Abstract
Provided is a refrigeration apparatus including a refrigeration circuit, a liquid bypass circuit and a controller that opens a liquid bypass control valve when a discharge temperature of the refrigerant, which has been discharged from a compressor and does not yet flow into a condenser exceeds a threshold value, and closes the liquid bypass control valve when the discharge temperature is equal to or less than the threshold value. The refrigeration apparatus also regulates revolutions of the compressor such that an evaporation pressure of the refrigerant, which flows through a refrigeration circuit at a position downstream of an evaporator and upstream of the compressor, the position being downstream of a downstream-end connection point of a liquid bypass flow path, corresponds to a preset target evaporation pressure.
