According to the latest economic operation of the automobile industry released by the China Association of Automobile Manufacturers, in the first three quarters of 2022, my country's automobile production and sales continued to maintain a rapid growth trend, completing 2.672 million and 2.61 million vehicles respectively, a year-on-year increase of 28.1% and 25.7%, respectively. Automobile production and sales hit a record high. With the rapid development of my country's automobile industry, the demand for domestic automobile hoses has increased significantly. my country has become the world's largest consumer market for rubber hoses, and its growth rate ranks among the top in the world. It is estimated that by 2022, the market size of the automotive air-conditioning industry will reach 2 billion yuan. .
As a supporting component of the automobile heat exchange system, the performance and quality of automobile air-conditioning pipeline directly affect the safety and comfort of the vehicle. As the country has higher and higher requirements for energy conservation and environmental protection of complete vehicles, automotive air conditioning systems have a greater impact on vehicle energy consumption. At the same time, the market's requirements for automotive air conditioners are gradually developing in the direction of environmental protection, high efficiency, energy saving, light weight, and noise reduction. And under the influence of consumption upgrades, automotive air conditioners are no longer only used for cooling and heating, but also to meet individual needs such as air purification.
Changing with the situation, Litong Technology awakens innovative ideas for lightweight automotive air-conditioning hoses
In response to the national requirements for energy conservation and environmental protection and to comply with the market development trend of automobile lightweight, Litong Technology began to develop and produce high-end automobile air-conditioning hose assemblies in 2015, relying on a professional technical research and development team, advanced processing and production equipment and testing and testing With the advantages of equipment and other advantages, Litong Technology has gradually mastered the key process of lightweight manufacturing of automotive air-conditioning hoses through independent innovation, and has strong thermal management system design and research and development capabilities. The tube has reached a new level in product quality, manufacturing technology level, core processing technology, etc., and further enhanced the market competitiveness of domestic and local brands.
With the popularization of energy saving, environmental protection and efficient refrigeration technology in refrigeration equipment, in addition to R-134a air-conditioning refrigerant, new refrigerants such as R290 and CO2 with outstanding environmental performance are also widely used in the field of automobile manufacturing. However, due to performance limitations, the cooling effect of the new refrigerant is not ideal under the original air conditioning system (mainly reflected in the fact that the cooling effect cannot meet the requirements), so it is necessary to improve the operating efficiency of the automotive air conditioning system through technical means, which is very important for automotive air conditioning hoses. There are extremely high requirements on material selection and process construction.
In order to meet the strict requirements of the automobile manufacturing industry on the performance of automobile thermal management system components, Litong Technology has changed according to the situation and broke through the circle. LT789 automotive air-conditioning hose implements the QC/T664-2000 standard and is made of special rubber with good weather resistance. It has the characteristics of more compact design, smaller bending radius and lighter pipe body. The hose uses nylon barrier material with ultra-low refrigerant permeability and low temperature permeability as the isolation layer, and has good heat resistance, ozone resistance, and abrasion resistance, and has become the quality choice for high-end automotive air-conditioning components at home and abroad.
