REFRIGERATION DEVICE

A refrigeration device (10) is fitted with a bearing monitoring unit (23). The bearing monitoring unit (23) is configured to perform, if an anomaly condition is satisfied, an anomalous-event operationcorresponding to a lubrication defect in a sliding bearing of a compressor (50). The anomaly condition is a condition indicating that a current change rate, which is the amount of change per unit time of a drive current (i.e., a measured value from a current sensor ()) for driving the compressor (50), has exceeded a first reference value. With respect to a drive shaft of the compressor (50), a journal portion supported on the sliding bearing has a surface roughness Ra of not less than 0.05 [mu]m. 在制冷装置(10)设置有轴承监视部(23)。轴承监视部(23)构成为，当异常条件成立时，实施与压缩机(50)的滑动轴承的润滑不良相对应的异常时动作。异常条件是表示电流变化率超过了第一基准值的条件，所述电流变化率是用于驱动压缩机(50)的驱动电流(即电流检测器的计测值)的每单位时间的变化量。另外，压缩机(50)的驱动轴的支承于滑动轴承的轴颈部的表面粗糙度Ra为0.05μm以上。
