Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If two independent compressors and two independent refrigeration devices are used, then the refrigeration capacity and functionality are improved, but the cost and device complexity increase
Solution Approach 1:
The patent combines two independent compressors into a single dual-suction compressor that can simultaneously intake refrigerant from two different evaporators. This merging approach maintains the refrigeration capacity of dual-compressor systems while reducing device complexity, cost, and improving system integration by eliminating redundant components and controls
2Device complexity
If a single compressor with series-parallel double evaporators is used, then the device complexity is reduced, but the refrigeration capacity and overall efficiency decrease
Solution Approach 1:
The patent segments the single compressor into two independent suction channels, each capable of independently intaking refrigerant from different evaporators. This segmentation allows the compressor to maintain separate refrigeration circuits with different temperature requirements, thereby preserving high refrigeration capacity while keeping the device structure integrated and simple
3Reliability
If existing refrigeration device designs are used, then technical maturity is maintained, but performance improvement and energy efficiency are bottlenecked
Solution Approach 1:
The patent introduces dynamic control capabilities through diverter valves and control valves that can adjust refrigerant flow distribution in real-time. This allows the system to adapt to different operating conditions and temperature requirements, breaking the performance bottleneck of existing static designs while maintaining reliability through proven refrigeration principles
