Abstract: Provided is a refrigeration apparatus capable of appropriately supplying oil separated by oil separators to compressors according to the situation. The refrigeration apparatus includes N refrigeration units each including a compressor, an oil separator, an oil return pipe, and a heat dissipation heat exchanger; N pressure reducing valves each connected to the heat dissipation heat exchanger of a corresponding one of the N refrigeration units; and an oil return control mechanism that controls a return destination of the oil separated by the oil separators of the N refrigeration units. The oil return control mechanism includes an oil supply pipe that connects the oil return pipes of the N refrigeration units to each other, and a flow control mechanism, which controls a flowing condition of oil in the oil supply pipe, disposed in the oil supply pipe.
