Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Data centers face challenges in managing temperature and humidity conditions to ensure that IT equipment transitions smoothly into operational states without damage, as existing systems often fail to maintain specified environmental specifications, leading to potential equipment damage or reduced service life.
Innovation Solution
A management system that monitors interior air temperature and humidity, adjusts the temperature set point of supply air to match specified ranges for individual IT components, and triggers their operational states only when these conditions are met, using a controller and environmental subsystem to manage cooling and heating.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the data center maintains a fixed temperature range for existing IT equipment, then the existing equipment operates reliably, but additional IT equipment with different temperature requirements cannot be activated
Solution Approach 1:
The patent implements dynamic temperature setpoint adjustment by the environmental subsystem. Instead of maintaining a fixed temperature range, the system can dynamically change the temperature setpoint to match the requirements of different IT equipment being activated. This allows the data center to adapt environmental conditions for various equipment types while maintaining reliability through controlled transitions.
Solution Approach 2:
The system changes the temperature parameter of the environmental conditions to accommodate different IT equipment requirements. By adjusting the temperature setpoint based on the specific equipment being activated, the system enables versatility in supporting multiple equipment types while managing the transition carefully to maintain reliability.
2Productivity
If the environmental subsystem starts up before IT equipment is ready, then the environmental system is operational, but IT equipment may be damaged by unsuitable temperature conditions
Solution Approach 1:
The patent implements preliminary coordination between the environmental subsystem and IT equipment startup processes. The system prepares environmental conditions in advance and monitors equipment readiness, ensuring that temperature conditions are suitable before equipment activation. This preliminary action prevents equipment damage while maintaining productivity by having the environmental system ready when needed.
Solution Approach 2:
The system uses feedback mechanisms to monitor both environmental conditions and IT equipment status. This feedback allows the system to coordinate startup sequences properly, ensuring equipment is only activated when environmental conditions are appropriate, thus protecting equipment while maintaining operational readiness.
3Loss of time
If the data center allows rapid temperature changes to quickly activate new equipment, then equipment activation is faster, but thermal expansion/contraction damage may occur
Solution Approach 1:
The patent implements controlled, periodic temperature adjustments rather than rapid single-step changes. The environmental subsystem makes gradual temperature modifications over time, allowing equipment to adapt thermally without suffering expansion/contraction damage. This periodic action reduces the harmful thermal effects while still enabling equipment activation in a reasonable timeframe.
Solution Approach 2:
The system applies beforehand cushioning by implementing controlled temperature transition rates. Before activating new equipment, the system prepares the thermal environment with gradual temperature changes that cushion against thermal shock, preventing damage from rapid thermal expansion or contraction while still achieving timely equipment activation.

AI summary
A management system controls environmental conditions to facilitate operating state changes of individual information technology (IT) equipment within a data center. A management controller accesses a specification data structure containing environmental conditions specified to enable each one of the IT components to function in operational operating state(s). The management controller determines a temperature range specified in the specification data structure for a first IT component that is scheduled to transition into a first operational state. The management controller adjusts a temperature set point of supply air provided by the data center to the first IT component to be within the temperature range. In response to determining that the interior air temperature is within the temperature range, the management controller triggers activation of the first IT component into the first operating state.
