Movable Partition Climate Control for Zoned Server Room Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing climate control systems in electronic equipment rooms are inefficient as they often require maintaining the entire room at the lowest temperature required by any piece of equipment, leading to excessive energy and cost consumption, and may not suit the cooling needs of all equipment effectively.
Innovation Solution
A climate control system that divides an electronic equipment room into subchambers with movable partitions and separate HVAC units, allowing for different levels of cooling in each subchamber based on the specific thermal requirements of the equipment, with a system controller managing the partition movement and cooling levels dynamically.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the entire room is climate controlled to the lowest temperature required by any single piece of equipment, then all equipment is protected from overheating, but energy consumption and cost increase significantly
Solution Approach 1:
The patent divides the electronic equipment room into multiple temperature zones using movable partitions and separate HVAC units. Each zone can be independently controlled to match the specific cooling requirements of equipment within it, eliminating the need to cool the entire room to the lowest temperature requirement. This segmentation resolves the contradiction by maintaining reliable cooling for all equipment while significantly reducing energy consumption through localized temperature control.
Solution Approach 2:
The system implements different temperature conditions in different spatial locations based on the specific thermal requirements of equipment in each area. High-heat-generating equipment receives intensive cooling in dedicated zones, while heat-sensitive equipment receives appropriate cooling in separate zones. This local quality approach ensures each piece of equipment receives the exact cooling it needs without wasting energy on over-cooling other areas.
2Reliability
If the entire room is climate controlled to the lowest temperature required by any single piece of equipment, then cooling coverage is maximized, but cost increases
Solution Approach 1:
By segmenting the room into multiple independently controlled temperature zones, the system ensures comprehensive cooling coverage for all equipment types while avoiding energy waste. Each zone's HVAC unit operates only when and where needed, eliminating the energy waste associated with maintaining low temperatures in areas that don't require them.
Solution Approach 2:
The system applies cooling action only to the extent necessary for each specific zone rather than applying uniform excessive cooling throughout the entire room. Each HVAC unit provides partial cooling action localized to its designated zone, achieving sufficient cooling coverage without the energy waste of over-cooling.
3Use of energy by moving object
If movable partitions are used to create subchambers with different cooling levels, then energy efficiency improves, but system complexity increases
Solution Approach 1:
The use of movable partitions to create separate controllable zones directly enables energy efficiency improvements, with the system complexity being a necessary trade-off for achieving zoned temperature control and the associated energy savings.
Solution Approach 2:
The movable partitions provide dynamic reconfiguration capability, allowing the system to adapt to changing equipment arrangements and cooling requirements. This dynamic element enables the system to maintain optimal energy efficiency while accommodating various operational scenarios, justifying the increased complexity through enhanced flexibility and adaptability.

AI summary
A climate control system may include an electronic equipment room including one or more interior partitions dividing the chamber into two or more subchambers. The system may further include a cooling system configured to provide the subchambers with different levels of cooling, wherein at least one partition is movable from a first position defining a first subchamber to a second position defining a second subchamber in a different area of the room than the first subchamber. The system may also include a controller including instructions for controlling operation of the movable partition based on cooling requirements of the electronic equipment in the room; a first heating, ventilation, and air conditioning (HVAC) unit and a second HVAC unit, each configured to provide cooling to a different subchamber of the electronic equipment room; and a third HVAC unit configured to provide backup for the first HVAC unit and/or the second HVAC unit.
