insulation pipe 1, the threaded connector 6 is used to fit the outer insulation pipe 1 and fix it. The threaded connector 6 is also used to fix the pipe to one end of the equipment, making the pipe connection more secure and reliable, reducing the risk of leakage due to loose connection. During the long-term use of the insulation pipe 1, the pressure detection module 7 can monitor the pressure changes in the pipe in real time. Once an abnormality is detected, an alarm can be issued in time for handling, ensuring the long-term stable use of the insulation pipe 1.
