Real-time cooling control of data centers is a challenging task. On one hand, thermal requirements of the IT equipment with time-varying and spatially non-uniform loads need to be satisfied at any given time. On the other hand, various cooling actuations within the data center, such as supply air temperature and blower speed of the computer room air conditioning units, need to be coordinated to lower the cooling cost. In this talk, dynamic model describing the air flow transport and distribution within the data center is derived from the mass and energy balance principles. The holistic dynamic model captures the causal relationship between various cooling actuations and the resulting rack inlet temperature change, and can be used in such tasks as data center thermal zone mapping, optimization of air flow distribution, and real-time cooling control. The cooling control approach proposed has been implemented in a research data of HP Labs in Palo Alto, and benefits including energy savings, thermal disturbance rejection, and robustness with respect to failures of cooling units have been observed.  


Rongliang Zhou is currently a research scientist in Sustainable Ecosystem Research Group (SERg) at HP Labs, Palo Alto. His main research interest is modeling and control of thermal systems and energy efficient systems. He received his doctoral degree in electrical engineering from Rensselaer Polytechnic Institute in 2010. Prior to that, he received a master degree in electrical engineering in 2003, and a dual bachelor degree in electrical engineering and computer science in 2000, both from Xi'an Jiaotong University, China.
