From October 17th to 18th, the third “Belt and Road” International Cooperation Summit Forum was held in Beijing. During the period, CRRC Changchun Rail Bus Co., Ltd., a subsidiary of CRRC, and the Serbian Ministry of Construction, Transport and Infrastructure officially signed a commercial contract for the purchase of Serbian high-speed EMU vehicles. This is a major breakthrough for China’s high-end rail transit equipment to “go global.”
The train will be equipped with an air-conditioning system designed and produced by Guoxiang Company, a subsidiary of CRRC Qiche Group Shijiazhuang Company. It is reported that the trains signed this time are power-dispersed electric multiple units, including 20 (5 trains) high-speed EMUs. The vehicles are composed of 4 vehicles (2 power and 2 tow), with a maximum operating speed of 200 kilometers per hour. It is planned to be put into use in 2025. .
The Hungary-Serbia Railway is a landmark project of the “Belt and Road” jointly built by China and Central and Eastern European countries. The total length of the line is 341.7 kilometers. After the project is put into operation, the travel time between the capitals of Hungary and Serbia will be shortened from 8 hours to 3 hours. Based on the positioning of “Expert in Passenger Room Air Management”, Guoxiang Company continues to enhance its independent innovation capabilities and carries out product design and technical research around “energy saving, environmental protection, intelligence, and comfort”. For the first time, it uses R513A low-GWP refrigerant and parallel compressor technology in EMUs. , can effectively perform different cooling outputs of 25%, 50%, 75%, and 100%, allowing the system to operate in the most energy-saving working condition, providing comfortable air conditioning for vehicles and reducing the greenhouse effect.
“Our products have a strict quality control system, and multiple inspections are implemented throughout the quality control process. The welding workshop has a welding laboratory that can complete metallographic, tensile, bending and other experimental tests. In terms of details, we maximize Control the precision of special processes, key processes, appearance, and assembly processes, ensure quality from the source, and reflect the process quality of products in every detail.” Sun Yongjin, chief engineer of the Guoxiang Company Technology Center, said that the high-speed EMU unit signed this time is China’s top speed The high-speed EMU with a length of more than 200 kilometers was exported to Europe for the first time. The cabin air conditioner tailor-made for the Hungary-Serbia EMU is smarter, greener, more comfortable, and more environmentally friendly, and fully meets European industry standards.
Different from the past, the biggest feature of the train air-conditioning project exported to Europe this time is that it is used in supporting high-speed EMUs on subway platforms (non-profile installation). The units all protrude from the outside of the roof, which also ensures processing difficulty and reduces manufacturing costs. .
It is understood that since the technical solution design was carried out at the end of 2022, Guoxiang Company has actively communicated with the main engine manufacturers, gained an in-depth understanding of the Serbian market, and is committed to providing leading technology, energy-saving and environmentally friendly products and high-quality services for local rail transit equipment. In the future, the company will always focus on the comfort of users “between heating and cooling”, focus on the research and development and manufacturing of high-efficiency, energy-saving and environmentally friendly air conditioning systems, strive to improve the stability and intelligence of air conditioning systems, and continue to create an innovative “strong magnetic field” to help green We have made unremitting efforts to develop low-carbon and intelligent rail transportation equipment.
