<P>PROBLEM TO BE SOLVED: To provide a compression type refrigerating machine capable of eliminating bias of a refrigerant among refrigerating cycles, and continuing a stable operation, in the compression type refrigerating machine having the plurality of refrigerating cycles. Ž<P>SOLUTION: This compression type refrigerating machine comprises two sets of refrigerating cycles 100A, 100B in which the refrigerant are enclosed. Each of the refrigerating cycles 100A, 100B has an evaporator 10, 13, a compressor 15, 17, and a condenser 19, 21, and both compressors 15, 17 are driven by one motor 29. Liquid level sensors 43, 45 for detecting refrigerant retaining liquid levels of the evaporators 10, 13 of both refrigerating cycles 100A, 100B are disposed, and a refrigerant control mechanism is disposed to move the refrigerant from the refrigerating cycle 100A free from shortage of refrigerant, to the refrigerating cycle 100B specified by detection output from the liquid level sensor 43, 45 and having shortage of refrigerant. The refrigerant control mechanism comprises the liquid level sensors 43, 45, piping 51, a control valve 53, and a control means 55. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
