2015 ASHRAE Handbook-HVAC Applications, Chapter 19: Data Centers and Telecommunication Facilities
ASHRAE · ASHRAE TC 9.9
The data center chapter of the ASHRAE handbook, covering the Datacom Series books, workload and airflow nomenclature, liquid-cooled equipment definitions and contamination concerns.
On this page
Overview
This document is Chapter 19 of the 2015 edition of the ASHRAE Handbook - HVAC Applications, prepared by TC 9.9. It introduces core design concepts for data centers and telecommunication facilities and briefly describes each book of the Datacom Series. At the time the series comprised 11 books produced by TC 9.9.
The content covers datacom equipment workload, rack and airflow nomenclature, liquid-cooled equipment definitions and contamination concerns. When rack counts are unknown early on, it notes that professional judgement is needed between kilowatts per rack and watts per square metre. Front-to-rear airflow nomenclature has been unchanged since 2004. Gaseous contaminants of concern include H2S, SO2, mercaptans, NOx, chlorine and ozone.
Only metadata from the catalogue and handbook descriptions was used here; the chapter itself was not read.
Key points
- The Datacom Series then comprised 11 books produced by TC 9.9.
- When rack counts are unknown early, professional judgement is needed between kW/rack and W/m2.
- Front-to-rear airflow nomenclature has been unchanged since 2004.
- Gaseous contaminants of concern: H2S, SO2, mercaptans, NOx, chlorine, ozone.
- The chapter covers datacom equipment workload and rack nomenclature.
- Liquid-cooled equipment definitions are included.
Using it in design
- Support both W/m2 and kW/rack modes in early-stage load entry.
- Define equipment airflow direction as front-to-rear consistent with the cold aisle and hot aisle layout.
- On sites with ambient pollution risk, take gaseous contaminants (H2S, SO2 and so on) into account in air filtration and material choices.

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.
- CRACs were set to 21 °C but delivered 23 °C supply, and thermal load was about 65% of cooling capacity, so one CRAC was off.
