Wide range of application scenarios, customized production
The application scenarios of refrigeration equipment are very wideIt covers households, commercial buildings, rail transit, passenger stations, hospitals, schools, data centers, cold chain logistics, energy storage, and automobilesand other areas of daily production and life. Refrigeration products in most areas are individually designed according to the use scenario.
The wide range of downstream applications and the diversity of requirements have led to the characteristics of customized production in the refrigeration accessories industry. In addition, there are various types of refrigeration equipment, and different types of products are availablePerformance parameters, manufacturing process, application fields, customer groupsOn the basis of their own superior products, the representative enterprises in each segment have gradually expanded their product lines, refined product types, and improved the scope of product penetration, which will further strengthen the customized production characteristics of the refrigeration accessories industry, and put forward higher requirements for the corresponding speed of customized production of enterprises in the industry, which is conducive to enterprises with rapid customized delivery capabilities to increase market share.
The application of new refrigerants, the development of refrigeration accessories to miniaturization and integration
In the early days, the refrigeration equipment was relatively simple, and the refrigeration system pipe components mainly played the role of connection, and there were few special requirements. However, in recent years, with the gradual improvement of the country's requirements for the energy efficiency level of refrigeration equipment such as air conditioning and the popularization of high-efficiency refrigeration technology in refrigeration equipment, especially the use of new refrigerants such as R290 and CO2 with outstanding environmental performance, refrigeration accessories have a trend of development in the direction of miniaturization and integration.
In CO2 refrigeration systems, due to the high operating pressure, the refrigeration system tube assemblies need to be used with smaller pipe diameters to significantly improve the pressure resistance effect. The thermal performance of R290 refrigerant is more prominent, which is the long-term development direction of refrigerant. However, R290 has the disadvantages of flammability and explosion, so it requires more integrated design structure for refrigeration system tube components to minimize solder joints and prevent leakage; At the same time, in order to ensure safety, all countries strictly control the upper limit of R290 charging in refrigeration systems, and in order to reduce the charging amount of R290, the relevant refrigeration system pipe components are also developing in the direction of miniaturization. Enterprises with strong R&D, design and integrated processing capabilities of refrigeration accessories will benefit.
Aluminum products have excellent performance, and "aluminum instead of copper" is an important development direction in the future
At present, copper is used as the main raw material for air conditioning pipe fittings, but copper is relatively heavier, resources are relatively scarce, and materials are more expensive. The global reserves of aluminum are more abundant than copper, and aluminum** is lower than copper. The surface of aluminum in contact with external air can form a dense oxide film, which can isolate the contact between the internal aluminum and external corrosive substances, so that it has good anti-anthill corrosion performance. The density of aluminum is 1 3 of copper, and aluminum pipe fittings can realize the lightweight and low cost of refrigeration systems.
In order to meet the overall requirements of reducing costs and weight of air conditioning systems, air conditioning pipe fittings are gradually developing in the direction of aluminum as the main raw material. Enterprises with strong aluminum product processing and production capacity will continue to expand their market share with the promotion and application of aluminum.
