Engineering Contradiction Analysis
1Reliability
If conventional adiabatic cooling systems are used, then cooling efficiency is maintained, but water consumption increases significantly
Solution Approach 1:
The system performs adiabatic pre-cooling of air before it enters the heat exchanger coils, using adiabatic panels positioned in the air inlet path. This preliminary cooling action reduces the thermal load on the main cooling system, allowing for reduced water consumption in the adiabatic cooling process while maintaining overall cooling efficiency.
Solution Approach 2:
The adiabatic panels are strategically positioned only in the air inlet areas where pre-cooling is most effective, rather than cooling the entire air flow uniformly. This localized approach optimizes water usage by applying adiabatic cooling only where it provides maximum benefit to the incoming air stream.
2Loss of substance
If sensor and control systems are added to reduce water consumption, then water consumption decreases, but system complexity increases
Solution Approach 1:
The system utilizes the natural adiabatic cooling effect of water evaporation on adiabatic panels, which automatically cools incoming air without requiring external control systems. The physics-based mechanism self-regulates the cooling process, eliminating the need for complex sensors and controllers while maintaining effective water consumption reduction.
3Reliability
If adiabatic cooling systems operate continuously, then cooling effectiveness is maintained, but energy consumption increases
Solution Approach 1:
By pre-cooling air using adiabatic panels before it enters the heat exchanger, the system reduces the energy required by the main cooling system to achieve the desired cooling effect. This preliminary action allows the main cooling system to operate more efficiently, reducing overall energy consumption while maintaining cooling effectiveness.
Solution Approach 2:
The system changes the temperature parameter of the incoming air stream through adiabatic pre-cooling, lowering it before it enters the heat exchanger. This parameter change reduces the thermal load on the main cooling system, enabling it to operate with lower energy consumption while maintaining the required cooling effectiveness.
