AI Technical Summary

Technical Problem

In data center server rooms, the airflow from multiple air conditioning units often clashes in specific areas, creating a high-energy static pressure aerodynamic lock-up. This makes it difficult to eliminate local hotspots, and traditional strategies such as increasing airflow or pressurization only exacerbate the airflow clash, creating a vicious cycle.

Method used

By actively identifying high-energy static pressure aerodynamic deadlock states, using airflow gain testing and supply air aerodynamic load parameters, the coupled interference unit is locked, and an asymmetric pressure gradient field is constructed to force the airflow to deflect into the target cabinet area, breaking the airflow stagnation.

Benefits of technology

It effectively eliminates local hot spots, reduces system deployment and maintenance costs, achieves stability and robustness of the temperature field, and avoids the risk of secondary overheating.

Abstract

This application relates to the technical field of temperature field control, and in particular to a method and system for intelligent temperature field control in data center server rooms. It includes responding to an excessive inlet air temperature in a target rack area by performing an airflow gain test. If the test feedback shows that improving the inlet air temperature is ineffective and the air supply aerodynamic load parameters exhibit non-linear growth characteristics, the area is determined to be in a high-energy static pressure aerodynamic deadlock state. In this high-energy static pressure aerodynamic deadlock state, a deceleration perturbation test is performed on adjacent units, locking the units whose deceleration action causes a drop in inlet air temperature as coupled interference units. The main control unit is controlled to maintain an air supply state establishing a positive momentum advantage, while simultaneously forcing the coupled interference units to perform a forced deceleration action to construct a lateral low-pressure guiding zone, tangentially deflecting the deadlocked airflow into the target rack area. This application can construct an asymmetric pressure gradient to break the high-energy static pressure aerodynamic deadlock, forcibly deflecting the airflow into the rack to eliminate hotspots.
