<p><P>PROBLEM TO BE SOLVED: To prevent a cooling system of a computer room from breaking down owing to heat exchanger failure or control valve failure, or loss of chilled water source. <P>SOLUTION: A cooling system comprises at least two modular cooling units (MCU) and each MCU 310 provides system coolant to multiple electronics subsystems. The each MCU 310 comprises a heat exchanger 324, a first cooling loop 325 with at least one control valve 316, and a second cooling loop 327. The first cooling loop 325 receives chilled facility coolant from a source and passes at least a portion thereof through the heat exchanger. The second cooling loop supplies chilled system coolant to the multiple electronics subsystems and, in the heat exchanger 324, heat is expelled from the multiple electronics subsystems to the chilled facility coolant in the first cooling loop 325. At least one of control valve 316 controls flow and temperature of the facility coolant. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
