The following is a detailed introduction to the relevant details of the rubber joint contract for the IDC HVAC project of Tianjin Gaocun Qingshu Science Park.

I. Details of the IDC HVAC Project of Tianjin Gaocun Qingshu Science Park
The waste – heat utilization and energy – supply project of the data center of Jingjin Gaocun Qingshu Science Park (hereinafter referred to as “Qingshu Science Park”), invested and constructed by State Grid (Tianjin) Integrated Energy Service Co., Ltd., has officially commenced construction. According to professional estimates, upon completion, the project can save approximately 1.09 million kWh of energy consumption for the data center each year.
Qingshu Science Park is located in Gaocun Science and Technology Innovation Park between Beijing and Tianjin. This park is a crucial part of the Beijing – Tianjin – Hebei Big Data Comprehensive Pilot Zone, attracting the settlement of over 10 big – data – related enterprises, such as China Telecom, Global Switch, China Railway, and Huawei. The project under construction will build an energy station with an area of approximately 800 square meters within Qingshu Science Park.
Yang Yanchun, the deputy manager of the Market Operation Department of State Grid (Tianjin) Integrated Energy Service Co., Ltd., introduced: “This energy station focuses on collecting the waste heat generated by the data center, supplemented by air – source heat pump and electric refrigeration unit technologies. By applying advanced magnetic – levitation heat – pump technology and a configured intelligent energy management system, it enables the efficient and optimized matching operation of equipment such as mainframes, water pumps, and cooling towers in the data center. After the project is put into operation, it can provide winter heating, summer cooling, and domestic hot water supply services to buildings in Qingshu Science Park with an area of over 100,000 square meters. It is estimated that the annual energy cost can be reduced by approximately 1 million yuan, and carbon dioxide emissions can be decreased by 1,659 tons.
In the entire HVAC system, the rubber joints, spring shock absorbers, and rubber compensators provided by Shanghai Songjiang Group play a vital role.
Performance of Rubber Joints
Our rubber joints are meticulously crafted from top – grade synthetic rubber materials through advanced manufacturing processes, endowing them with excellent comprehensive performance.
In terms of chemical corrosion resistance, they demonstrate strong tolerance to various chemical media commonly found in HVAC systems, such as acid – base solutions and coolants. They can effectively resist chemical erosion, ensuring long – term and stable operation in complex chemical environments and significantly extending their service life.
Their high – temperature resistance is equally remarkable. They can withstand a high – temperature environment of [X] °C. Even under extreme high – temperature working conditions, the physical and chemical stability of the rubber joints remains in good condition. They will not soften, deform, or experience performance degradation due to high temperatures, ensuring reliable operation in high – temperature areas.
Regarding displacement compensation capabilities, the rubber joints feature a sophisticated design, enabling them to flexibly handle axial, lateral, and angular displacement changes. In the face of axial expansion and contraction of pipelines caused by thermal expansion and contraction, they can provide an expansion and contraction compensation of up to [X] mm. For lateral displacements resulting from equipment vibrations or installation deviations, they can effectively absorb an offset of [X] mm. In terms of angular displacement, they can adapt to an angular change of [X] °. This powerful displacement compensation ability greatly alleviates stress concentration in the pipeline system caused by displacements, comprehensively safeguarding the structural safety and sealing performance of the pipeline system.
In addition, the internal structure of the rubber joints has been optimized. With a smooth inner lining and a rational flow – path layout, the resistance of the fluid passing through is minimized. Compared with similar products, the flow resistance is reduced by [X]%, significantly improving the fluid transportation efficiency of the HVAC system and reducing energy consumption. Meanwhile, their sealing performance is outstanding. Using special sealing processes and materials, they ensure zero leakage within the operating pressure range of the system, effectively maintaining the stable operation of the system.
The spring shock absorbers, with their excellent shock – isolation properties, significantly reduce the transmission of vibrations generated during equipment operation to the underlying structure, minimizing the impact of vibrations on the surrounding environment. This creates a stable operating environment for the precision equipment in the data center and reduces noise interference, ensuring a comfortable working and living environment for the personnel in the park. The rubber compensators further enhance the ability of the pipeline system to cope with various complex working conditions. They can absorb the axial, lateral, and angular displacements of the pipeline, effectively relieving the stress caused by factors such as thermal expansion and contraction, and terrain changes, ensuring the safety and stability of the entire system.”
In the pre – construction phase of the project, State Grid Tianjin Wuqing Company actively carried out park – visiting work, vigorously promoted knowledge of energy conservation and consumption reduction, and gained an in – depth understanding that Qingshu Science Park had demands for cooling and heating, and there was a large amount of waste heat in the surrounding data centers awaiting utilization, with great potential for recovery and conversion. Based on the actual energy – usage requirements of the park, State Grid (Tianjin) Integrated Energy Service Co., Ltd. conducted comprehensive on – site inspections and technical analyses, and meticulously formulated a comprehensive energy – saving renovation plan. The construction of this project adopts innovative technologies such as multi – level active and passive system protection, which require extremely high construction techniques and a tight schedule.
To ensure the high – quality and on – time commissioning of the project, State Grid (Tianjin) Integrated Energy Service Co., Ltd. carefully arranged the construction schedule in reverse, strictly controlled key aspects such as plan confirmation, drawing review, and safety supervision, ensuring the orderly progress of the project according to the nodes. Especially in the installation of rubber joints, spring shock absorbers, and rubber compensators, professional technicians were arranged to provide guidance and supervision to ensure precise installation positions and high – standard installation techniques, enabling them to fully exert their key functions in the system.
At present, more and more data center projects are taking root in Tianjin. Focusing on the recoverable waste – heat resources in data centers, State Grid Tianjin Electric Power will continue to closely engage with project construction, deeply explore the potential for energy conservation and consumption reduction, and continuously explore the implementation paths for diversified and clean energy supply, as well as efficient and electrified energy consumption, fully contributing to the achievement of the “dual – carbon” goal. As a professional rubber compensator supplier, Shanghai Songjiang Group will also rely on its high – quality rubber joints, spring shock absorbers, and rubber compensators to continuously provide strong support for the stable operation of the HVAC systems in various projects.
