<p>PURPOSE:To stop a faulty refrigerating machine in an early period and switch it over to a stand-by refrigerating machine, by a method wherein the leakage of flon refrigerant is detected by detecting the leakage of lubricating oil for a compressor, which leaks together with the flon refrigerant simultaneously. CONSTITUTION:A leak sensor 9 for detecting the leakage of lubricating oil for a compressor is prepared below a part such as a flon refrigerant pipeline 5, the joint of the flon refrigerant pipeline 5 and the like where the operational vibration of the compressor 10 is delivered and the leakage of the flon refrigerant is readily caused. The lubricating oil for the compressor 10 is contained in a flon refrigerating cycle except the flon refrigerant. When the leakage of the flon refrigerant is caused, the leakage of the lubricating oil is caused simultaneously, therefore, the leakage of the oil is detected immediately by the leak sensor 9 and the detected leakage is informed to a control unit 23 through signal wires 4.</p> |
