1Productivity
If traditional cooling systems are used to manage CDU operation, then system simplicity is maintained, but cooling efficiency is insufficient and equipment overheating occurs
Solution Approach 1:
The patent creates a digital twin (virtual copy) of the physical CDU that replicates its thermal behavior and operational parameters. This digital model enables sophisticated simulation and optimization without requiring complex physical modifications to the actual cooling system, thereby improving cooling efficiency while maintaining relative system simplicity.
Solution Approach 2:
The system performs predictive simulations and optimizations in advance using the digital twin before implementing changes to the physical CDU. This preliminary action allows the system to identify optimal cooling strategies and prevent overheating conditions before they occur, improving efficiency without requiring complex real-time response mechanisms.
2Productivity
If real-time monitoring and optimization systems are implemented, then cooling efficiency is improved, but management overhead increases
Solution Approach 1:
The digital twin system automatically monitors CDU parameters, simulates thermal behavior, and generates optimization recommendations without requiring continuous manual intervention. The system serves itself by autonomously analyzing data and providing actionable insights, thereby improving cooling efficiency while minimizing the increase in management overhead.
3Duration of action of stationary object
If predictive maintenance capabilities are added, then equipment lifespan is extended, but system complexity increases
Solution Approach 1:
The digital twin serves as a virtual replica that can be used for predictive maintenance simulations without adding physical complexity to the actual CDU. By performing maintenance predictions and failure mode analyses in the digital domain, the system can extend equipment lifespan through better maintenance planning while avoiding the need for additional physical monitoring hardware or complex modifications to the cooling system.
