How EE’s Wireless Sensors Help Customers Track Performance

Enabled Energy recently completed a successful deployment of its second-generation wireless space temperature sensors at a telecommunication’s central office in Utah.  The facility is a large data center that supports a critical load of about 455kW.  38 wireless space temperature sensors were deployed along with two wireless network gateways to augment an existing array of 230 wireless space temperature sensors in the facility.  The sensors were installed in a configuration of one sensor for every three active equipment racks in the cold aisles and one sensor for every five active racks per hot aisle which aligns with ASHRAE standards.

The sensor data is networked through the wireless gateways to Niagara-based controllers that communicate the data to an Enabled Energy ClaritEE™ energy management system.  The ClaritEE™ system graphically represents the temperature data and generates real-time heat maps for the data center.  The data is also used by the ClaritEE™ system to calculate a rack cooling index (RCI) metric for each room in the data center.  A trending tool within the ClaritEE™ system collects temperature data and creates charts for tracking temperature data from any sensor(s) over time.  The ClaritEE™ system supports alarm features for the temperature sensors that notify users of high or low temperatures, low battery life, and lost communication.  Interestingly, the ClaritEE™ system shows the temperature sensors in the existing array still have approximately 88% of their battery life remaining despite being deployed over a year and a half ago!

This customer is looking forward to utilizing the temperature sensor data and analytics to optimize air conditioning in the space so as to reduce energy consumption and improve overall PUE of the facility.  They also intend to leverage the ClaritEE™ system for ongoing local and remote diagnostics for ongoing operations and maintenance needs.
