Hejing Awarded EPC General Contract for Semiconductor High-Efficiency Machine Room Project

　　Recently, Hejing Smart Construction (Guangdong) Co., Ltd. won the bid for the EPC general contracting project of an efficient data center for a new semiconductor company in the Greater Bay Area, relying on its professional planning, design, and construction capabilities. The total installed capacity of this project is as high as 10000RT, with the goal of achieving a comprehensive energy efficiency of EER6.0 for the whole year.

　　Under the guidance of the dual carbon target, the concept of green, low-carbon, and reduced energy consumption has become the trend of industry development. As a well-known environmental construction enterprise in China, Hejing Construction has always been committed to providing customers with efficient, energy-saving, and environmentally friendly EPC integrated system solutions for construction projects. This winning bid not only demonstrates the company's professional strength in the field of efficient data center construction, but also further consolidates its comprehensive strength in semiconductor and chip plant environmental engineering construction.

　　This semiconductor company is the earliest enterprise in China to achieve the industrialization of third-generation semiconductor silicon carbide epitaxial chips. While committed to promoting industrial technology innovation and green development, with the continuous expansion of its business and the full promotion of "carbon peak and carbon neutrality", the energy efficiency requirements for newly built factories are also increasing. As an important link in the production process of silicon carbide semiconductor materials, the energy efficiency level of efficient computer rooms directly affects the operating costs and environmental impact of enterprises. Therefore, building an efficient and energy-saving computer room is of great significance for semiconductor enterprises.

　　To ensure the green development of the silicon carbide semiconductor chip field, the Hejing Construction team fully leverages their professional advantages in the service system of "efficient design, efficient construction, and efficient self-control" in the efficient computer room based on industry standards and specifications, as well as the production needs of the owner. Effectively reducing construction costs, operating energy consumption, improving system stability, and assisting owners in achieving their target needs.

　　Firstly, during the deepening design phase of the project, the Hejing Construction project team fully utilized BIM (Building Information Modeling) technology to conduct 3D modeling and simulation analysis of the computer room. We have carried out refined design from high-efficiency hardware equipment, optimized configuration, scientifically reasonable data center layout, pipeline routing, etc., to provide a stable, efficient, and secure operating environment for the owners.

　　Secondly, in terms of system integration, Hejing Construction adopts an independently developed efficient data center integration cloud technology system, which efficiently integrates the cooling, power supply, monitoring and other systems in the data center, achieving intelligent management and remote control of the data center. With advanced energy efficiency control systems and precise measurement systems, real-time monitoring and accurate measurement of energy consumption in the computer room provide strong guarantees for energy conservation and consumption reduction.

　　Based on the actual energy efficiency simulation calculation throughout the year, according to the design of this frequency conversion room scheme, the system energy efficiency of the building's actual operation is calculated hourly through deepening design, BIM optimization, and tapping into system potential of Hejing Construction. The energy consumption and energy efficiency of the entire room throughout the year are obtained, such as the comprehensive energy efficiency ratio EERs of the low-temperature system throughout the year; Annual energy efficiency COP of the unit; The comprehensive energy efficiency ratio (EERs) of the medium temperature system throughout the year; The energy efficiency COP of the unit throughout the year (excluding heat recovery) . Expected to save nearly ten million yuan in electricity bills annually. This achievement not only brings huge economic benefits to the enterprise, but also makes a positive contribution to achieving carbon peak and carbon neutrality goals.

　　Throughout its history, Hejing Construction has relied on more than 20 years of focus on EPC construction of clean rooms and efficient computer rooms, as well as rich market experience and advantages in similar projects. It has successfully built numerous benchmark ultra large and large-scale comprehensive model engineering projects in optics, semiconductors, and chips, such as well-known projects such as Zeiss ZEISS, Jinfu Technology, GAC, and China Electronics CEC, which have won widespread recognition and praise in the market.

　　In the future, Hejing Construction will continue to leverage its industry experience advantages, strive for excellence, focus on the semiconductor industry, continuously promote energy-saving technology innovation, launch more systematic and full process environmental design solutions, and build the company's core competitiveness in various fields, thus providing continuous support for the construction of factory environment in the semiconductor industry.
