Title:
REFRIGERATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/098349
Kind Code:
A1
Abstract:
Oil separators (17a, 17b, 17c) are disposed on refrigerant discharge pipes (56a, 56b, 56c) of compressors (13a, 13b, 13c), and recover refrigerant oil that has become admixed into the discharged refrigerant from the compressors (13a, 13b, 13c). An oil return circuit (50) returns the refrigerant oil from the oil separators (17a, 17b, 17c) to the compressors (13a, 13b, 13c). An oil visual check instrument (100) having an observation window (103) that allows an inspector to visually check the flow of refrigerant oil is disposed on the oil return circuit (50). As a result, it is possible for an inspector to make an accurate visual check as to whether the amount of refrigerant oil for lubricating the compressors of a refrigerant device is insufficient.
