Two-Stage Power Delivery Architecture Using Hybrid Converters for Data Centers and Telecommunication Systems

In rack power-chain efficiency calculations, treat the number of stages and each stage's efficiency as separate inputs, and show the benefit of fewer stages at load points (low and high current).

  • End to end, direct conversion from about 110 VAC to 1 VDC peaked at 84.1% efficiency at 50 A and fell to 73.5% at 160 A.

Unraveling the Efficiency, Performance and Sustainability Trade-Offs: Case Study of Liquid Assisted Air Cooling vs Traditional Air Cooling (OCP EMEA Summit 2025)

Distinguish LAAC (no facility water, heat still rejected to room air) from DLC with facility water in the server catalog, and do not reduce air-side cooling load for LAAC racks.

  • CPU, NIC and DC-SCM were cooler; DIMMs ran 3-6 C hotter and SSD/PSU temperatures rose.

Nature (Springer Science and Business Media LLC) 2025

Using life cycle assessment to drive innovation for sustainable cool clouds

Add a cooling-technology comparison calculator that computes annual energy as IT MW x load factor x PUE x 8760 and applies the paper's Table 3 deltas (PUE -3%/-6%, IT capacity +3%/+6%) and Table 4 savings ranges as tagged defaults.

  • Switching to 100% renewable electricity cut GHG by 85-90%, energy demand by 6-7% and blue water by 55-85%; server embodied carbon became more significant.

Valve Regulated Lead Acid Battery Evaluation under Peak Shaving and Frequency Regulation Duty Cycles

When considering VRLA UPS strings for grid services, account for frequency regulation (especially in a low SOC window) degrading batteries much faster than peak shaving, with capacity loss tracking internal resistance rise.

  • Test modules: six-cell C&D SHC 12-200FT lead-carbon AGM VRLA, 172 Ah at the C10 rate to 1.8 V/cell at 25 °C, 60 kg.

Energy saving and carbon footprint effect of waste-heat use in data-centre AHU test laboratories (Veri Merkezi Klima Santrali Test Laboratuvarlarında Atık Isının Kullanımı Yöntemiyle Enerji Tasarrufu ve Karbon Ayak İzine Etkisi)

In the catalogue, add test-standard and witness-test fields for IEC/DC AHUs: ASHRAE 143 rating, tested capacity, factory witness test yes/no.

  • Related standards: ASHRAE 143-2015, EN 308, ISO 14044, ISO 14064-1.

Testing-adjusting-balancing of data centres

In the commissioning module, include a TAB task list per cooling unit and hydronic circuit (design versus measured airflow, water flow, differential pressure, set points).

  • The reported outcome is a 10-25% energy efficiency improvement.

Whitepaper Rittal Liquid Cooling Packages

Catalogue close-coupled coolers by type (inline row, closed-loop rack, rear door, DX rack), rated kW, width, footprint, maximum air delta-T and water/refrigerant inlet temperatures.

  • Hybrid doors come in 10 kW and 20 kW versions and open 130 degrees.
