Engineering Contradiction Analysis
1Reliability
If autonomous and separate adiabatic and refrigeration cycle cooling systems are used, then each system can operate independently, but the cost, installation time, space occupation, and energy consumption increase significantly
Solution Approach 1:
The patent combines the adiabatic cooling system and refrigeration cycle cooling system into a single integrated unit with common structural components including housing, control systems, and airflow pathways. This merging eliminates the need for separate autonomous installations while maintaining the ability to switch between cooling modes based on environmental conditions, thereby reducing cost, installation time, and space occupation without sacrificing operational reliability
2Temperature
If adiabatic cooling is used with high humidity external air, then cooling effect is reduced, but the system structure becomes more complex to handle the humidity variation
Solution Approach 1:
The patent implements a dynamic control system that automatically switches between adiabatic cooling mode and refrigeration cycle cooling mode based on real-time monitoring of external air temperature and humidity conditions. When external air has high humidity, the system transitions to refrigeration cycle mode, while low humidity conditions trigger adiabatic cooling mode. This dynamic adaptation maintains optimal cooling efficiency across varying environmental conditions without requiring complex structural modifications
3Temperature
If refrigeration cycle cooling system is used continuously, then stable cooling is achieved, but energy consumption increases significantly
Solution Approach 1:
The patent employs periodic action by alternating between adiabatic cooling operation and refrigeration cycle cooling operation based on environmental conditions. The system utilizes adiabatic cooling during periods when external air has favorable low humidity conditions, and switches to refrigeration cycle during periods of high humidity. This periodic switching between cooling methods reduces overall energy consumption while maintaining stable cooling performance through automated control
