REFRIGERATION DEVICE

Japanese Patent JP2016176664

A

PROBLEM TO BE SOLVED: To provide a refrigeration device which stores a proper amount of refrigeration machine oil in a compressor, and which can achieve improvement of performance by suppressing outflow into a refrigerant circuit.SOLUTION: A refrigeration device includes a compressor 11, an oil separator 21 connected to a discharge side of the compressor 11, and a first oil return pipeline 33 provided between the suction side of the compressor 11 and the oil separator 21 and for returning a refrigeration machine oil in the oil separator 21 to the compressor 11, and it performs a vapor compression type refrigeration cycle operation. The first oil return pipeline 33 includes an oil adjustment container 23 capable of storing oil, and a throttle member 24 for stabilizing an amount of the refrigeration machine oil in the compressor 11 at a predetermined amount by limiting a flow rate of the refrigeration machine oil returning to the compressor 11 from the oil adjustment container 23 at a constant rate.SELECTED DRAWING: Figure 2
