Abstract
Systems and methods for compressor unloading detection are provided and include a compressor having a compression mechanism. A controller determines a predicted discharge temperature of the compressor, receives an actual discharge temperature of the compressor, and compares the predicted discharge temperature with the actual discharge temperature. The controller also compares a speed of the compressor with a speed threshold and detects unloading of the compression mechanism based on the comparison of the predicted discharge temperature with the actual discharge temperature and based on the comparison of the speed of the compressor with the speed threshold. The controller performs at least one of generating an alert and a remediating action in response to detecting the unloading of the compression mechanism.

A system comprising:
- a compressor having a compression mechanism;
- and
- a controller that determines a predicted discharge temperature of the compressor, that receives an actual discharge temperature of the compressor, that compares the predicted discharge temperature with the actual discharge temperature, that compares a speed of the compressor with a speed threshold, that detects unloading of the compression mechanism based on the comparison of the predicted discharge temperature with the actual discharge temperature and based on the comparison of the speed of the compressor with the speed threshold, and that performs at least one of generating an alert and a remediating action in response to detecting the unloading of the compression mechanism.
A method comprising:
- determining, with a controller, a predicted discharge temperature of a compressor having a compression mechanism;
- receiving, with a controller, an actual discharge temperature of the compressor;
- comparing, with the controller, the predicted discharge temperature with the actual discharge temperature;
- comparing, with the controller, a speed of the compressor with a speed threshold;
- detecting, with the controller, unloading of the compression mechanism based on the comparison of the predicted discharge temperature with the actual discharge temperature and based on the comparison of the speed of the compressor with the speed threshold;
- and
- performing, with the controller, at least one of generating an alert and a remediating action in response to detecting the unloading of the compression mechanism.
