Schneider Electric 2014
Evaluate hot spots only at rack inlets against the selected ASHRAE class recommended range, not hot-aisle temperatures.
Schneider Electric 2013
Build a retrofit wizard asking aisle arrangement (hot/cold yes/no), raised floor (yes/no, depth), drop-ceiling return (yes/no), rack-top-to-ceiling clearance (mm), columns in rows, overhead cabling and existing cooler type, mapped to one of the six containment types.
Schneider Electric 2011
Add rack catalogue fields for door perforation percentage (warn on glass or below the full-perforation spec), rail width versus cabinet width (warn on a 23 in cabinet with 19 in rails and no side seals) and blanking included.
Buildings (MDPI AG) 2024
If cabinets in the rows nearest the cooling units run hot (high-velocity plenum flow starving the nearest tiles), consider adjustable underfloor deflectors and grille opening adjustment before fan-assisted tiles (18.1% and 4.9% airflow shift).
Vertiv 2020
Use hourly climate data (dry-bulb and wet-bulb) in cooling selection to estimate IEC mode hours.
ISO/IEC 2021
In the cooling module, apply class-based redundancy rules (N, N+1, 2N) to cooling plant and distribution.
Upsite Technologies blog 2022
Rack and server catalogue entries should carry a delta-T (or airflow per kW) field.
Türk Tesisat Mühendisleri Derneği (TTMD) - TTMD Dergisi 2025
Use this case as a reference point for air-cooled, outside-air-assisted designs (PUE 1.2; MLC 0.117 in zone 3A).
Proceedings of the 7th ACM International Conference on Systems for Energy-Efficient Buildings, Cities, and Transportation (ACM) 2020
Include a calibration workflow in the hand-over to operations: import aisle sensor data, mark per-server airflow (and bypass/recirculation) as calibration parameters with priors, and report MAE before and after calibration.
Scientific Reports (Springer Science and Business Media LLC) 2025
In a building-integrated edge data centre, distribute workload to servers so outlet temperatures are as high as possible (within standard limits); recoverable heat rose by up to 17.1% over random distribution.
IEEE Transactions on Sustainable Computing (Institute of Electrical and Electronics Engineers (IEEE)) 2017
In data-centre comparisons, do not use PUE as a cross-facility metric; normalise for IT load, weather and location, or state the same conditions.
Schneider Electric 2011
Auto-place 3 inlet temperature sensors per rack front, 1 humidity sensor per cold aisle, and leak rope around every CRAC/CDU and raised-floor water path.
Motivair 2023
Add RDHx entries to the catalog with nominal kW at the stated water and room conditions, flow limit, fan power and rack size compatibility.
Uptime Institute Journal (Uptime Institute) 2021
Tie the humidity control setting to the contamination class: allow the 70% RH upper limit only when coupon test results are entered and within limits.
U.S. DOE Federal Energy Management Program / National Renewable Energy Laboratory 2012
Offer indirect evaporative cooling and airside economizer options in the cooling selector with climate-driven hours.
Applied Sciences (MDPI AG) 2024
Make hot-aisle back pressure (hot-aisle pressure above cold aisle) a design input in contained aisles; server inlet temperature rises once back pressure reaches the fans' free-delivery point.
Buildings (MDPI AG) 2023
For hot-spot removal, before choosing lower supply temperature or higher airflow outright, compare the COP drop (3.2 to 2.6) and the energy difference (20.1% and 4.2%) with a rack-specific air distribution option.
Batteries (MDPI AG) 2026
Define a designed, buoyancy-driven vent or relief path at the top of a storage cabinet; in a closed cabinet H2 forms a flammable layer under the roof, so control gas and heat build-up.
Applied Sciences (MDPI AG) 2025
In retrofitting an existing raised-floor hall, first close unused rack spaces with blanking panels (alone they cut SHI by 42.61%); containment alone gave little benefit.
Buildings (MDPI AG) 2025
Choose a raised-floor height of at least 600 mm; at 300-500 mm some grilles had reverse (negative) flow and uneven static pressure, and gains levelled off above 800 mm.
Beca 2026
Allow mixed-density zones within one hall, each with its own density assumptions.
Frontiers in Energy Research (Frontiers Media SA) 2023
With active tiles, always seal under-rack gaps; if left open, low pressure at the tile surface pulls hot air in under the rack and worsens the lower servers.
Journal of Thermal Analysis and Calorimetry (Springer Science and Business Media LLC) 2025
Verify two-phase immersion PUE claims so they include the external heat-rejection loop (exchangers, pumps, pipes) and not just tank-level power; the 1.01 figure excludes it.
Schneider Electric 2015
Add rack catalog fields: width (600/750/800 mm), vertical cable channel capacity, roof/base cutouts and a 'networkRack' flag.
