摘要： A refrigerant recovery system (90A) is equipped with an extraction pipe (61), a stabilizer holding container (70), a recovery pipe (62), a recovery container (80), and a recovery device (85). The extraction pipe (61) is connectable to a refrigerant extraction port (18) of an air conditioning apparatus (100). The stabilizer holding container (70) is connected to the extraction pipe (61) and holds a stabilizer (A). The stabilizer holding container (70) causes refrigerant guided by the extraction pipe (61) to come into contact with the stabilizer (A). The recovery pipe (62) guides the refrigerant discharged from the stabilizer holding container (70). The recovery container (80) is connected to the recovery pipe (62) and recovers the refrigerant guided by the recovery pipe (62). The recovery device (85) causes the refrigerant to move from the refrigerant extraction port (18) to the recovery container (80). The refrigerant includes a compound represented by a molecular formula having one or more carbon-carbon unsaturated bonds.

摘要： Provided is a compressor in which degradation of an insulating member due to hydrolysis is sufficiently suppressed and degradation of reliability is suppressed. A compressor (11) includes a casing (50), a compression mechanism (20), and an insulating film (86c). The casing (50) stores a refrigerating machine oil. The compression mechanism (20) is housed within the casing (50) and compresses a refrigerant. The insulating film (86c) is housed within the casing (50) and is formed of a polymer having an ester bond. The refrigerant includes a hydrocarbon as a main component. The refrigerant has a saturated water content of less than 0.3% by weight. The refrigerating machine oil has a saturated water content of 1.8% by weight or more.

摘要： A refrigeration apparatus (10) includes a bearing monitor (23). If an abnormal state condition is satisfied, the bearing monitor (23) performs an abnormal-state operation for coping with poor lubrication on a plain bearing of a compressor (50). The abnormal state condition is a condition indicating that a rate of change of current exceeds a first reference value. The rate of change of current is an amount of change in a driving current for driving the compressor (50) (i.e., a value measured by a current sensor) per unit time. A drive shaft of the compressor (50) has a journal portion supported by the plain bearing and having a surface roughness Ra greater than or equal to 0.05 µm.

摘要： The present invention provides a heat transport device in which a hydrohaloolefin-containing refrigerant is enclosed in a circulation route, and the heat transport device is capable of reducing the influence of oxygen entrapped in the circulation route. The present invention also provides a heat transport method using the heat transport device. In the heat transport device 1, a refrigerant comprising at least one of hydrofluoroolefins (HFOs), hydrochlorofluoroolefins (HCFOs), or hydrochloroolefins (HCOs) is enclosed in a circulation route, and a stabilizer container comprising an acid scavenger and/or an antioxidant is disposed in the circulation route. The antioxidant is at least one member selected from the group consisting of alkylcatechols, alkoxyphenols, benzoquinones, phenothiazines, and phthalates, and the acid scavenger is at least one member selected from the group consisting of aliphatic alcohols, polyhydric alcohols, amines, terpenes, alkyl epoxides, and alkenyl tolyls.
