The purpose of Energy Savings Assessments is to identify immediate opportunities to save energy and to reduce cost, by focusing on key systems: steam, process heating, compressed air, fan,drives, lighting, and pumping systems. These processes consume most of the energy used by U.S. industry. Fine-tuning of these systems may cost little but offers your company the potential to yield large savings. Quick successes with optimizing these systems can lead to significant long-term savings if the approach is spread throughout your company's plants.
This paper discusses an energy efficient compressed air system at an industrial automation components manufacturing facility. The authors performed and energy assessment as part of the DOE's Industrial Assessment Center program and followed up with additional investigations on the compressed air system. The compressed air system utilizes an outlet pressure transducer to a microcontroller to adjust system capacity by changing motor speed and modulating an electric proportional inlet valve. This control system allows reduced modulation of operating pressure and a lower operating set point, when compared to either system alone, and avoids thermal overloads when the VFD attempts to operate at low frequencies. The control system will be examined and discussed with respect to operation, energy savings, installation costs, and payback.
The educational objectives are to train workforce to meet the nation’s need for energy efficiency and to improve the energy literacy level of the general industry. To ensure the objectives are met, the following program outcomes (PO) are defined. The students graduated from the program are expected to be able to:
- conduct complete energy assessments independently
- qualify to be certified as a lead auditor
- specialize in energy management, energy efficiency, and energy systems through our curriculum
- understand the importance of improving energy efficiency
- develop a reasonable and acceptable business case
- present energy assessment results, recommendations, and benefits orally or in writing
- work as an effective team player
- provide recommendations for improvement
To ensure that the students meet the program outcome requirements, a curriculum has been developed, which includes four courses:
- ME50101 Energy Assessment of Industrial Processes
- ME50102 Energy Management Principles
- ME50103 Industrial Energy Assessment: Tools and Applications
- ME59700 Industrial Energy Audit
The certificate program targets to the current engineers of the companies who want energy management expertise in the work place. There are two certificates for the graduates: 1) Certificate of Participation of DOE IAC, and 2) Certificate of Energy Management and Assessment from Purdue University. Students who are admitted to the Purdue Graduate Certificate Program and satisfactorily complete the four course above will receive both certificates. Undergraduate students who join the center, go through required training, and satisfactorily complete at least six real world energy assessments will receive the DOE Certificate.
Note: These four courses are transferable to the MS program if the students are qualified and decide to continue on the MS programs.
BSME/BSEEN with concentration in Energy Management
The option targets to the current students in the BSME or BSEEN programs, who want to build their careers on energy efficiency and management. These students will need to take the three lecture courses in the certificate program as a part of their Plan of Study and the last assessment project course as the Free Elective or an additional course in order to receive the concentration in Energy Management and the certification of participation from DOE.
MSME with concentration in Energy Management
The option targets to the current students in the MSME program, who want to build their careers on energy efficiency and management. These students will need to take all four courses in the certificate program as a part of their Plan of Study in order to receive the concentration in Energy Management and the certification of participation from DOE.
- Company employee with BS in an engineering discipline
- Junior or senior BSME or BSEEN students
- MS students with satisfactory graduate standing
Benefits to the Workforce
- Excellent job opportunities
- Internship opportunities
- Real world experience
Internships in companies provides excellent practice opportunities for the students. Internship will be available through the center and our school’s Office of Career Services and Professional Development.
