... the change of the control type will affect the supply fluid temperature and the TTV case temperatures at 10%, 50%, and 100% of the total power. Finally, suggestions for the best control fan scheme to use for these systems and units are provided at the conclusion of the study. data center high heat...

...R. Khalid; S. G. Schon; R. L. Amalfi; A. Ortega; A. P. Wemhoff This study aims to improve the combined energy efficiency of data center cooling systems and heating/cooling systems in surrounding premises by implementing a modular cooling approach on a 42 U IT rack. The cooling solution uses a close...

.... Cooling and other secondary equipment in a data center (DC) consume an average of about 43% of total DC power [ 1 ]. These equipment, combined with information technology (IT) equipment, generate a significant amount of low-grade waste heat with little economic value. Moreover, no major improvement in DC...

...Aaron P. Wemhoff; Faisal Ahmed Physics-based modeling aids in designing efficient data center power and cooling systems. These systems have traditionally been modeled independently under the assumption that the inherent coupling of effects between the systems has negligible impact. This study tests...

...Sebastian Araya; Aaron P. Wemhoff; Gerard F. Jones; Amy S. Fleischer The ongoing growth in data center rack power density leads to an increased capability for waste heat recovery. Recent studies revealed the organic Rankine cycle (ORC) as a viable means for data center waste heat recovery since...

...Yogesh Fulpagare; Atul Bhargav; Yogendra Joshi With the explosion in digital traffic, the number of data centers as well as demands on each data center, continue to increase. Concomitantly, the cost (and environmental impact) of energy expended in the thermal management of these data centers...

...Rehan Khalid; Aaron P. Wemhoff Two self-developed control schemes, ON/OFF and supervisory control and data acquisition (SCADA), were applied on a hybrid evaporative and direct expansion (DX)-based model data center cooling system to assess the impact of controls on reliability and energy efficiency...

... on the thermal performance. To express the flow and heat transfer process of cold air in servers and analyze the critical factors affecting the temperature rise, a simplified mathematical model representing servers is developed using experimental results. An experiment is conducted within a modular data center...

... of CAC in data centers. The models are based on measured fan curves for the CRAC unit as well as the load banks, which are used to simulate servers. The models are verified by measuring flow rates and temperatures at critical points in the data center. The modeling process also includes a careful...
