Abstract
A refrigeration system includes a first cooling system having a refrigerant in thermal communication with a heat exchanger device to provide a first cooling source. A second cooling system has a coolant in thermal communication with the heat exchanger device and a refrigeration device is configured to receive the coolant. A third cooling system is configured to provide a second cooling source to the coolant when the first cooling source is unavailable, so that a pressure of the coolant does not exceed a predetermined level when the first cooling source is unavailable.
Claims58
A refrigeration system for providing cooling to a refrigeration device, comprising:
- a first cooling system having a refrigerant configured to communicate with a heat exchanger to provide a primary cooling source;
- a second cooling system having a coolant configured to be cooled by the primary cooling source and circulated to the refrigeration device;
- a separator device configured to receive the coolant from the refrigeration device and direct coolant in a vapor state to the heat exchanger and direct coolant in a liquid state to the refrigeration device.
A refrigeration system, comprising:
- a primary cooling system configured to circulate a refrigerant to a heat exchanger;
- a secondary cooling system configured to circulate a coolant to the heat exchanger and at least one refrigeration device;
- a separator configured to direct a vapor portion of the coolant to the heat exchanger and a liquid portion of the coolant to the refrigeration device;
- a third cooling system configured to cool a vapor portion of the coolant from the secondary cooling system.
A refrigeration system, comprising:
- a primary cooling system configured to provide a first source of cooling to a coolant;
- a secondary cooling system configured to circulate the coolant to at least one refrigeration device and to be cooled by the first source of cooling when the primary cooling system is operational;
- and
- at least one over-pressure protection device configured to maintain a pressure of the coolant below a predetermined pressure when the primary cooling system is not operational;
- so that the pressure of the coolant does not exceed a predetermined pressure.
