DASEN News

On June 7th, the "Cold Chain Brother" short video account launched a special report on DASEN Refrigeration, and DASEN's green and environmentally friendly integrated refrigeration system quickly attracted widespread attention in the industry.

Cold Chain Brother "is a short video account owned by Liu Peijun, the founder of Beijing Fast Line, with over 10000 followers, mostly professionals in the cold chain industry. "Beijing Multi temperate Urban Big Refrigerator" (Beijing Express Line - China Resources Wanjia Dry Warehouse Reconstruction Cold Storage Project) was independently designed and constructed by Dashen Refrigeration. The project was completed in 2022. So far, the project has been running smoothly for one year, and has achieved remarkable energy saving effects.

Liu Peijun, the founder of Beijing Fast Line, frankly stated that the top choice for building an energy-saving and environmentally friendly "Beijing Multi Temperate City Refrigerator" is the CO2 refrigeration system expert, Dasen Refrigeration.  

As a technology innovation enterprise with a strong sense of historical responsibility and mission, Dassen Refrigeration has taken the lead in increasing research and investment in carbon dioxide refrigeration technology in the industry. It has obtained more than 20 patents for various carbon dioxide refrigeration technologies and has won the Innovation Product Award at the China Refrigeration Exhibition for four consecutive years. In recent years, it has completed more than 50 large and medium-sized carbon dioxide refrigeration projects, reducing the amount of Freon filling by more than 3 million tons of carbon emissions.

This time, the Beijing Express Line - China Resources Wanjia Dry Warehouse is being built to transform the cold storage, which also uses CO2 as the refrigerant. At the same time, the refrigeration system uses CO2/R507 cascade loading cooling system and Freon direct expansion system. The cascade loading cooling system uses CO2 refrigeration equipment, and the Freon direct expansion system uses the form of refrigeration stations on the east and west sides, which greatly saves the floor area and construction costs. The fan defrosting also uses water flushing and is equipped with floor heating. The temperature of the winter water pool and the heating source of the floor both come from the waste heat of the high-temperature section of the system. With the support of multiple energy-saving measures by DASEN, the "Big Refrigerator" has truly achieved the most efficient use of energy.

The mystery behind the flexible temperature regulation of the 10000 ton "multi temperature belt large refrigerator" that surprised CCTV reporters.

The "Beijing Multi temperate Urban Refrigerator" (Beijing Express Line - China Resources Wanjia Dry Warehouse Reconstruction Cold Storage Project) cold storage has a total capacity of 25000 tons, a height of 10.5 meters, and is divided into five temperature layers, covering all temperate zones from minus 45 degrees to minus 18 degrees. The temperature can be flexibly adjusted at any time according to the environment required by different customers to store goods. CCTV reporter Dong Bin once wondered during his visit to the "Big Refrigerator" how to achieve multi temperature regulation using only a few machines in a 25000 ton cold storage? Omori Refrigeration has provided the answer with its ingenious refrigeration system design.

Remote control supported by the "Yi Leng" refrigeration cloud platform

The 'Big Refrigerator' is equipped with the independently developed 'Easy Cooling' remote monitoring system by Dassen, which allows real-time operation of the device even from thousands of miles away through mobile phones or computers. It has more functions such as fault warning diagnosis, data query and tracing, big data analysis, system warranty maintenance, and archive management. Make the system run more intelligently and operate more conveniently.

The high fault tolerance and wider energy efficiency adjustment range brought by the backup multi head design

The high temperature section and CO2 section of the "Big Refrigerator" CO2 stacked loading refrigeration system are both in parallel unit form. Even if a single machine head fails, several other machines can still work. At the same time, under the background of multiple machine heads, the refrigeration capacity generated by the unit always matches the actual production demand, and the energy efficiency adjustment range is wider, thus achieving the goal of more efficient and energy-saving.

Behind the unexpected delivery of the project is the mature design and construction management system of Dassen Refrigeration.

After 8 months of design, construction, joint debugging, and cooling, the "Beijing Multi Temperate City Refrigerator" successfully achieved control of various temperature zones and passed various government regulatory inspections. At the same time, during the one-year operation of the cold storage, various indicators exceeded expectations. Behind all these "unexpected" results is the mature design and construction management system of Dassen.

At the beginning of the project, the DaSen professional design team designed a CO2 stacked cooling system that is more suitable for the "Beijing Urban Refrigerator" based on its green, environmentally friendly, and energy-saving needs. At the same time, BIM 3D drawings and other technologies were applied to make the design process more accurate, efficient, and visualized. During the construction process, the DASEN construction team also developed a special construction plan for the Beijing urban refrigerator based on detailed and strict construction standards. From equipment installation to every screw assembly, there is a complete quality management system, and the acceptance process follows DASEN's "self inspection before reporting" acceptance procedure to ensure that the acceptance is passed in one go.

As the founder of Fast Line, Liu Peijun, once said, choosing DASEN is the most correct thing I have ever done. The 'Beijing Multi Temperate City Big Refrigerator' will also become another boutique project of Dasen. After 26 years of deep cultivation in the refrigeration industry, Dasen Refrigeration has always stood in the customer's perspective, with technology and innovation as its wings, insisting on the research and development and use of green refrigeration technology. Dasen, make refrigeration greener!
