    Abstract: This paper is in English and Chinese languages.

    When one hears the phrase "indoor air quality" or IAQ, most associate this with the health, well-being, and comfort of humans in an occupiable space. However, in mission critical facilities such as data centers, IAQ is being scrutinized less for the human occupants and more for the "health" of the critical informational technology (IT) and datacom equipment.

    Regulatory changes in place since 2006 resulted in much higher failure rates for IT and datacom equipment in facilities located in regions with high air pollution levels. The use of outdoor air for free cooling as a way to reduce energy costs has reached the mainstream of data center design and for many companies it is now the standard design approach for all new facilities. However, as the use of free cooling expands many locations are experiencing higher equipment failure rates due to the effects of gaseous pollutants, higher temperatures, and fluctuating humidity inside the data center.

    This doesn't mean that free cooling should not be considered where feasible; it is just that a few additional steps are required to assure reliable operation of datacom equipment.

    This paper will present:

  • Air quality standards for datacom environments.
  • Updates on ongoing environmental concerns.
  • An overview of free cooling with respect to issues affecting electronic equipment reliability.
  • Free cooling case studies with and without application of contamination assessment, control, and monitoring programs.

  • Key Words: 

    Air quality, corrosion, data center, electronic equipment reliability, free cooling
