REFRIGERATION DEVICE
Document Type and Number:
Japanese Patent JP2016161211
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a refrigeration device capable of suppressing damage of a slide part caused by a low viscosity refrigerating machine oil which is diluted by a refrigerant being supplied to the slide part of a compressor.SOLUTION: A refrigeration device incudes: a scroll compressor 111; an oil separator 112; a first throttle part 113; a heat exchanger 114; and an oil supply part. The scroll compressor 111 has: a compression chamber in which a refrigerant is compressed; and a slide part to which a refrigerating machine oil is supplied. In the oil separator 112, the refrigerating machine oil supplied to the slide part is stored. The first throttle part 113 decompresses the refrigerating machine oil stored in the oil separator 112. The heat exchanger 114 heats the refrigerating machine oil decompressed in the first throttle part 113 by the heat of the refrigerant compressed in the compression chamber. The oil supply part supplies the refrigerating machine oil which is heated in the heat exchanger 114 and in which at least one part of the refrigerant mixed in the refrigerating machine oil is evaporated and removed to the scroll compressor 111.SELECTED DRAWING: Figure 2
