摘要： Disclosed is a refrigerant compressor system comprising at least three compressors which are arranged in parallel between a suction line and a pressure line and each of which includes a lubricant sump unit; during operation, the compressors operate in such a way that the pressures in the lubricant sump units of the compressors form a pressure cascade in which the compressors have a gradually slightly decreasing pressure in the associated lubricant sump units in a defined cascade sequence; the lubricant sump units are connected to each other according to the cascade sequence by means of a lubricant line system in order for lubricant to be delivered, and each lubricant sump unit includes a connection to which an insertion element is connected, the insertion element establishing a connection to the lubricant line system and being designed in such a way as to set, for the associated lubricant sump unit, a lubricant level from which lubricant is delivered to the subsequent lubricant sump unit in the cascade sequence.

摘要： An apparatus for detecting an oil level and a method for controlling the same, an apparatus for detecting oil flow and a method for controlling the same, and a method for controlling oil return using the detected oil level and the detected oil flow are disclosed. The level of oil stored in a compressor is measured at two or more positions. The frequency comparison scheme using two electrodes can correctly detect the level of oil stored in the compressor, a refrigerant state, and the level of mixed oils, and can determine an internal state of the compressor and a normal or abnormal state of the oil return system, such that the oil return control can be actively controlled. The flow of oil in the oil return pipe is detected so as to determine whether the oil is normally supplied in real time, such that a malfunction of the compressor is prevented and a valve state can be checked. The level of oil stored in the compressor is adjusted not only using the oil level detection result but also the oil flow detection result, and the oil return operation can be controlled.

摘要： A rotary compressor (100) includes a closed casing (1), a cylinder (15), a piston (28), a lower bearing member (7), a vane (33), a suction port, a discharge port (41), and a partition member (10). The partition member (10) is attached to a second principal surface (7a) of the lower bearing member (7) located on the opposite side to the cylinder (15) so as to form a refrigerant discharge space (52) serving as a flow path of a refrigerant discharged from a discharge chamber through the discharge port (41). The refrigerant discharge space (52) is limited so that a region where the refrigerant discharge space (52) is not present is formed on the same side as the suction port with respect to a first reference plane, and in that region, the second principal surface (7a) of the lower bearing member (7) is in contact with an oil in an oil reservoir (22) directly or via the partition member (10).
