Within the Process and Manufacturing Sector, a major area for energy conservation via efficiency monitoring is Motor Driven Systems by electricity. This sector comprises 20 - 25 % of the world's total electrical demand. In many countries, electrical demand is responsible for about 40% of greenhouse gas emissions.
Electricity usage in Motor Driven Systems Electricity sector subdivides as follows:
Fans/ Blowers 18%
Air Compressors 17%
Cool Compressors 11%
Energy losses appear as heat. Robertson Technology has developed technology for measuring differential temperature to an accuracy of better than 1mK (0.001 Degree C), with long term stability.
This technology has been applied to the measurement of pump, water trubine and fan/blowers efficiency by the thermodynamic method ( Reference below: 1,2,3).
In pumping systems, the total possible energy savings is at approximately 40%, with the following breakdown:
Selecting a higher efficiency pump: 3%
Selecting a better-sized pump: 4%
Better Installation / Maintenance 3%
Better System Design: 10%
Better System Control: 20%
Total Possible Energy Saving: Approximately 40%
Accurate on-site measurement and monitoring is requires to achieve much of the above savings. Robertson Technology provides the relevant products and services.
