Abstract (en)
[origin: EP3483529A1] A monitoring system of lubricant of a compressor (3) of a refrigerant circuit (2) for a compressible fluid where the compressor is equipped with an intake (5) and a delivery (9), comprises an on-off state detector (11) of compressor (3) and a pressure sensor (13) connected to a monitoring device (15) to provide data to the latter respectively on operating or switch-off status of compressor (3) and on the pressure of compressible fluid at compressor delivery (9). When the monitoring device (15) detects that the compressor status switches from on to off, said monitoring device (15) compares the progression of compressible fluid pressure at delivery (9), starting from the switching instant in the shutdown state, with a predetermined progress memorized therein. In case of a discrepancy between the two progressions exceeding a predetermined threshold, the monitoring device (15) emits at least one alarm signal.
