Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional humidity control systems in data centers face inefficiencies due to reliance on relative humidity detection at AC unit returns, leading to potential condensation and energy wastage, as they may operate in conflicting modes (humidifying and dehumidifying) within the same areas.
Innovation Solution
Implementing a system with humidity control apparatuses and sensors positioned remotely to detect and adjust moisture levels directly at electronic components, using a controller to optimize humidity control and energy efficiency by varying the humidity levels in airflow supplied to specific zones, thereby maintaining desired environmental conditions and reducing energy consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If humidity control is based on relative humidity detection at AC unit returns, then the AC units can maintain relative humidity levels within a desired range, but certain areas may receive overly cool air leading to condensation formation and AC units may operate in conflicting modes (humidifying and dehumidifying) causing energy inefficiency
Solution Approach 1:
The patent applies local quality by transitioning from centralized humidity control at AC returns to distributed humidity control at multiple locations throughout the data center. Sensors are placed at rack levels and humidity control apparatuses are distributed to locally adjust humidity where needed, allowing different zones to have different humidity conditions optimized for their specific requirements rather than forcing uniform control across the entire facility.
Solution Approach 2:
The patent segments the data center into multiple controlled zones with independent humidity control. Instead of treating the entire data center as a single controlled environment, the system divides it into rack-level or zone-level segments, each with its own sensors and control apparatuses that can operate independently to prevent conflicting humidifying and dehumidifying operations.
2Reliability
If AC units are equipped with humidifier/dehumidifier to control moisture content, then the relative humidity can be maintained within desired range, but the system complexity increases and energy consumption increases due to conflicting operations
Solution Approach 1:
The patent implements self-service by enabling individual rack-level or zone-level units to autonomously control their own humidity conditions. Each equipped unit has its own sensors and control capabilities, allowing it to independently adjust humidity without requiring complex centralized coordination or communication between multiple AC units, thereby reducing overall system complexity.
3Ease of operation
If humidity sensors are positioned at AC unit returns to detect relative humidity, then the control system can regulate moisture content, but the measurement may not accurately reflect actual humidity conditions at electronic components leading to suboptimal control
Solution Approach 1:
The patent applies dimensionality change by moving humidity measurement from the vertical dimension (AC return air) to the horizontal dimension where electronic components actually operate. Sensors are positioned at rack levels or directly near equipment to measure humidity in the actual breathing zone of the electronics, providing accurate representation of conditions affecting the components rather than measuring at a remote location.

Function Achieved in This Case
This approach ensures reliable operation of electronic components by maintaining optimal humidity levels and enhances energy efficiency by preventing unnecessary energy expenditure, as humidity control is tailored to specific zones and coordinated with temperature control to avoid conflicting operations of AC units.
