Energy Efficiency guide for Air Compressors

This Course is specially design for Mechanical Engineering students, Utility Managers/Maintenance Mangers.

• significant amount of electricity used by Air compressors in the industries.

• It is used in a variety of industries to supply process requirements, to operate pneumatic tools and equipment

• Only 10 – 30% of energy reaches the point of end-use, and

• balance 70 – 90% of energy of the power of the prime mover being converted to unusable heat energy and to a lesser extent lost in form of friction, misuse.

Thus the Knowledge of Air compressor is important for Mechanical Engineering students, Utility Managers/Maintenance Mangers.

Course covers:

1. Significance of Air Compressor in the industry & it's types

2. Air Compressor selection criteria

3. Air Compressor Capacity: Free Air Delivered (FAD)

4. Air Compressor capacity Controls

5. Effects of Localized & Operational parameters on the Air Compressor performance (Energy Consumption)

6. Compress Air leakage assessment, measurements 7 correction (Numerical ton Leakage calculation)

7. Air Compressor installation tips to the Practicing Engineers

8. Case study on the Energy Audit of the Air Compressor

Compressor Efficiency (Assessment of Compressors)

• Most practical: specific power consumption (kW / volume flow rate)

• Other methods

• Isothermal

• Volumetric

• Adiabatic

• Mechanical

Capacity: full rated volume of flow of compressed gas

• Actual flow rate: free air delivery (FAD)

• FAD reduced by ageing, poor maintenance, fouled heat exchanger and altitude

• Energy loss: percentage deviation of FAD capacity
