Summary
AEEE with BEE support held a Roundtable on Energy Efficiency in Rotating Equipment on 5th August 2011 in Pune. There was overwhelming interest and high participation from companies and organisations in this field. Company spokesperson and experts from key technical organizations, made presentations. After discussions, following salient points emerged:
1. Equipment Energy Efficiency: Rotating equipment energy efficiency often gets lost within motor manufacturer, equipment manufacturer and the end user. This also results in diffusion of contribution by each in overall energy efficiency of the system. Consequently, each stakeholder is not fully involved in the emergence of energy consumption level of the combined system whether it is a pump, blower or air compressor. It is therefore necessary to establish linkage in the energy efficiency level of each sub system.
Recommendation: BEE and BIS should insist on a label which denotes the efficiency of each sub system.
2. Star labelling: For motors, star labeling has not caught on as well as it has for other equipment/appliances.This could be due to lack of response from manufacturers or due to lack of visibility of motor efficiency in equipment where motor is a part or sub system.
Recommendation:Star labels should be aligned with new standards and manufacture of lower than present EFF2 motors should be actively discouraged.
3. Indian Standards: Presently, the standards for rotating equipment particularly motors are way behind the levels obtaining in developed countries and even China who are progressing towards IE4 and IE5. In these countries, lower than minimum standard motors, for example, cannot be sold. There is a real possibility that India could become a dumping ground for low efficiency motors manufactured in China unless better standards and ban on sale of lower than allowable standards is implemented.
Recommendations:A. New standards for motors should be promulgated as soon as possible and drafting of higher standards should be commenced.
B. There should also be substantial reduction in response time for promulgating new standards.
C. Manufacturers of motors should gear up for higher standard motors and avoid resisting new levels being brought in.
4. Role of consultants: When new standards are promulgated it is seen that some project consultants continue to retain old clauses or specifications. At times, these are in contradiction as satisfying a clause of old standard may result in not meeting another specification from new standard.
Recommendation: BEE could support AEEE to conduct specific programmes for consultants involving EIL and others so that new standards are included in their specifications.
5. Development of components for EE equipment: For manufacture of energy efficient equipment it is necessary that energy efficient components or parts of rotating equipment are developed and made available. At present, there is no programme to provide the required thrust in that direction.
Recommendation: BEE could induce other agencies such as International Copper, NRDC etc to meet such requirements.
