Grundfos empowers Asia's largest dynamic ice cooling system, redefining a new model of efficient and green cooling.
Project background
The Hainan Lingshui Li'an International Education Innovation Pilot Zone brings together multiple universities. With the continuous expansion of its total building area, there is an increasing demand for efficient, stable, and environmentally friendly centralized cooling systems. The Phase II project of the Lingshui No. 1 Energy Station was launched in response. With a total construction area of approximate-ly 6,200 square meters and a cooling capacity covering 610,000 square meters, the project adopts a hybrid system combining dual-mode chillers, water storage cooling, and dynamic ice storage cooling. Once completed, it will operate in coordination with Phase I, boosting the total cooling capacity to about 1.46 million square meters - making it Asia's largest dynamic ice cooling system.
Challenges: System upgrades driven by high standards
High project complexity
The large scale of the Pilot Zone, extended construction timeline, and the need for multi-party coordination placed extremely high demands on system reliability and delivery capability.
Balancing energy efficiency and stability
Power investors have imposed strict requirements for both energy-saving standards and operational stability. The system must maintain high efficiency and safety under heavy loads, leaving no room for error.
Significant challenges from dynamic operating conditions
The dynamic ice storage cooling system frequently switches between ice making and ice melting, requiring precise control of pump flow and pressure: Insufficient flow reduces ice making efficiency. Excessive flow increases the risk of ice blockage. Dynamic changes in temperature and concentration necessitate real-time adjustment.
High requirements for operation, maintenance, and service
The project must support easy installation, efficient O&M, and a well-integrated after-sales service system to ensure sustained and stable performance.
Solution: Building an efficient and stable intelligent cooling system
From deep involvement to collaborative implementation
Grundfos was deeply involved from the project's early stages, participating in the formulation of technical specifications to enhance solution compatibility. Through close collaboration among sales, application engineers, factory teams, and control system suppliers, we flexibly adjusted solution configuration to ensure efficient project delivery. This "end-to-end collaborative service mode" laid a solid foundation for the smooth implementation of the project.
Integrated solution
Grundfos provided a comprehensive solution for the project, consisting of 26 sets of LS pumps paired with original Nerene control cabinets. The solution enabled: Coordinated operation of 62 pumps across Phase I and Phase II; Centralized dispatching for the cooling supply; High compatibility between the original control system and equipment; "Multi-pump coordination and unified control not only enhance system stability but also significantly reduce operational complexity."
Intelligent control and dynamic response
Through Grundfos' integrated control system, the following capabilities were achieved: Multi-pump operation with real-time adjustment of flow and pressure; Automatic switching between ice-making and cooling modes; Precisely matching the cooling demands at different time periods. The dynamic ice storage system enabled: Efficient ice production during off-peak nighttime hours; Release of stored cooling capacity during daytime peak periods. This enables "Peak Cut", optimizing grid load and operational costs from the source.
Outcomes: Delivering both energy-saving and environmental benefits
The value of the dynamic ice storage cooling system has been fully demonstrated in the Lingshui project:
Grundfos helps you achieve green transformation
The Lingshui Energy Station project not only ensures the efficient and stable operation of a large-scale centralized cooling system but also provides a replicable and scalable demonstration model for university campuses and integrated energy projects. This model is expected to be implemented in more regions, continuously driving regional energy systems toward an efficient, intelligent, and low-carbon future.
Grundfos will continue to leverage its innovative technologies and system solutions, working hand in hand with partners to explore new pathways for energy conservation and emission reduction, helping cities and industrial parks build a more efficient and sustainable future.
