Abstract:
1. A cooling system comprising: multiple coolant conditioning units (CCUs), each CCU of at least some coolant conditioning units of the multiple CCUs providing system coolant to a different, associated electronics subsystem of multiple electronics subsystems to be cooled; and wherein each CCU of the at least some CCUs comprises a heat exchanger, a first cooling loop with a control valve, and a second cooling loop, the first cooling loop receiving chilled facility coolant from a source and passing at least a portion thereof via the control valve through the heat exchanger, the second cooling loop providing cooled system coolant to the associated electronics subsystem, and expelling heat in the heat exchanger from the associated electronics subsystem to the chilled facility coolant in the first cooling loop, wherein the control valve allows regulation of facility coolant flow through the heat exchanger, thereby allowing independent control of a desired temperature of the system coolant in the second cooling loop for cooling the associated electronics subsystem.
