Calculation Formula

Energy Consumption (kWh) = (Flow Rate × Pressure Ratio ^ 0.28) / Efficiency

Where:
Flow Rate = Volume of gas compressed per hour
Pressure Ratio = Outlet Pressure / Inlet Pressure
Efficiency = Isentropic efficiency of the compressor (%)

Compressor Energy Calculator Usage Guide

Learn how to use the Compressor Energy Calculator and its working principles

How to Use the Calculator

  1. Enter the flow rate of the gas in cubic meters per hour (m³/h).
  2. Enter the inlet pressure of the gas in bar.
  3. Enter the outlet pressure of the gas in bar.
  4. Enter the isentropic efficiency of the compressor as a percentage (default is 75%).
  5. Click the "Calculate" button to compute the energy consumption.
  6. The results will show the pressure ratio and the energy consumption in kilowatt-hours (kWh).

Working Principle

The calculator uses the following formula to estimate energy consumption:

Energy Consumption (kWh) = (Flow Rate × Pressure Ratio ^ 0.28) / Efficiency

Where:

  • Flow Rate is the volume of gas compressed per hour.
  • Pressure Ratio is the ratio of outlet pressure to inlet pressure.
  • Efficiency is the isentropic efficiency of the compressor, representing how efficiently the compressor converts electrical energy to mechanical energy.

Applications

This calculator can be used by engineers, technicians, and facility managers to:

  • Estimate the energy requirements of compressors.
  • Compare the efficiency of different compressors.
  • Optimize compressor operations to reduce energy consumption.
  • Conduct energy audits for industrial facilities.
