By 2026, data center construction will have fully entered a new cycle driven by computing power. The total national rack capacity is projected to exceed 10 million units; power density per rack is climbing from the standard few kilowatts to 30 kW or higher, and the adoption of liquid cooling technology is accelerating. Amidst these shifts, a long-overlooked reality is coming to the fore: as computing density increases and heat becomes more concentrated, the circulation capacity, energy efficiency, and operational reliability of water-based HVAC systems have become critical factors determining the stable operation of intelligent computing centers.
For large-scale data centers, the water-based HVAC system acts as the “transport” mechanism for the entire cooling cycle. Chilled water must be transported over long distances from the cooling plant to terminal air conditioning units on various floors, while condenser water must continuously carry heat away from the server rooms. If water pumps suffer from insufficient output, efficiency degradation, or operational instability, the cooling chain develops a weak link, thereby threatening the operational safety of the computing equipment.
Kaiquan’s Solution
To address these industry needs, Kaiquan offers a dedicated solution for data center HVAC water systems, centered on its KQW series of large-caliber, single-stage horizontal centrifugal pumps. Designed with a focus on efficiency, installation, reliability, and operating range, this product directly addresses the practical concerns surrounding the construction and operation of modern intelligent computing centers.
✅ High-efficiency direct drive with low transmission loss: The KQW single-stage pump utilizes an extended-shaft direct-drive structure, eliminating the need for traditional couplings and fundamentally removing mechanical transmission losses. Actual testing shows an efficiency improvement of 1% to 3% over conventional pump models. Given the continuous, year-round operation of data centers, this efficiency gain translates directly into electricity cost savings, yielding significant energy-related financial benefits over the project’s lifecycle.
✅ Integrated delivery, cutting installation time by 50%: Eliminating the coupling simplifies the mechanical structure, reduces potential points of failure, and significantly lowers the workload for daily inspection and maintenance. Comprehensive analysis indicates that lifecycle O&M costs can be reduced by over 30%, providing a more robust guarantee for continuous cooling in the server room.
✅ High reliability and low maintenance, reducing O&M costs by over 30%: Addressing the long-distance, high-flow transport requirements of large-scale data center HVAC water systems, Kaiquan offers specialized pumps with flow rates up to 1,500 m³/h and heads of 20–50 meters. These units fully meet the operational demands for long-distance chilled water transport and high-volume cooling water circulation.
Application Site: Shenyang Intelligent Computing Center
The Shenyang Intelligent Computing Center serves as a key hub in the national computing power network layout, requiring a constant temperature and humidity environment for its server rooms year-round, despite the region’s high-latitude, low-temperature climate. Within the project’s central cooling plant, Kaiquan’s KQW large-caliber single-stage pumps handle the core circulation tasks for both the chilled water and cooling water systems.
Even in the low temperatures of a northern winter, the pump units start and stop smoothly, with motors operating free from abnormal vibrations or noise. Variable-frequency control allows for on-demand response to fluctuations in terminal loads, ensuring precise temperature control while dynamically optimizing energy consumption for water supply. The compact pump room layout—facilitated by the integrated delivery of the units—also frees up valuable space for equipment arrangement within the cooling plant.
As the wave of computing power expansion surges forward, HVAC water systems—a critical link in the cooling chain—require hydraulic equipment that is highly efficient, reliable, and adaptable to rapid construction schedules to ensure a solid foundation. Leveraging the KQW series of large-caliber single-stage pumps, Kaiquan integrates capabilities such as direct-coupled high efficiency, rapid integrated installation, and low-maintenance reliability into the data center environment, delivering circulation solutions that stand the test of time and ensure the stable operation of national computing infrastructure.
