[XGNews]: “Carbon emission” challenge at present, vertiv technology brings energy-saving transformation best practices

The following is the [XGNews]: “Carbon emission” challenge at present, vertiv technology brings energy-saving transformation best practices recommended by xgapn.com.

The rapid development of digital economy undoubtedly needs the full support of the construction of new digital infrastructure. The new infrastructure with digitization as the core has been proved to greatly promote the technological innovation and process transformation of thousands of industries, so as to meet the development needs of new service industries and new economy.

As the core component of the new infrastructure, the data center has been regarded as the top priority related to the development of the new economy. Around the construction and operation of the data center, relevant national ministries and commissions have also issued a number of documents to provide specific guidance in recent years.

Due to the proposal of the “double carbon” goal, the country pays more and more attention to the carbon emission of the data center. On December 8, the national development and Reform Commission and other four departments jointly issued the implementation plan for implementing the requirements of carbon peak carbon neutralization goal and promoting the green and high-quality development of new infrastructure such as data center and 5g, which made requirements for the “double carbon” of data center.

According to the data from various sources, the racks of domestic stock data centers have reached more than 3 million to 4 million, and the new planning in the next few years may be about 1.2 million racks, which means that the energy-saving transformation of stock racks will play a decisive role in reducing the total carbon emission of data centers.

Survival proposition faced by data center Enterprises

As we all know, under the mandatory requirements of the policy and the support of various technologies, the pue of the new data center can be reduced below 1.3 – this indicator is also the premise of the new construction. If it is not met, it must not be started.

However, the pue of many existing data centers is much higher than 1.3, or even more than 1.8. Yan Han said, “the stock data center is more challenging for the realization of carbon neutralization, and its optimization role is self-evident.”

At the same time, the government has also made scientific and prudent requirements for the planning and construction of the data center to ensure that the overall carbon emission of the data center can be effectively reduced in the whole life cycle.

For example, the “equivalent substitution” in the planning stage means to build a new data center. Enterprises need to reduce the carbon emission of the stock data center before the new data center project can be approved.

However, there is often a gap between planning and practice. Many new data centers are designed with a pue of 1.3, but after the implementation, it has become 1.6, 1.7 or even higher, which is far from the previous goal.

Yan Han, senior manager of thermal management solutions Department of veriva Technology (vertiv, NYSE: VRT) in China, believes that the construction is only the beginning of the data center industrial chain. The key to how to truly implement the goal of carbon saving lies in the iteration and upgrading of later operation. Transforming the data center through various new technologies has become an inevitable choice for new data centers and stock data centers.

Internationally, the United States has closed a large number of data centers with pue higher than 1.5, with a total of 5000. Those countries with limited land resources and relatively scarce resources, such as Singapore, put forward extremely stringent requirements for the operation of existing data centers.

“The optimization of the stock data center actually has greater significance and role in reducing the whole carbon emission.” Yan Han said that in the policy issued by the Ministry of industry and information technology, it is clearly required that the pue of the transformed data center is less than 1.4. In some coastal areas, such as Zhejiang, the pue requirements for the stock data center are further reduced to less than 1.3.

Once the data center is not reached, it may be listed as a high-energy enterprise and face power cut-off or additional increase in electricity price. Therefore, optimizing the existing data center has become a survival proposition that enterprises must face.

Three pain points of data center transformation and optimization

Through long-term research and combing the existing cases, vertiv believes that the pain points faced by enterprises in the transformation and optimization of data centers mainly include three aspects:

One is compliance, which includes not only policy compliance, but also pue compliance, as well as water compliance. Yan Han said that the load rate of many domestic data centers is low, which has caused great waste and unnecessarily raised pue.

Now when it comes to the data center, many people’s first reaction is “electric tiger”. In fact, the data center also has a huge demand for water.

As a country with a relative shortage of water resources, China’s per capita water resources are 500 tons per person per year, less than 100 tons in North China, and the world average is 2000 tons – obviously, such a huge gap is difficult to reconcile.

What’s worse, the water transferred by the state (such as the South-to-North Water Transfer) will evaporate in the data center, which also brings great problems. Take Ulanqab with dense data centers as an example. Recently, the local government has issued relevant policies to prohibit the provision of groundwater to the data center.

Even in areas with sufficient water supply, data centers are also facing the challenge of substantial increase in water prices, which not only keeps the enterprise operating costs high, but also may make the business unsustainable.

The second pain point faced by enterprises is continuity, that is, the transformation will have an impact on the running business, and the data center is facing downtime, which will inevitably cause business losses and bring a series of unexpected problems.

Taking bank customers as an example, the data centers of some customers have been running for 20 years. If they are shut down rashly, it will not only affect the normal operation of various businesses of the bank, but also lead to the fluctuation of the whole financial market.

The third pain point is the cost. In the face of issues such as resource shortage and carbon emission, many enterprises are actually willing to respond, but the actual cost leads them to worry. Worse, they worry that if they invest resources, they will not get the ideal effect, which also affects the decisions of many data center managers to a certain extent.

Stable and feasible technical scheme

Therefore, one of the schemes proposed by vertiv is air cooling. Yan Han said that the transformation of the stock data center and changing the original water cooling into air cooling is the most stable and feasible technical scheme at present.

He pointed out that the advantages of air cooling are more obvious in the face of the needs of high reliability and low cost of data centers. Especially with the strengthening of electric energy technology and group control technology and the introduction of new AI technology, the energy efficiency of air cooling can reach a new height.

Compared with the high complexity of the water cooling system, the structure of the air cooling system of vertiv technology is simpler. Customers can fully control several core components such as variable frequency fan and variable frequency compressor through the control system.

In addition, a major advantage of the air-cooled system is the fast delivery speed.

Generally, the construction of cold water system in large data centers takes at least half a year, but the air cooling system of vertiv can be completed within two months, and the trend of modularization is obvious, and the construction time will be further shortened in the future.

In terms of business continuity, vertiv can help customers realize the gradual upgrading of the whole system. At the same time, due to the use of full frequency conversion fluorine pump technology, the existing problem that the centralized single point transformation requires the shutdown of the whole system is solved.

Yan Han cited a real case of a customer in Wenzhou, Zhejiang Province.

It is reported that with the help of vertiv technology, through the frequency conversion upgrading of the refrigeration system, this customer has achieved an overall decline in pue, from the previous average annual rate of 1.78 to 1.35.

More than that, in 28 months, the electricity saved by customers has exceeded the total investment of the project. In fact, in only 23.85 months, customers realized the complete recovery of investment, which is really the best effect.

Yan Han said that through the distributed system, vertiv technology can flexibly select the construction scheme in the way of ant moving, that is, how many computer rooms need to be built, so as to help customers minimize their investment and reduce the financial interest generated by bank lending.

Wisdom is everywhere in the solutions provided by vertiv.

For example, at a customer site in Tianjin, through AI solution, vertiv technology helped to realize the switching problem of cooling water system: stop the operation of some chillers during the day and use the cold water produced by the cold storage tank at night for the system to improve energy efficiency – as a result, pue was reduced by 0.2.

“Based on the above, we can achieve compliance, online operation and optimal cost.” Yan Han said that vertiv will help the data center achieve the best energy-saving transformation through excellent product solutions, in-depth product customization and comprehensive and efficient delivery.
