Abstract:
A system for detecting antifreezing substances in a hermetic compressor, which has been removed from a refrigeration circuit, said compressor comprising a hermetic shell having at least one nozzle, which communicates the inside of said shell with the environment, said system comprising an antifreezing substance detecting means, containing at least one reactant, which is contactable with the atmosphere inside the shell through the nozzle, said antifreezing substance detecting means showing an alteration which is detectable when contacted by a determined amount of said antifreezing substance during a determined time interval, within which the determined amount of the antifreezing substance existing in the hermetic shell is able to cause the detectable alteration of the antifreezing substance detecting means, wherein the system further comprises a gas impelling means, which is operatively connected to the inside of said shell so as to cause the displacement of an air mass therewithin.
