Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If multiple air-conditioning devices are used in the containerized data system, then the cooling capacity is improved, but the device complexity increases
Solution Approach 1:
The containerized data system is divided into multiple independent ventilation zones, each served by separate air-conditioning devices with independent ventilation ducts. This segmentation allows each device to handle specific regional cooling requirements, improving overall heat dissipation performance while maintaining manageable complexity through modular design
Solution Approach 2:
The air-conditioning devices are designed with mutual takeover capability, where each device can serve multiple functions: cooling its designated zone normally, and assisting to cool other zones when another device fails. This multi-functionality improves temperature control reliability without requiring additional dedicated backup equipment
2Reliability
If independent ventilation ducts are used for each air-conditioning device, then the system reliability is improved through mutual takeover capability, but the heat dissipation efficiency deteriorates when one device fails
Solution Approach 1:
The ventilation duct system incorporates dynamic flow control mechanisms that automatically adjust air flow distribution when one air-conditioning device fails. The system dynamically reallocates cooling capacity from operational devices to affected zones, maintaining heat dissipation efficiency while preserving reliability through mutual takeover capability
3Productivity
If high-density computing devices are deployed in the containerized data system, then the productivity is improved, but the heat generation increases leading to temperature control issues
Solution Approach 1:
Multiple air-conditioning devices with independent ventilation ducts serve as intermediary cooling systems between the high-density computing devices and the container environment. These intermediary cooling systems efficiently transfer and dissipate heat energy generated by computing devices, enabling high productivity while maintaining acceptable temperature levels
