"High-efficiency computer room" can be said to be a hot word in the market of central air-conditioning public equipment projects in the past two years, and it has been given a stronger color on the road of high-efficiency development of the whole industry.

On February 20, 2021, the State Administration Bureau issued the "Energy and Resource Consumption Quota for Central and State Organs", which clearly requires all departments and units to take energy and resource consumption quota management as a new development concept, formulate energy efficiency improvement plans, and take effective measures to continuously improve the utilization efficiency of energy resources, To make due contributions to China's efforts to reach the peak of carbon dioxide emissions by 2030 and achieve carbon neutrality by 2060. On February 22, 2021, the State Council issued the guiding opinions on accelerating the establishment and improvement of a green and low-carbon circular development economic system, which made arrangements for green and low-carbon circular development from six aspects, including production, circulation, consumption, infrastructure, green technology, laws, regulations and policies, and defined 85 key tasks and leading units. It is foreseeable that the introduction of the two policies will have a profound impact on the development of efficient computer rooms.

What is worth looking forward to is that with the participation of more and more participants and more and more perfect policies, the process of efficient computer room construction will become faster and better, and the "spring" of university computer rooms that we are looking forward to will eventually come.

Where do 1. come from?

The concept of high-efficiency computer rooms comes from overseas, and it has taken the lead in countries with higher energy-saving requirements such as the United States and Singapore. In recent years, in the domestic HVAC market, with several high-efficiency computer rooms built in the early stage of Guangdong, they have shown excellent energy-saving and installation efficiency. The concept and practice of high-efficiency computer rooms are recognized by more and more professionals and owners in the industry, and the application fields are becoming more and more extensive.

2. efficient machine room

Efficient computer room mainly has three important components,

First, efficient equipment, mainly including chillers, water pumps, cooling towers and other air conditioning room main energy consumption equipment;

The second is the energy-saving deepening design of the waterway system, the main goal is to reduce the system resistance and reduce the energy consumption of the transmission and distribution system;

Where will the 3. go?

Industry, transportation and construction are the three major areas of energy consumption in China. The energy consumption of central air conditioning systems in modern large buildings accounts for 40-55% of the overall energy consumption of buildings, the energy consumption of refrigeration rooms accounts for 65-75% of the energy consumption of central air conditioning, and the energy consumption of refrigeration rooms accounts for 30-35% of the whole year of buildings. Therefore, under the background of carbon neutrality, reducing HVAC energy consumption is of great significance to achieve energy conservation and emission reduction.

In June 2019, the state issued and implemented the Green and Efficient Refrigeration Action Plan, which proposed that "by 2030, the refrigeration energy efficiency of large public buildings will be increased by 30%, the overall energy efficiency level of refrigeration will be increased by more than 25%, and the market share of green and efficient refrigeration products will be increased by more than 40%. It can be seen that in China, the concept of efficient computer room has risen to the national level, but at present, the development of efficient computer room in China is still in its infancy, and most of the building air conditioning systems in China are still large energy consumers.

Zhang Quan, a professor at the School of Civil Engineering of Hunan University, pointed out that the main way to control the building energy consumption index is the high-efficiency computer room, which provides strong support for the realization of the goal of carbon neutrality. Secondly, the high-efficiency computer room can improve the overall technical level of the HVAC industry and provide application requirements and scenarios for technological innovation in HVAC-related industries. * After that, the high efficiency of the refrigeration room determines the building energy consumption level, there are about 30-50% energy-saving potential can be tapped.

For equipment manufacturers to intervene in this market, first of all, they need to give full play to their advantages in the research and development and design of air-conditioning equipment, and develop host products that are more efficient and more suitable for the application characteristics of the project;

Secondly, it is necessary to supplement the short board in HVAC design, learn from industry experts and design institute experts, and supplement relevant design and application talents. At the same time, the efficient computer room project needs the whole process management service, which needs attention from scheme design, system application, installation and debugging, maintenance and management, etc. The lack of any link may affect the final use effect, which also requires corresponding technical reserves and talent supplement;

After *, it is also necessary to make more innovations and explorations in the application of business cooperation models in efficient computer rooms, so as to more favorably promote the application of efficient computer room projects and enable them to land and develop.

The third is the intelligent control system and the energy consumption and energy efficiency evaluation system. For the high-efficiency computer room, there must be a perfect and accurate monitoring and energy consumption and energy efficiency evaluation system, which can clearly understand the energy efficiency of each equipment and system, compare and analyze the difference between the design efficiency and the actual operation efficiency, and continuously optimize the operation strategy by using the intelligent control system to ensure the continuous high efficiency of the air conditioning system.

For the manifestation of high-efficiency computer rooms, several major schools have gradually formed in the market, such as "assembled computer rooms", such as "integrated computer rooms", and "integrated refrigeration stations". While the system is efficient, installation and construction The "high efficiency" of the company has gradually become the common goal of many "A and B" parties.
