The "ICT China (2023) Case Collection and Release" activity aims to promote basic research on ICT applications, highlight key technologies, cutting-edge leading technologies, and disruptive technological innovations, provide strong support for building a manufacturing power, a quality power, a network power, and a digital China, and find "Chinese samples" for the in-depth application of ICT in cities or industries.

With the rapid development of technologies such as the Internet of Things, big data, and artificial intelligence, the traditional cloud computing model can no longer meet the needs of real-time, low latency and high reliability, thus accelerating the incremental development and technological innovation of data centers, and promoting the development of data centers in the direction of high energy efficiency, intelligence and greening.

In order to cope with the challenges of high PUE value of data centers, complex network operation and maintenance, large footprint, low integration and long construction period, Haiwu has launched solutions and products that can be used in all scenarios such as computing power network shelters, low-resistance dual-channel indirect evaporative cooling air conditioners, integral all-weather energy-saving units, ultra-efficient fluorine pump air conditioners, and modular intelligent fluorine pump multi-connection air conditioning systems.

In a pilot project in Zunyi, Guizhou, the customer required a new computer room with high protection performance and emergency response mode, and met the needs of low-energy operation, rapid deployment, high capacity, and rapid O&M. The computing power network shelter adopts a fully modular and integrated design, including ICT cabinet system, power supply and distribution system, refrigeration system, etc., which can perfectly meet customer needs.

The computing power network shelter adopts standardized design and IP55 level protection measures to ensure the safety and stability of the computer room. By using fluorine pump dual-circulation air conditioning and photovoltaic technology, energy consumption is greatly reduced; The factory prefabricated assembly and modular design allow the shelter to be quickly deployed within 8 hours, providing great flexibility and efficiency. The high-density integrated IT cabinet and compatibility with multiple ICT devices meet the requirements of high-capacity operation and simplified operation and maintenance. The computing power network shelter not only meets the individual needs of the pilot project in Zunyi, Guizhou, but also demonstrates excellent product strength in terms of efficiency, energy saving, reliability, security, rapid deployment and operation and maintenance efficiency.

In a data center project in Datong, Shanxi Province, the customer urgently needed to build a new high-efficiency, energy-saving and green data center room. The project plans to build a two-story building with about 20,000 square meters per floor, and the main computer room contains 400 cabinets, each with a heat flux density of about 11kW, and the overall PUE value is required to be less than 1.2.

According to the local climate characteristics and combined with customer needs, Haiwu provides low-resistance dual-channel indirect evaporative cooling air conditioners, which can ensure low PUE with an energy efficiency of up to 13.5 throughout the year, and can also use the natural cold source for a long time to reduce compressor operation. Through intelligent control and innovative design, such as dual-channel layout and external key components, it not only greatly saves indoor data center area and improves data center utilization, but also achieves rapid response and high reliability, effectively improving the energy efficiency and space utilization of data centers.

In a data industry base project in Huailai, due to the relative scarcity of water resources, the customer required the solution to attach great importance to water conservation and utilization efficiency, and the overall PUE value was less than 1.25. To address this challenge, Haiwu proposes an integral all-weather energy-saving unit that reduces compressor power consumption through innovative low-voltage ratio compressor technology, reduces data center PUE to 1.19, and improves energy efficiency.

The solution adopts a prefabricated modular design to speed up the construction cycle, and further optimizes the use of energy and water resources through the precise control of full frequency conversion devices, which not only improves the energy efficiency and operational efficiency of the data center, but also significantly reduces the dependence on precious water resources, demonstrating the role of technological innovation in improving the sustainability and environmental friendliness of the data center under specific environmental conditions.

In a computer room project of Zhengzhou Unicom, the customer requirements: the unit is energy-saving and efficient, and can make full use of the natural cooling source; Easy installation and short commissioning cycle; Closed cold channel to increase return air temperature; intelligent operation, convenient control, monitoring with alarm information, etc. According to the site layout and customer needs, Haiwu modular intelligent fluorine pump multi-unit air conditioning system is adopted.

The outdoor unit adopts mechanical refrigeration coil + natural cooling coil, mechanical cooling mode in summer, natural cooling + mechanical cooling mixed mode in the transition season, and natural cooling mode in winter, making full use of the outdoor natural cooling source and greatly improving the energy efficiency of the whole machine. In terms of installation, the modular design and simplified system shorten the installation and commissioning time and respond quickly to customer needs. In addition, the closed cold aisle design effectively improves system efficiency, while the intelligent monitoring system ensures the reliability of equipment operation and the convenience of maintenance, which has been affirmed by the project party.

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 follow the trend of the times, release the vitality of enterprises, and provide more new technologies, new solutions, new applications and new achievements for the construction of digital China!
