The range of HVAC design options associated with the various types of data centers has expanded and evolved over the past 30 years in order to keep pace with the wide array of server transformations and deployment strategies. With the extensive variations of HVAC equipment, control strategies, and system applications, there are almost unlimited options for the design engineer, or the facility engineer, to consider when expanding, renovating, or building from the ground up. A common thread in our design strategies is the implementation of variable air volume components and sequences into the new or renovated systems. The VAV strategies are coupled with other variable water-flow designs and variable-temperature sequences for a comprehensive approach.
With the increasing emphasis on energy management in conjunction with the ever-present uptime requirements, designers should take advantage of the numerous opportunities that variable air volume systems can offer the building owner or operator.
