ISO 1217 Rotary Screw Compressor Efficiency Auditor

Professional Energy Audit Tool for Industrial Compressed Air Systems.

TECHNICAL PARAMETER DEFINITIONS

  • FAD (Free Air Delivery): The actual volume flow rate of air compressed and delivered, referred to the conditions of total temperature and pressure at the inlet.
  • Isentropic Efficiency: The definitive performance metric per ISO 1217, representing the ratio of theoretical minimum energy to actual electrical consumption.
  • Specific Power (kW/m3/min): A real-world efficiency benchmark showing the energy cost required to produce one unit of compressed air.
  • Absolute Pressure Ratio: A calculation using an absolute scale (Gauge Pressure + 1.013 bar) to ensure precise thermodynamic modelling.

PROFESSIONAL DISCLAIMER & COMPLIANCE

  • Compliance Standard: Strictly follows the thermodynamic equations defined in ISO 1217:2009 (Annexe C and E) for electrically driven packaged displacement compressors.
  • Carbon Intensity: Environmental impact is calculated using the Indian Grid Emission Factor (0.82kg co2/kwh)
  • Legal Disclaimer: This tool is for informational and preliminary auditing purposes. Results depend on the accuracy of user inputs. A physical on-site audit by a certified professional is recommended for critical investment decisions.
