Title:
COOLING WATER SUPPLY SYSTEM AND METHOD
Document Type and Number:
WIPO Patent Application WO/2016/087920
Kind Code:
A3
Abstract:
The present invention provides a cooling water supply system, comprising a condenser for cooling working fluid of a facility to a predetermined temperature; a cooling tower into which is injectable heated cooling water that has exited said condenser, for reducing the temperature of said heated cooling water primarily through evaporative cooling; a basin beneath said cooling tower, for receiving a non-evaporated portion of said heated cooling water discharged from the cooling tower; and flow control equipment for varying the level of a fluid characteristic of a water body of said cooling water within the basin, wherein the body of water, after achieving a predetermined low level of water fluid characteristic by said flow control equipment, remains at a sufficiently low temperature throughout a subsequent predetermined time period to generate a desired condensate temperature by a portion thereof that is delivered to said condenser, even when mixed with the cooling tower discharge which is of a higher temperature than the temperature of the body of water.
