1Reliability
If conventional complex computational models are used to optimize heat distribution, then heat distribution optimization is improved, but computational power consumption increases and real-time optimization becomes infeasible
Solution Approach 1:
The patent transforms the complex partial differential equations into simplified algebraic equations by changing the mathematical parameters and assumptions. This allows the thermal model to be solved with minimal computational resources while still providing accurate enough results for real-time cooling optimization in data centers.
Solution Approach 2:
The data center is divided into discrete zones or cells, and the thermal model is applied to each zone independently using simplified algebraic equations. This segmentation allows parallel computation and reduces the overall computational complexity compared to solving a single complex model for the entire data center.
