121–144 / 339
National Laboratory of the Rockies (formerly NREL) 2026
Use as a reference case for warm-water DLC presets (supply about 24 C, return about 38 C).
Vertiv 2024
Add a TEWI calculation to cooling options (refrigerant GWP, charge kg, leak rate, life years, grid emission factor).
Consulting-Specifying Engineer 2021
Offer integrated-free-cooling chillers as a catalogue option with the free-cooling changeover ambient field.
Consulting-Specifying Engineer 2025
Liquid-loop design rules: check pipe velocity <= 2.1 m/s above 3 in. NPS and TCS supply >= dewpoint + 2 C, and flag incompatible wetted materials.
Schneider Electric 2014
Evaluate hot spots only at rack inlets against the selected ASHRAE class recommended range, not hot-aisle temperatures.
Huawei Digital Power 2025
Import RD 01-21 as parametric AI-hall templates (rack kW, racks per module, module kW, redundancy of fan walls/TMUs/towers, generator and transformer counts) and as golden test cases for capacity math.
Schneider Electric 2015
Accept humidity limits as dew point plus RH in the environmental envelope settings, default to current ASHRAE recommended values rather than the 2011 ones quoted here, and recommend dew-point control mode for multi-CRAC rooms.
Cundall (for Iceotope Technologies) 2021
Catalogue liquid-cooled IT and CDUs with ASHRAE W-class and supply temperature fields, and use these to decide whether compressor cooling can be omitted for the site climate.
IEEE 2012
In liquid-cooling energy calculations, account for glycol concentration (higher pumping power, lower heat transfer) and flow-rate set points, not just supply temperature.
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.
Open Compute Project Foundation 2019
In the monitoring/BMS design module, include a telemetry point list that pulls IT power (Redfish/IPMI) alongside facility meters.
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 2026
In the reliability module, add a resilience-level calculator that compares alternative power/cooling topologies on maintainability, recoverability and vulnerability.
ISO/IEC 2021
In the cooling module, apply class-based redundancy rules (N, N+1, 2N) to cooling plant and distribution.
ISO/IEC 2023
In the cooling module, report CER from the hourly model as heat removed (kWh_th) divided by cooling-system electricity (kWh_e).
ISO/IEC 2022
In the water module, derive WUE (L/kWh_IT) from the hourly cooling model (evaporation, blowdown, humidification) and tag it with its measurement category.
Energies (MDPI AG) 2019
Consider a cabinet-level rear-door heat exchanger as an option that can raise heat dissipation by 56-67% over air cooling; compare oil or water coolant separately on leakage risk and maintenance.
Cundall 2024
When a user selects a cooling topology, show a three-way comparison of energy (PUE), water (WUE) and carbon (CUE using local grid intensity) for the chosen site.
Upsite Technologies blog 2022
Rack and server catalogue entries should carry a delta-T (or airflow per kW) field.
ASHRAE 2016
Link IT equipment airflow and thermal characteristics in the catalog to facility cooling selection.
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).
STULZ 2024
Model the per-rack heat split (liquid %/air %); it drives both CDU and CRAH sizing.
