Compressor/Fan Efficiency Data

Note: All efficiency data in the Compressor junction is treated as an isentropic efficiency.

Best Efficiency Point (BEP)

By defining a power or efficiency curve, the Best Efficiency Point of the compressor/fan can be found. Optionally, the calculated value can be overridden with a user-defined value on the Configuration Data tab on the Compressor/Fan Configuration window. It is generally desirable to operate compressors/fans as close to the BEP as possible. The Compressor/Fan Summary tab in the Output can display what the BEP is, as well as how far off (in % of BEP) of BEP the compressor/fan is operating in the model.

Nominal Efficiency

When modeling a fixed flow or fixed rise compressor/fan, you can optionally input a nominal efficiency as an approximation. This can be useful for sizing or design purposes, although more precise efficiency data should be entered when modeling a compressor/fan curve.
