Abstract:
To reduce the possibility that temperature of refrigerant discharged from a compressor of a refrigeration apparatus becomes excessively high by controlling torque of a motor built into the compressor, the compressor includes the motor having rotation thereof controlled by inverter control. An inverter controller controls torque of the motor using inverter control when operation frequency of the compressor is at least one value within a range of from 10 Hz to 40 Hz. When at least the operation frequency is within the range of from 10 Hz to 40 Hz, torque of the motor is controlled, and under a predetermined condition in which temperature of refrigerant discharged from the compressor easily becomes excessively high, a device controller controls devices provided in a refrigerant circuit such that refrigerant sucked into the compressor is placed in a wet vapor state.

Claim (Index 3):
The refrigeration apparatus according to  claim 1 , further comprising:\n a pressure reducing mechanism provided in the refrigerant circuit as one of the devices for reducing pressure of the refrigerant that flows through the refrigerant circuit; and an outdoor fan that is provided in the refrigerant circuit as one of the devices for supplying the outside air to be heat exchanged with the refrigerant flowing through the refrigerant circuit, the outdoor fan being configured to be able to change an amount of air sent, wherein, when at least the operation frequency is within the range of from 10 Hz to 40 Hz, torque of the motor is controlled, and under the predetermined condition, the device controller changes a degree of pressure reduction by the pressure reducing mechanism or controls the amount of air sent by the outdoor fan, to thereby place the refrigerant sucked into the compressor in a wet vapor state.
