Recently, the China Electronics Energy Conservation Technology Association announced the winners of the "2023 Cloud Computing Center Science and Technology Award", and Haiwu AHU indirect evaporative cooling energy-saving unit stood out among many selected technology projects with its outstanding innovation strength and won the "Cloud Computing Center Science and Technology Award - Excellence Award". The association will hold a grand award ceremony at the China Data Center Market Annual Conference on August 9, 2023.
The "Cloud Computing Center Science and Technology Award" is reviewed and filed by the National Science and Technology Award Office (Award No.: 0319), which is the only award given in the field of cloud computing center science and technology in the social science and technology award catalog, aiming to reward the scientific and technological innovation achievements and products applied by the green cloud computing center for economic and social development and national energy conservation and emission reduction.
Under the "dual carbon" strategy, the construction and transformation standards of cloud computing data centers have been continuously improved, showing a development trend of scale, intensification and energy saving.
As a new temperature control technology means for data centers, Haiwu AHU indirect evaporative cooling energy-saving unit integrates the natural cooling technology of high-efficiency evaporative cooling system on the basis of air-air heat exchange technology, compared with traditional air-cooled air conditioners with the characteristics of dual-core layout, leak-proof design, compact and land-saving, and maximizes the use of natural cooling sources through heat exchange cores to achieve the cooling needs of data rooms, so as to achieve energy conservation and carbon reduction effects, which is the preferred solution product for long-term sustainable development.
Highlight 1: Integrated design of large cooling capacity
Haiwu AHU indirect evaporative cooling energy-saving unit has a single cooling capacity of up to 400kW, adopts an integrated design, with built-in cooling supplementary system, water spray system, water filtration system, air-air heat exchanger, control system, etc., forming a prefabricated module, which can be quickly deployed and increase the cabinet rate by 20%.
Highlight 2: Original dual-channel layout
The unit adopts an innovative dual-channel layout, shortens the length of the flow path by 50%, reduces the resistance of the core by 30%, expands the heat exchange efficiency area of the core, greatly improves the heat exchange efficiency of the core, and improves the energy efficiency of the whole machine by 20%. In addition, the dual-channel layout reduces multi-core assembly, eliminates risks such as deformation, air leakage, and water leakage, and is easy to maintain.
Highlight 3: Three intelligent operation modes
The unit has three basic operating modes: dry mode, wet mode, and mixed mode, which can intelligently switch between the optimal operating mode according to the indoor and outdoor ambient temperature. Operate dry mode under low temperature conditions in winter and early spring, wet mode in spring and autumn, and mixed mode in summer conditions, make full use of natural cooling sources, reduce mechanical cooling power and duration, and reduce energy consumption.
Haiwu digs deep into the needs of industry users, and contributes to the development of the information economy and energy conservation and emission reduction based on its own practical experience and scientific and technological innovation achievements. In the future, Haiwu will continue to explore and actively innovate, climb the peak of energy-saving technology, provide more low-carbon and energy-saving data center solutions, promote the industrialization of cloud computing data center scientific and technological achievements, and promote the green and efficient development of the cloud computing data center industry.
