Abstract
Operating refrigeration systems is described herein. One method includes receiving operating information associated with a refrigeration system, and determining a probability of liquid slugging occurring in the refrigeration system before liquid slugging occurs in the refrigeration system based, at least in part, on the operating information.
Claims18
A method of operating a refrigeration system, comprising:
- receiving operating information associated with a refrigeration system, wherein at least a portion of the operating information is received from a sensor associated with an inlet of a compressor rack of the refrigeration system;
- determining a respective probability of liquid slugging caused by each of a plurality of components of the refrigeration system before liquid slugging occurs in the refrigeration system based, at least in part, on the operating information;
- and
- providing a notification responsive to at least one determined probability of the plurality of probabilities meeting or exceeding a particular threshold probability, wherein the notification includes a display of a hierarchy of the plurality of components according to the respective probability of liquid slugging caused by each of the plurality of components.

A system for operating a refrigeration system, comprising:
- a first sensor associated with an inlet of a compressor rack of a refrigeration system;
- a second sensor associated with an evaporator of the refrigeration system;
- and
- a computing device configured to:
- receive operating information associated with the compressor rack and/or evaporator from the first and/or second sensors while the refrigeration system is operating;
- determine a number of faults based, at least in part, on the operating information;
- detect liquid slugging associated with the refrigeration system based, at least in part, on the determined number of faults and/or the operating information;
- determine a respective probability of liquid slugging caused by each of a plurality of components of the refrigeration system based, at least in part, on the determined number of faults and/or the operating information;
- and
- provide a notification responsive to at least one determined probability of the plurality of probabilities meeting or exceeding a particular threshold probability, wherein the notification includes a display of a hierarchy of the plurality of components according to the respective probability of liquid slugging caused by each of the plurality of components.
7 more elements
A computing device for operating a refrigeration system, comprising:
- a memory;
- and
- a processor coupled to the memory;
- wherein the processor is configured to execute executable instructions stored in the memory to:
- receive evaporator data and compressor rack data associated with a refrigeration system, wherein the compressor rack data includes data determined by a sensor associated with an inlet of a compressor rack;
- determine a number of aggregated faults based, at least in part, on the evaporator data and the compressor rack data;
- determine a respective probability of liquid slugging caused by each of a plurality of components of the refrigeration system based, at least in part, on the aggregated faults;
- and
- provide a notification responsive to at least one determined probability of the plurality of probabilities meeting or exceeding a particular threshold probability, wherein the notification includes a display of a hierarchy of the plurality of components according to the respective probability of liquid slugging caused by each of the plurality of components.
