Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional data center and co-location facility designs face inefficiencies in cooling and wire routing, with air conditioning units not being standardized, accessible, or transportable, leading to suboptimal airflow and maintenance challenges.
Innovation Solution
The design incorporates a building with a false ceiling and modular thermal shields to create a hot air containment chamber, using external air conditioning units that recirculate air efficiently, and a cable and conduit routing system that separates power and data wiring for improved airflow and maintenance access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If air conditioning units are installed inside the facility, then cooling can be provided to the electronics equipment, but the units are not accessible or transportable for repair or replacement
Solution Approach 1:
The air conditioning system is divided into modular units that can be independently accessed and replaced. The false ceiling creates accessible zones above the equipment rows where air conditioning components are positioned, allowing segmentation of the cooling system into serviceable modules without disrupting the entire facility.
Solution Approach 2:
The air conditioning units are positioned in the vertical dimension above the electronics equipment rows (in the plenum space created by the false ceiling), rather than being floor-mounted or wall-mounted. This dimensional relocation provides accessibility while maintaining cooling function.
2Ease of manufacture
If wiring is routed through raised floors, then installation is simplified, but power and data wiring are not systematically separated
Solution Approach 1:
The wiring system is segmented into separate routing paths: power wiring is routed through the raised floor, while data/communications wiring is routed through the false ceiling plenum space. This spatial segmentation eliminates interference between power and data lines while maintaining installation efficiency.
Solution Approach 2:
Instead of routing all wiring through the same medium (raised floor), the system uses two different vertical zones: power wiring in the floor cavity and data wiring in the ceiling plenum, creating systematic separation through dimensional differentiation.
3Use of energy by stationary object
If heat is allowed to accumulate in hot aisles, then cooling load is reduced, but airflow patterns become inefficient
Solution Approach 1:
The air conditioning units are positioned to receive hot air directly from the hot aisles through strategically placed intake openings. This creates a feedback loop where heated air is continuously captured and recirculated through the cooling system, maintaining efficient airflow patterns while managing the heat load.
Solution Approach 2:
The hot aisle configuration naturally channels heated air toward the air conditioning unit intakes, allowing the thermal plumes from equipment to self-organize into efficient flow paths that feed directly into the cooling system without requiring additional active management.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration enhances cooling efficiency by rapidly recirculating air, reducing facility temperatures, and simplifies maintenance by allowing for remote control of airflow and easy access to air conditioning units, while maintaining efficient wire routing and power distribution.
Implementation Method 1
a plurality of air conditioning units disposed in the external area outside the building that each receive heated air, emit cooled air
Implementation Method 2
the thermal shield providing a contiguous wall around the hot air area and defining a warm exhaust channel that traps the heated air within the hot air area and causes substantially all the heated air within the hot air area to rise up within the warm exhaust channel
