Shulou(Shulou.com)06/01 Report--

Sichuan Yimikang Environmental Science and Technology Co., Ltd. (hereinafter referred to as Yimikang) believes that by comprehensively and accurately measuring the load in the data center, the refrigeration system can be adjusted more accurately and flexibly. let the refrigeration system achieve the best efficiency. This requires data center users to accurately plan the load in the design, and set enough temperature and humidity measurement points in the computer room to configure precision air conditioning equipment and air supply devices that can flexibly adjust cooling and air volume.

Considering region, climate and application

Data center solution providers have long been committed to improving the efficiency of individual equipment in refrigeration systems. With the increasing energy consumption of the data center, the industry pays more attention to the improvement of the overall efficiency of the system in recent years.

In terms of technology, the application of energy-saving technologies related to data center refrigeration will be the focus in the next few years. As the size of the data center continues to grow, energy expenditure is a huge burden on the data center, prompting data center operators to try to adopt innovative energy-saving technologies by working with equipment manufacturers.

China has a vast territory and a great difference in climate between the north and the south, so the cooling methods of data centers in different regions are also different. In central and southern China, because the temperature is perennially high and lack of stable external cold source for a long time, energy saving is mainly achieved by adjusting the chilled water system. The temperature in northern China is low all the year round and has a long-term and stable external cold source, so there are more refrigeration methods that can be used. the most commonly used refrigeration methods are indirect natural cooling and direct natural cooling, that is, the use of external natural cold sources to greatly reduce the refrigeration energy consumption of the data center.

In terms of product applications, two different development directions of data centers lead to different ways of refrigeration. Telecom operators prefer large computer rooms, large systems and large equipment, so they require more single refrigeration power of air-conditioning equipment. In the past, chilled water systems with refrigeration capacity below 150kW can no longer meet their needs, and refrigeration units with larger cooling capacity are widely used in telecom operators' data centers. There are also some enterprise private data centers whose business development is uncertain, so they prefer to adopt a modular data center deployment approach. These modular data centers are usually equipped with inter-column air conditioners, and inter-column chilled water air conditioners with cooling capacity below 30kW are more popular.

Improve refrigeration efficiency and reduce energy consumption

As the only enterprise listed in China in the precision air-conditioning industry, Yimikang has always attached importance to technological innovation and product upgrading. In addition to continuously optimizing the energy efficiency of individual refrigeration equipment, Yimikang has always been committed to technological innovation and development, leading technological change in the data center. Yimikang also vigorously promotes market development, adopts flexible sales strategies and actively expands market share.

Yimikang launched a variety of new products to meet the needs of users: for chilled water units with high water temperature and high return air temperature, Imikang re-optimized the high temperature design of traditional chilled water precision air conditioners and launched sunken EC fans to improve refrigeration efficiency; in terms of direct natural cooling, Imikang launched SNE series fresh air wet film units. In terms of indirect natural cooling, Yimikang launched dual-power fluorine pump cycle precision air-conditioning equipment, the use of external cold sources to reduce refrigeration energy consumption and improve the efficiency of the computer room.

Imikang has also partnered with telecom operator IDC to launch large chilled water units with 200kW refrigerating capacity to meet the application of large computer rooms, as well as with ZTE, Huawei and Tencent to promote the application of SC.I series inter-row air conditioning units in modular data centers. Yimikang also combines its refrigeration scheme with the environmental monitoring products of the company's Dragon Control Company to realize the control and control of the energy in the computer room.

Achieve comprehensive energy efficiency management

In terms of management, the data center infrastructure management (DCIM) platform has been widely concerned by data center users. DCIM platform can effectively use the refrigeration equipment of the data center, accurately monitor the changes of the environment in the data center, and adjust it timely and accurately, which plays a very important role in improving the efficiency of the data center and reducing the PUE value of the data center.

Imicon is not only a sophisticated environmental integrated solution service provider, but also an energy efficiency management expert in data centers. Yimikang takes improving the comprehensive operation and management ability of the data center as its own responsibility, attaches importance to the comprehensive performance management of the data center, and aims to improve the monitoring and management level of the power environment of the computer room. Imikang's DCIM management platform is an ECO energy efficiency management system, which can reduce the cost of energy use through efficient energy management and energy consumption analysis, and monitor and manage the overall temperature environment of the computer room to ensure that the computer room is in a state of low energy consumption. Imicon's refrigeration system can be seamlessly integrated with the DCIM management platform and can be integrated with third-party equipment, making it an ideal choice for user energy management.
