Abstract
A vapor-compression system includes a centrifugal compressor configured to increase a pressure of a refrigerant based on at least one of an activation of a device or the device being equal to or above a first threshold temperature. A fluid communication system is configured to provide, to the device, a portion of the refrigerant in a liquid state. The portion of the liquid refrigerant in a liquid state is configured to have a saturation temperature equal to or below the first temperature threshold.
Claims20
A vapor-compression system comprising:
- a centrifugal compressor configured to increase a pressure of a refrigerant based on at least one of an activation of a device or a temperature of the device being equal to or above a first threshold temperature;
- and
- a fluid communication system configured to provide, to the device, a portion of the refrigerant in a liquid state, wherein the portion of the refrigerant in the liquid state is configured to have a saturation temperature equal to or below the first temperature threshold.
A method of cooling a device, the method comprising:
- increasing, via a centrifugal compressor, a pressure of a refrigerant upon at least one of an activation of a device or a temperature of the device being equal to or above a first threshold temperature;
- and
- providing, via a fluid communication system, a portion of the refrigerant in a liquid state to the device, wherein the portion of the refrigerant in the liquid state has a saturation temperature equal to or below the first temperature threshold.
A vapor-compression system comprising:
- a centrifugal compressor configured to increase a pressure of a refrigerant based on at least one of an activation of a device or a temperature of the device being equal to or above a first threshold temperature;
- a condenser in fluid communication with the centrifugal compressor and configured to remove heat and condense at least a portion of the refrigerant to a liquid state;
- an expansion valve in fluid communication with the condenser and configured to decrease a pressure of the refrigerant;
- and
- a fluid communication system configured to provide, to the device, the portion of the refrigerant in the liquid state, wherein the portion of the liquid refrigerant in the liquid state is configured to have a first saturation temperature equal to or below the first temperature threshold, wherein the fluid communication system is further configured to provide a second portion of the refrigerant in a liquid state to a thermal capacitor downstream from the device, wherein the second portion of the refrigerant in the liquid state has a second saturation temperature equal to or below the first saturation temperature,
- wherein the centrifugal compressor is further configured to shut off based on at least one of the device being deactivated or the temperature of the device being equal to or below a second threshold temperature.
