دانلود کتاب Thermal Guidelines For Data Processing Environments

Thermal Guidelines for Data Processing Environments provides groundbreaking, vendor-neutral information that empowers data center designers, operators, and managers to better determine the impacts of varying design and operation parameters on information technology equipment (ITE). This book covers six primary areas: • Environmental guidelines for air-cooled equipment • New environmental class for high-density air-cooled equipment • Environmental guidelines for liquid-cooled equipment • Facility temperature and humidity measurement • Equipment placement and airflow patterns • Equipment manufacturers’ heat load and airflow requirement reporting Since its first publication in 2004, Thermal Guidelines has enabled HVAC equipment manufacturers and installers, data center designers, and facility operators to find common solutions and standard practices that facilitate ITE interchangeability while preserving industry innovation. This fifth edition features clarified wording throughout, changes due to research on the effects of high relative humidity and gaseous pollutants on the corrosion of ITE, and a new environmental class for high-density server equipment. The book also includes a removable reference card with helpful information for facility managers and others. The reference card may also be accessed online. This book is the first in the ASHRAE Datacom Series, authored by ASHRAE Technical Committee 9.9, Mission Critical Facilities, Data Centers, Technology Spaces and Electronic Equipment. The series provides comprehensive treatment of datacom cooling and related subjects.
