| Abstract | Thermoelectric refrigeration offers advantages (e.g., lack of any moving parts) over other refrigeration technologies. However, because maximum performance (i.e., head load for a specified temperature drop below ambient temperature) and efficiency (i.e., coefficient of performance) are relatively low, it is important to realize them to the extent possible. Here it is shown that although the cross-sectional area of the semiconductor pellets in a thermoelectric module (TEM) does not affect performance or efficiency, it may be sized to tune TEM operating current and voltage. Then, a procedure is provided to determine the (unique) height of the semiconductor pellets and corresponding current flux through them which maximize performance. Next, it is shown that a range of pellet heights accommodates a specified performance below the maximum one and a procedure is provided to compute that corresponding to maximum efficiency. A Robin (thermal resistance) boundary condition is applied between the interface where Peltier cooling in a TEM occurs and the control point where a TEM maintains the temperature of a component or medium below ambient temperature. Robin boundary conditions are also applied between the control point and its local ambient and the interface in a TEM where Peltier heating occurs and its local ambient. The analysis is generalized by using flux based quantities where applicable and the electrical contact resistance at the interconnects in a TEM is accounted for. Flow of heat and charge are considered one-dimensional. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
