CRRC Qishuyan Locomotive and Rolling Stock Technology Research Institute Co., Ltd. (hereinafter referred to as "CRRC Qishuyan Institute") was founded in 1959. It is a wholly-owned subsidiary of CRRC and a professional research institution for rail transit equipment materials and manufacturing processes in my country. National high-tech enterprise.

The first workshop of CRRC Changzhou has an area of about 13,000 square meters and a height of about 11 meters. The second workshop covers an area of approximately 17,000 square meters and is approximately 11 meters high. Due to the dense distribution of machines in the customer's company's workshop, the large number of people, and poor ventilation, the workshop is very stuffy in summer, coupled with the greasy smell generated by the machinery and equipment during production. In line with the "people-oriented" management service concept, the company's senior management began to conduct various surveys on ventilation and cooling projects, striving to improve the workshop working environment as soon as possible, improve employee satisfaction, and become an excellent company that is responsible for society and employees. Our company, Xiaweiyi Company, was also fortunate to be one of the research subjects. Professionals went to the customer site and learned that the layout of the customer's company was not particularly ideal. The equipment in the workshop is densely packed, and the design of the ventilation and cooling scheme is relatively complicated. There are many large ceiling fans on site that simply cannot solve the problem on hot summer days. On the contrary, it will fan down the hot air, causing secondary impacts. In the environmental improvement project, the customer took many detours. We measured a lot of important data at the customer's company and learned about the customer's specific cooling requirements and other related information. Then I went back to the company to discuss the design of the plan with my colleagues and leaders. During this period, because the customer had not come into contact with our fan + environmentally friendly air-conditioning ventilation and cooling solution before and the detours we had experienced before, we took the customer to the customers who had completed the transaction for three consecutive days to learn about the successful cases, including Oaks Air Conditioning, Hengshun Vinegar, Use the cases of large enterprises such as Dingsheng Aluminum to experience the effects firsthand. As the saying goes, seeing is believing. After inspecting successful cases, customers have initial confidence in the effects of our company's products. In addition, our technical director personally continuously provides customers with various technical solutions to solve their problems, and finally tailors the most suitable solution for customers. Ventilation and cooling system solutions for on-site needs.

Xiaweiyi's entire set of ventilation and cooling equipment adopts an integrated intelligent automatic control system. The number of ventilation and cooling system equipment can be turned on or off according to the commuting time, required temperature and humidity, the system automatically and intelligently adjusts, the integrated control method, and the system has protection measures such as phase loss, overload, and leakage. Keep the workshop within a certain temperature and humidity range (under the premise of meeting the workshop cooling requirements and not bringing other negative impacts to the customer's production site, such as humidity problems) to reduce the waste of energy consumption. The system can set administrator permissions and management People enter the management software with passwords, saving 30% of the energy waste caused by human control, and greatly improving management efficiency.

During the bidding process, because we designed an ideal solution and the equipment and materials used fully met or even exceeded the standards required by our customers, our price was on the high side, nearly 4 million. Some of the prices of the other three peers are even more than 30% lower than ours. In the process of explaining to the leaders of the customers, the company leaders were calm and confident. Based on the experience of many successful cases of large enterprises, they were confident and clear-cut.

The data shows that our company’s ventilation and cooling system completely exceeds the customer’s requirements (the customer requires that when the outside temperature is greater than 36 degrees in summer, the overall temperature in the workshop should not be higher than 35 degrees, and the measured maximum temperature should not exceed 33 degrees, and the entire workshop should be maintained at 29 degrees. -33), and greatly improved the previous greasy smell in the workshop, making it very cool and comfortable. It has greatly improved workers' production enthusiasm, improved production efficiency, generated income for the company, and won unanimous praise from customers.

We believe: We will definitely take advantage of this opportunity to cooperate with CRRC to ride on the high-speed train of CRRC. Safety, quality and efficiency are all indispensable.

Heading towards a better future!
