Project Charter Project Name Thermoelectric Module for Large Scale Systems Project Lead Bryan McCormick Date, Revision # Project Sponsor Dresser- Rand: Paul Chilcott Start Date 12/1/08 SDT Leader Completion Date 5/22/09 Idea Submitter Dr. Robert Stevens Current Phase Detailed Design ElementDescriptionTeam Charter Process Definition The business process in which opportunity exists. This project is aimed at acquiring an improved understanding of the workings of thermoelectric (TE) devices as a means to recovering wasted energy from Dresser- Rand turbo machinery exhausts in the form of usable power. Strategic Goal/ Business Case Describe the opportunity as it relates to strategic business goals. A clear understanding of the workings, benefits and fallbacks of thermoelectric devices is important when deciding whether it is feasible to implement this technology in industry, and whether it is the best choice among alternative technologies. Problem Statement State the significant issue(s) that needs to be addressed or opportunities to pursue. To better understand thermoelectrics and their potential applications in industry for energy recovery, it is important to have a reliable, flexible and efficient test stand to validate models. The current test stand requires long set-up times, does not provide readily available data and has too many variables that compromise the reliability of the acquired data. There are also different configurations that could be tested if the stand allowed for more flexibility, which would produce a wider range of data to draw conclusions from. Benefits Impact ($) What are the anticipated business results and when would the results be realized? Upgraded thermoelectric test rig utilizing interchangeable air- cooling on the cold side and capabilities for different configurations. Upgraded data acquisition system. Improved Power Unit. Documented data on module performance for verification of theoretical results. (All these deliverables are expected to be ready by 05/22/09) What is the preliminary budget estimate for the project cost? This project counts with a budget of $7500 Scope/Boundaries Describe the project's scope and boundaries. Describe what is in and outside the scope. Activities within scope include: 1. Implement air-cooling on cold side of thermo-electric array in addition to the water- cooling system. 2. Be able to experimentally validate thermoelectric system models and enable more parameters to be explored. 4. Improve set-up and shut- down procedures to reduce assembly times. 3. Improve user interface and data acquisition to allow greater ease of use of the test stand. The scope excludes: - Any study or design of the system that would eventually be implemented in industry.
