Lean air-conditioning assembly Chinese "locomotive" exported to Germany for the first time
On the evening of June 20, local time, in Berlin, the capital of Germany, CRRC Zhuzhou Locomotive Co., Ltd. and Deutsche Bahn signed a framework agreement for 20 new hybrid "locomotives" and an order for the first batch of four locomotives, marking the integration of China's rail transit equipment. The locomotive products have been recognized by the world's high-end market. The locomotive produced by CRRC Zhuzhou Electric Locomotive Co., Ltd. is equipped with a Lean locomotive air-conditioning unit, marking the first time that Lean rail transit vehicle air-conditioning products have entered the German national railway locomotive market!
According to technical experts from CRRC Zhuzhou Locomotive Company, the academic name of the "locomotive" signed this time is "shunting locomotive". It is designed in full compliance with TSI (European Railway Interoperability Specification) standards and the German Railway Network EBA network access requirements, using the "third party It adopts the hybrid electric transmission mode of "rail + internal combustion + lithium battery", with a maximum power of 750kw for the entire wheel circumference and a top speed of 100 kilometers per hour. This type of vehicle can operate on the German mainline railway network, TEN sections and Berlin light rail lines. It is mainly used for logistics supply, testing and engineering traction at railway construction sites.
The air conditioning system of this new hybrid locomotive is a KLD5.0 air conditioning unit independently developed and produced by Jingyi. It has a cooling capacity of 5.0kw, an air supply volume of 1400m³/h, a weight of 135KG, a total power of 5.4kw, and a heating capacity of 5.0kw. It can automatically Adjust the air parameters of the battery cavity to ensure the normal operation of the vehicle.
The JingyiGroup KLD5.0 air conditioning unit is lightweight, resistant to vibration and impact, has safe and reliable performance, and is easy to repair and maintain. Its structural type is a roof unit type. Air is supplied from the bottom of the front box and returned from the bottom. The cold air passes through the air duct in the car. Introduce it evenly into the car on both sides. The unit adopts mechatronics design. The electrical control system of the unit is integrated in the air conditioning unit and is connected to the BMS network of the battery via CAN communication and hard-wired signals. The controller receives signals from the BMS and also feeds back the status to the BMS to realize ventilation, The automatic control of cooling and heating is easy to operate and saves space in the control cabinet in the vehicle.
Based on its advantages in technology and manufacturing resources in the field of transportation refrigeration, Jingyi Group officially initiated the development of rail transit air-conditioning projects in 2009. In July of that year, it established Guangzhou Jingyi Transportation Refrigeration Equipment Co., Ltd., which is a wholly-owned subsidiary of Guangzhou Jingyi Industrial Group. Focus on the R&D, manufacturing and sales services of rail vehicle air conditioning system products. At present, dozens of series of unit air-conditioning units and inverters for locomotives have been formed, including large railway vehicle air-conditioning series, locomotive air-conditioning series, subway air-conditioning series, trams, sky trains, maglev trains, intercity and high-speed train air-conditioning units. Air conditioning units, with integrated supply capabilities for rail vehicle air conditioning, air ducts and control systems.
Jingli will be committed to the long-term research and application of transportation refrigeration technology, including rail transit, and build Jingli into a world-leading service manufacturer in the field of international transportation refrigeration.
