摘要： In order to improve a method for selecting a frequency converter for a refrigerant compressor unit comprising a refrigerant compressor and an electric drive motor in such a way that the frequency converter is optimised for the application in question, it is proposed that a working state suitable for the operation of the refrigerant compressor unit is selected in an application field of an application diagram of the refrigerant compressor, that an operating frequency is selected for this selected working state, and that, on the basis of drive data, a working state operating current value corresponding to the selected working state and the selected operating frequency is ascertained for the operation of the refrigerant compressor unit

摘要： In order to improve a screw compressor comprising a housing, at least one screw rotor arranged in a compressor housing of the housing, a lubricant sump which is arranged on the high pressure side and in which lubricant collects, and a lubricant supply device which supplies lubricant from the lubricant sump to the at least one screw rotor, in such a manner that the amount of circulating lubricant can be kept as small as possible for adequate lubrication, it is suggested that the lubricant supply device comprise a first lubricant supply system and a second lubricant supply system, that the first lubricant supply system supply lubricant to the at least one screw rotor during operation of the screw compressor and that the second lubricant supply system additionally supply lubricant to the at least one screw rotor and thereby be activatable and deactivatable.
