摘要： A compressor surge detection system (1) for a refrigerating apparatus (100), comprises: a sensing system, configured for detecting a monitoring parameter representative of a saturating evaporating temperature of the refrigerating fluid at an inlet (I) of the compressor; a processing unit, programmed to process the monitoring parameter for deriving a diagnostic parameter, representative of an oscillatory behavior for the monitoring parameter and for generating an alert signal in response to the diagnostic parameter.

摘要： A compressor surge detection system (1) for a refrigerating apparatus (100), comprises: a sensing system, configured for detecting a monitoring parameter representative of either (i) an electrical current absorbed by an electrical motor of a compressor (102) of the refrigerating apparatus or (ii) a saturating evaporating temperature of the refrigerating fluid at an inlet (I) of the compressor; a processing unit, programmed to process the monitoring parameter for deriving a diagnostic parameter, representative of an oscillatory behavior for the monitoring parameter and for generating an alert signal in response to the diagnostic parameter.
