The Guide Every Datacom Professional Needs

Data center rack heat loads are steadily climbing, and the ability for many data centers to deliver either adequate airflow rates or chilled air is now being stretched to the limit to avoid decreased equipment availability, wasted floor space, and inefficient cooling system operation. This situation is creating a need for liquid cooling solutions to reduce the volume of airflow needed by the racks and for lower processor temperatures for better computer performance. This book provides cooling system designers, data center operators, equipment manufacturers, chief information officers (CIOs), and IT specialists with best practice guidance for implementing liquid cooling systems in data centers.

This second edition includes updated references and further information on approach temperatures and liquid immersion cooling, plus guidance on water quality problems and wetted material requirements. It also includes definitions for liquid and air cooling as they apply to the IT equipment, along with an overview of chilled-water and condenser water systems and other datacom equipment cooling options. The book also bridges the liquid cooling systems by providing guidelines on interface requirements between the chilled-water system and the technology cooling system and on the requirements of liquid-cooled systems that attach to a datacom electronics rack to aid in data center thermal management.

This book is the fourth in the ASHRAE Datacom Series, authored by ASHRAE Technical Committee 9.9, Mission Critical Facilities, Data Centers, Technology Spaces and Electronic Equipment. This series provides comprehensive treatment of datacom cooling and related subjects.
