Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple types of cooling equipment are combined for operation, then cooling efficiency is enhanced, but equipment costs and space occupation increase
Solution Approach 1:
The plate evaporator is designed to serve dual functions: it can operate as part of a refrigerant-based cooling circuit (first medium circuit) or as a heat exchanger with cooling water (second medium circuit). This multi-functionality allows a single piece of equipment to adapt to different cooling scenarios, eliminating the need for multiple specialized cooling devices and thereby reducing equipment costs and space occupation while maintaining enhanced cooling efficiency.
Solution Approach 2:
The system incorporates dynamic switching capability between two different medium circuits through a control device. The plate evaporator can dynamically transition between operating with refrigerant medium and operating with cooling water based on real-time cooling demands and resource availability. This dynamic adaptability enables the system to optimize cooling efficiency for different scenarios without requiring fixed multiple cooling equipment configurations.
2Productivity
If cooling equipment is tailored to specific application scenarios, then cooling performance is optimized, but adaptability across diverse scenarios decreases
Solution Approach 1:
The plate evaporator is designed as a universal heat exchange component that can function in both refrigerant-based and water-based cooling systems. This multi-functional design enables the equipment to maintain optimized cooling performance across diverse application scenarios without requiring scenario-specific customization, thereby achieving both high cooling performance and broad adaptability.
Solution Approach 2:
The system changes the type of cooling medium (refrigerant or cooling water) based on the application scenario and resource availability. By dynamically adjusting the medium parameter, the system maintains optimized cooling performance for different thermal loads and environmental conditions while preserving adaptability across diverse scenarios.
3Productivity
If refrigerant medium is used for heat exchange, then cooling efficiency is improved, but system complexity and cost increase
Solution Approach 1:
The system dynamically selects between refrigerant-based and water-based cooling modes based on real-time conditions such as thermal load requirements and resource availability. The control device manages the switching between the first medium circuit (refrigerant) and the second medium circuit (cooling water), allowing the system to achieve high cooling efficiency when refrigerant is needed while avoiding unnecessary complexity when cooling water suffices.
Solution Approach 2:
The system changes the cooling medium parameter from refrigerant to cooling water (or vice versa) based on operational requirements. This parameter change allows the system to achieve improved cooling efficiency when high-performance refrigerant cooling is required, while reducing system complexity and cost by using simpler water-based cooling when appropriate.
