DEVICE FOR DETECTING A NON-OPTIMAL LUBRICATION CONDITION IN A COMPRESSOR OF A REFRIGERATION SYSTEM, A COMPRESSOR UNIT WHICH COMPRISES THE DEVICE AND A METHOD FOR DETECTING A NON-OPTIMAL LUBRICATION CONDITION IN A COMPRESSOR OF A REFRIGERATION SYSTEM

摘要

1. A device (10) for detecting a non-optimal lubrication condition in a compressor (100) of a refrigeration system (1000), which comprises a transducer unit (11) designed to detect sound vibrations and emit an electrical signal as a function of the frequency of the sound vibrations.;The device (10) is configured to be fixed to an external wall of a compressor (100) in such a way that, in use, the transducer unit (11) detects sound vibrations which are emitted by the said compressor (100).;The transducer unit (11) is connectable to an electronic device for processing said electrical signal so as to signal if, in use, said frequency exceeds a predefined threshold that corresponds to a non-optimal lubrication condition of the compressor (100).
