  • METHOD AND APPARATUS FOR OIL SENSING IN A COMPRESSOR
    Publication number: 20160230762
    Abstract: A method comprising determining a first temperature of an oil inside a compressor; determining a second temperature at a moveable part of the compressor, wherein the second temperature at the moveable part is determined at a stationary part of the compressor being in contact with the moveable part; and deriving whether the compressor operates in a safe mode or in an unsafe mode based on an analysis of the determined first temperature and the determined second temperature at the moveable part.

  • Plural compressors
    Patent number: 7201567
    Abstract: A compressor system includes a pair of compressors located in a common shell. A common drive shaft drives both compressors and the drive shaft is powered by a single motor. One or both of the compressors can be equipped with a pulse width modulated capacity control system and a vapor injection system. When one compressor is equipped with these systems, the capacity can be varied between 50% and 110%. When both compressors are equipped with these systems, the capacity can be varied between 0% and 120%.
