Engineering Contradiction Analysis
1Loss of energy
If current cooling system designs focus on minimizing temperature and maximizing cooling airflow efficiency, then energy consumption is reduced, but exergy loss remains suboptimal and environmental sustainability is not fully achieved
Solution Approach 1:
The patent applies parameter changes by transitioning from traditional temperature-based cooling optimization to exergy-based optimization. The synthesizer evaluates multiple candidate system designs by calculating exergy loss values for each configuration and selects designs that meet exergy loss target values, thereby fundamentally changing the optimization parameter from temperature to exergy efficiency
Solution Approach 2:
The patent replaces traditional trial-and-error or rule-based cooling system design methods with a computational synthesizer that uses thermodynamic exergy calculations. This substitution of the design methodology enables systematic optimization of exergy loss without proportionally increasing design complexity
2Temperature
If data centers increase cooling system capacity to handle heat dissipation, then temperature control is improved, but energy consumption and environmental impact increase
Solution Approach 1:
The synthesizer implements feedback by calculating exergy loss values for candidate system designs and comparing them against exergy loss target values. This feedback loop enables iterative optimization where system configurations are evaluated and refined based on their thermodynamic efficiency performance
Solution Approach 2:
The patent applies dynamics by enabling the cooling system design to adapt to different exergy loss targets and operational conditions. The synthesizer can evaluate multiple candidate designs with varying configurations, allowing the system to dynamically select optimal designs based on specific exergy loss requirements rather than using fixed design parameters

AI summary
In a method of synthesizing components to design a system meeting an exergy loss target value, one or more candidate sets of components are synthesized and an exergy loss value for each of the one or more candidate sets of components are calculated. A determination as to whether at least one of the candidate set of components meets the exergy loss target value is made and at least one candidate set of components determined to meet the exergy loss target value is identified as the set of components for use in the design of the system.
