1. A system for detecting compressor degradation, comprising:

  • a compressor adapted to function at a plurality of operating parameters including an evaluated operating parameter;

    a processing and storage member for storing at least one dataset for said compressor relating said compressor operating parameters to each other;

    said processing and storage member being operatively associated with said compressor so as to detect real time actual values of said compressor operating parameters, and being adapted to;

    form a diagnostic subset of at least one of said real time actual values, wherein said diagnostic subset does not include said evaluated operating parameter;

    use said diagnostic subset and said dataset to determine a predicted value of said evaluated operating parameter; and

    compare said predicted value of said evaluated operating parameter to said real time actual value of said evaluated operating parameter.
