To provide a refrigerating device capable of eliminating the defective compression state of a compressor in an early period, and stably being operated with high efficiency.
The refrigerating device has a two-stage type compressor 11 having a low-stage compressing element 11A and a high-stage compressing element 11B, so that a refrigerant of intermediate pressure compressed by the low-stage compressing element 11A is guided to the high-stage compressing element 11B to be compressed, and a high-pressure refrigerant is discharged to a gas cooler 23, and furthermore, has a defective compression eliminating means for discriminating a refrigerant compression state in the compressor on the basis of the refrigerant pressure of intermediate pressure and high pressure, and eliminating the defective compression state by controlling high pressure to be higher than intermediate pressure in the case that the compression state of the refrigerant reaches the defective compression state that intermediate pressure is higher than high pressure, or in the case that it is estimated that the compression state of the refrigerant becomes the defective compression state.
