Abstract
Methods and apparatus are provided for choosing an energy-efficient coolant temperature for electronics by considering the temperature dependence of the electronics' power dissipation. This dependence is explicitly considered in selecting the coolant temperature Tthat is sent to the equipment. To minimize power consumption Pfor the entire system, where P=P+Pis the sum of the electronic equipment's power consumption Pplus the cooling equipment's power consumption P, Pis obtained experimentally, by measuring Pand P, as a function of three parameters: coolant temperature T; weather-related temperature Tthat affects the performance of free-cooling equipment; and computational state C of the electronic equipment, which affects the temperature dependence of its power consumption. This experiment provides, for each possible combination of Tand C, the value T* of Tthat minimizes P. During operation, for any combination of Tand C that occurs, the corresponding optimal coolant temperature T* is selected, and the cooling equipment is commanded to produce it.
