A freezing device including a compressor that is configured to compress sucked refrigerant using a compression mechanism and to discharge compressed refrigerant, the freezing device comprising: a compressor including a motor that is configured to drive the compression mechanism, a low pressure unit in which the sucked refrigerant flows, a compression space in which the refrigerant flowing in the low pressure unit is compressed, a high pressure unit in which the refrigerant compressed in the compression space flows, a communication flow path through which the low pressure unit and the high pressure unit communicate, and a flow control valve that is provided in the communication flow path and that is configured to control a flow rate of the refrigerant flowing through the communication flow path; an inverter that is configured to supply a voltage to the compressor and to drive or stop the motor; and a controller configured to control the inverter and the flow control valve, wherein the controller is configured to perform, in stop control in which an operation of the compressor is stopped, and pressure equalization control in which pressure in the high pressure unit is equalized with pressure in the low pressure unit by opening the flow control valve; characterised in that the controller is configured to perform in said stop control a braking control in which driving of the compression mechanism is prevented or suppressed by controlling the inverter. a compressor including a motor that is configured to drive the compression mechanism, a low pressure unit in which the sucked refrigerant flows, a compression space in which the refrigerant flowing in the low pressure unit is compressed, a high pressure unit in which the refrigerant compressed in the compression space flows, a communication flow path through which the low pressure unit and the high pressure unit communicate, and a flow control valve that is provided in the communication flow path and that is configured to control a flow rate of the refrigerant flowing through the communication flow path; a motor that is configured to drive the compression mechanism, a low pressure unit in which the sucked refrigerant flows, a compression space in which the refrigerant flowing in the low pressure unit is compressed, a high pressure unit in which the refrigerant compressed in the compression space flows, a communication flow path through which the low pressure unit and the high pressure unit communicate, and a flow control valve that is provided in the communication flow path and that is configured to control a flow rate of the refrigerant flowing through the communication flow path; an inverter that is configured to supply a voltage to the compressor and to drive or stop the motor; and a controller configured to control the inverter and the flow control valve, wherein the controller is configured to perform, in stop control in which an operation of the compressor is stopped, and pressure equalization control in which pressure in the high pressure unit is equalized with pressure in the low pressure unit by opening the flow control valve; characterised in that the controller is configured to perform in said stop control a braking control in which driving of the compression mechanism is prevented or suppressed by controlling the inverter.
