Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If conventional cooling systems are used for data centers, then cooling function is provided, but energy saving effect is poor and stability is insufficient
Solution Approach 1:
The system divides outdoor heat exchange modules into multiple independent units that can operate independently. Each module includes a compressor, condensing device, and associated controls, allowing the system to segment cooling capacity into discrete, manageable units that can be individually optimized for energy efficiency and reliability.
Solution Approach 2:
The system dynamically adjusts the number of outdoor heat exchange modules operating in active mode based on real-time cooling demands. The control system monitors cooling requirements and automatically switches modules between active and standby modes, optimizing energy consumption while maintaining sufficient cooling capacity and system stability.
2Reliability
If outdoor heat exchange modules are switched between active and standby modes, then cooling capacity is maintained, but system complexity increases
Solution Approach 1:
Outdoor heat exchange modules are pre-configured in standby mode with compressors already running, so they can immediately transition to active mode when needed. This preliminary preparation eliminates startup delays and ensures continuous cooling capacity without requiring complex real-time activation sequences.
Solution Approach 2:
Multiple outdoor heat exchange modules are designed as identical, interchangeable units. Each module is a complete copy with the same compressor, condensing device, and control system, simplifying the switching mechanism as modules can be freely substituted without complex reconfiguration or adaptation.
3Use of energy by moving object
If compressors are stopped in standby mode, then energy consumption is reduced, but startup delays occur when switching to active mode
Solution Approach 1:
Compressors in standby mode outdoor heat exchange modules are kept running continuously rather than being stopped. This preliminary action ensures that when a standby module needs to switch to active mode, the compressor is already operational and can immediately provide cooling capacity without any startup delay.
Solution Approach 2:
The compressors in standby modules maintain continuous operation, ensuring that the useful action of compression is never interrupted. This continuous operation eliminates gaps in cooling capacity and ensures seamless transition between active and standby modes, maintaining 100% cooling capacity availability.
