Cooling systems and methods of cooling

A cooling system for cooling at least one heat source, comprising:

• a cooling tower;
• a first valve in fluid connection with the heat source, the cooling tower, and a discharge vessel, the first valve being switchable between at least a first position that provides a fluid connection between the heat source and the cooling tower and a second position that provides a fluid connection between the heat source and the discharge vessel;
• at least one second valve, each of the at least one second valve in fluid communication with a cooling fluid source, the cooling tower and a respective one of the at least one heat source, the at least one second valve being switchable between a first position that provides a fluid connection between the cooling tower and the respective one of the at least one heat source and a second position that provides a fluid connection between the cooling fluid source and the respective one of the at least one heat source;
• a first pump in fluid connection with the cooling tower and the at least one heat source, the first pump selectively operating to pump cooling fluid between the at least one heat source and the cooling tower when the first valve is in the first position;
• and
• at least one intake pump in fluid communication with the cooling fluid source and a respective one of the at least one second valve, the intake pump selectively operating to pump cooling fluid from the cooling fluid source to the respective one of the at least one heat source when the respective one of the at least one second valve is in the second position.

A cooling system for cooling a heat source, comprising:

• a cooling tower in fluid communication with the heat source;
• a discharge channel in fluid communication with the heat source;
• an inlet channel in fluid communication with the discharge channel and the cooling tower;
• an outlet channel in fluid communication with the discharge channel;
• a first gate selectively operable to open and close a first fluid passageway between the discharge channel and the inlet channel;
• second gate selectively operable to open and close a second fluid passageway between the discharge channel and the outlet channel;
• a first pump in fluid communication with the cooling tower and the inlet channel, the first pump selectively operating to pump cooling fluid from the inlet channel to the cooling tower, the first gate operating to open the first passageway to allow cooling fluid flow from the heat source, through the discharge channel and to the inlet channel;
• a first valve in fluid communication with the cooling tower, the heat source and a cooling fluid source, the first valve being switchable between at least a first position that provides a fluid connection between the cooling tower and the heat source and a second position that provides a fluid connection between the cooling fluid source and the heat source;
• and
• an intake pump in fluid communication with the cooling fluid source and the first valve, the intake pump selectively operating to pump cooling fluid from the cooling fluid source to the heat source when the second valve is in the second position.
