Abstract

A centralized cooling system can selectively deliver individualized cooling to individual electrical load units. The system can provide direct cooling from a manifold of cooling outlets in a controlled manner based on the sensed electrical loads of particular load units. A branch monitoring system monitors the load on electrical feeds that are coupled to electrical load units. A controller is coupled to the branch monitoring system and provides output to control a cooling unit. At least one control valve is further coupled to the controller downstream of the cooling unit generally at each cooling outlet to control an amount of cooling fluid, such as air or liquid, directed to one or more of the units. If a load changes for a given unit, the controller can actuate a cooling valve coupled to a corresponding cooling outlet and alter the amount of cooling fluid flowing into or around the unit(s).
