Abstract
A cooling system including a primary cooling module supplying refrigerant to a circuit including a thermal load. A secondary cooling module provides a supplemental flow of refrigerant to the circuit upon detection of a deficiency of the primary cooling module. A valve is disposed between the primary: module and the circuit to prevent refrigerant flow between the primary cooling module in the circuit. The secondary cooling module transactions from a standby mode of operation to an online mode of operation and the primary cooling module is deactivated in response to detection of the deficiency of the primary cooling module.
Claims13
A cooling system comprising:
- a primary cooling module, the primary cooling module supplying refrigerant to a circuit including a thermal load;
- a secondary cooling module, the secondary cooling module providing a supplemental flow of refrigerant to the circuit upon detection of a deficiency of the primary cooling module;
- and
- at least one valve disposed between the primary cooling module and the circuit to prevent refrigerant flow therebetween,
- wherein the secondary cooling module is configured to transition from a standby mode of operation to an online mode of operation and the primary cooling module is deactivated in response to detection of the deficiency of the primary cooling module.
A cooling system comprising:
- a plurality of primary cooling modules, the primary cooling modules circulating refrigerant through a respective one of a plurality of thermal loads;
- a secondary cooling module, the secondary cooling module selectively providing a supplemental flow of refrigerant through a load associated with a primary cooling module for which a fault has been detected;
- and
- at least one valve disposed between each of the plurality of primary cooling modules and the load to prevent refrigerant flow therebetween,
- wherein the secondary cooling module is configured to transition from a standby mode of operation to an online mode of operation and the primary cooling module for which a fault has been detected is deactivated in response to detection of the fault of the primary cooling module for which a fault has been detected.
A method for providing redundant cooling in a cooling system comprising:
- providing a primary cooling module having a circuit, the primary cooling module providing cooling fluid to a thermal load;
- providing a secondary cooling module;
- arranging at least one valve between the primary cooling module and the load to prevent refrigerant flow therebetween;
- initiating operation of the secondary cooling module upon detection of a fault in the primary cooling module;
- inserting the secondary cooling module into the circuit, the secondary cooling module providing cooling fluid to the thermal load;
- deactivating the primary cooling module;
- and
- transitioning the secondary cooling module from a standby mode of operation to an online mode of operation and the primary cooling module is deactivated in response to detection of the fault of the primary cooling module.
