Air Compressors and Energy Saving Practices

Concepts and Practices for Energy Efficiency Improvements in Air Compressors

Air Compressor as a Utility in the industry and its Energy Saving Practices

Mechanical Eeering, Electrical Eeering, Maintenance Eeers, Utility Eeers

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 p 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 Eeering students, Utility Managers/Maintenance Mangers.

Course covers:

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

Air Compressor selection criteria

Air Compressor Capacity: Free Air Delivered (FAD)

Air Compressor capacity Controls

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

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

Air Compressor installation tips to the Practicing Eeers

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
