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 2):
A refrigeration apparatus comprising:\n a compressor that has a built-in motor having rotation thereof controlled by inverter control, the compressor being configured to compress refrigerant that flows through a refrigerant circuit; an inverter controller that controls torque of the motor through the inverter control when operation frequency of the compressor is at least one value within a range of from 10 Hz to 40 Hz; and a device controller that, when at least the operation frequency is within the range of from 10 Hz to 40 Hz, torque of the motor is controlled, and it is determined that a predetermined condition is satisfied, controls devices provided in the refrigerant circuit such that intermediate-pressure refrigerant within the refrigerant circuit is injected into refrigerant undergoing compression in the compressor, wherein the predetermined condition is one condition selected from among: a condensation temperature condition in which a condensation temperature of the refrigerant circuit is 45\u00b0 C. or higher, a high-pressure condition in which pressure on a high-pressure side of the refrigerant circuit is a predetermined pressure or more, a pressure difference condition in which a difference in pressure between the high-pressure side and a low-pressure side of the refrigerant circuit is a predetermined difference or more, and an outside temperature condition in which temperature of outside air that is heat exchanged with refrigerant that flows through the refrigerant circuit is a predetermined temperature or more.
