DC Energy Storage Systems

Data Center Emergency Cooling Study

Active Power recently commissioned Opengate Data Systems, a Massachusetts based engineering firm to examine the impact of a power outage in a data center environment and the subsequent loss of cooling. In the event of a power disruption, the ambient temperature can rapidly increase since a power outage will usually force the data center’s cooling system to shutdown. It typically takes two to three minutes before full cooling capacity is restored and all cooling systems cycle back on. Active Power’s CoolAir technology was also reviewed for its performance during power disruptions and its ability to solve these thermal overload conditions. To access the full study, click here.

TACAS Technology

The CoolAir DC stores energy in the form of compressed air and heat. During a utility outage, the compressed air is routed through a Thermal Storage Unit (TSU) to acquire heat energy. The heated air spins a simple turbine/alternator to produce electric power. The CoolAir DC also contains a small, continuous-duty flywheel to support the critical load during the brief period required for the turbine to spin up to speed.
