New AUDIT-BUDDY™ Delta T package now allows data center operators to track and monitor rack-level delta-T to evaluate cooling efficiency
NORTH GRAFTON, Mass.–(BUSINESS WIRE)–Purkay Labs, a leading provider of portable air quality monitors, announced today that it has added rack-level delta-T monitoring to AUDIT-BUDDY™, the first standalone temperature and humidity monitor for the white space.
“At the end of the day, the easiest way to reduce a data center’s electricity costs is to improve the cooling efficiency”
In the past, measurement of server delta-T has proven difficult. Now, users can take two AUDIT-BUDDY™ systems, one in the cold aisle and the other across the selected server in the hot aisle, to track the server delta-T and measure the cooling dynamics at the rack.
The average data center loses a significant amount of cold air due to bypass and recirculation airflow. While the natural response is to “overcool” the hall, cold air loss is not a problem with cooling capacity, but rather poor airflow management.
By comparing the delta-T at the HVAC (supply-return air temperature) to the delta-T at the server (inlet-outlet air temperature), data center managers can determine if they are cooling efficiently or inefficiently. The AUDIT-BUDDY Delta-T Package gives the data center manager the necessary information to determine exactly how much bypass or recirculation is actually happening on a rack-by-rack basis.
“At the end of the day, the easiest way to reduce a data center’s electricity costs is to improve the cooling efficiency,” said Indra Purkayastha, CEO and Founder of Purkay Labs. “Our Delta-T Package tells you how much cold air is being wasted, right out of the box. There are no external programs or infrastructure integration required. The Delta-T Package allows data center managers to make data-driven decisions to adjust hot/cold aisle containment, cut down on CRAC use and reduce the overall kWh bill.”
The AUDIT-BUDDY Delta-T Package (PLP11) consists of 2 AUDIT-BUDDY Systems (6 TH1 Modules, 2 Carbon fiber rods), with each TH1 Module transferring data directly to a USB flash drive. The Delta-T Macro automatically combines the data from the six TH1 Modules, calculates the delta-T for a rack, the inlet/outlet temperatures over a given time period. With user input of HVAC settings, the Macro will report the degree of bypass or recirculation airflow present at that rack.
