Document Type and Number:
Japanese Patent JP2017138034
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a refrigerating device capable of improving operation reliability.SOLUTION: A refrigerating device includes: a compressor in which a refrigerant is sucked from a low stage suction port through an inlet of the refrigerating device and which discharges the refrigerant from a high stage discharge port by performing a multi-stage compression; an oil separator for separating an oil from the discharge refrigerant from the high stage discharge port; an oil cooler for cooling the oil separated by the oil separator; an oil return circuit for returning the oil cooled by the oil cooler to the compressor; and a control part for increasing a circulation amount of the oil flowing in the oil return circuit, when it determines that the oil circulation amount in the oil return circuit is small, based on predetermined temperature information.SELECTED DRAWING: Figure 1
