Abstract
A method is provided for dissipating heat from a rack. The method includes: disposing a coolant-cooled heat exchanger within the rack, and providing a coolant control apparatus. The coolant control apparatus includes at least one coolant recirculation conduit coupled in fluid communication between a facility coolant supply and return, wherein the facility coolant supply and return facilitate providing facility coolant to the heat exchanger. The control apparatus further includes a coolant pump(s) associated with the recirculation conduit(s) and a controller which monitors a temperature of facility coolant supplied to the heat exchanger, and redirects facility coolant, via the coolant recirculation conduit(s) and coolant pump(s), from the facility coolant return to the facility coolant supply to, at least in part, ensure that facility coolant supplied to the heat exchanger remains above a dew point temperature.
