CPP Data Center Webinar #2 – Thermal Assessments for Hyperscale Data Centers Due to Re-entrainment of Heated Exhaust Sources

Rendering of a typical Hyperscale Data Center in one of CPP’s atmospheric boundary layer wind tunnels. Physical dispersion modeling is used to define the level of re-entrainment of exhaust at nearby air intakes.

Mission Critical Data Centers can have up to 100 times the power density of an office building.

This is due to several factors, including the high plug loads of the servers, the level of heat rejection required within the server rooms, and the 24/7/365 operation of these facilities.

Over 30% of the power consumption in the Data Center can be attributed to the HVAC system (LBNL, 2007), with its primary purpose of maintaining acceptable thermal environment within the server rooms, by rejecting the heat from the hot isles (fan energy) and supplying chilled air to the cold isles (fan energy and cooling loads).

WEBINAR #2 TOPIC: Thermal Assessments for Hyperscale Data Centers Due to Re-entrainment of Heated Exhaust Sources
DATES: Tuesday, Oct. 20th @ 8:30 a.m.
Thursday, Oct. 22nd @ 4:30 p.m.

Points to be addressed:

  • To minimize energy consumption, most new data centers are designed to take advantage of free-cooling techniques
  • Energy models, used to aid in the design of the facility, often utilize long term temperature data from nearby meteorological stations, typically from nearby airports. Site-specific design wind speeds that account for complex terrain, thunderstorms, tornados, and/or hurricanes
  • The adverse effects, of even small increases in the intake temperatures, due to exhaust re-entrainment
  • The correct way to analyze the reliability impact of economization is to use climate data to construct a time-weighted average x-factor

CPP can help bring the proven science of Wind Engineering to the design and operation of your Hyperscale Data Centers.
