| Abstract | Air conditioning (A/C) systems are the major consumers of power in hot climates. In a country like Kuwait, A/C accounts for 85% of power supplied to homes during peak hours and 55% of annual energy consumption by the residential sector. A fuel-cell-based cogeneration system is proposed to improve the efficiency of generating and utilizing power for cooling in residential buildings. Distributed electric power is generated by a solid oxide fuel cell (SOFC). The electricity is used to operate high-efficiency water-cooled chillers in a district-cooling setup, which replaces packaged A/C units typically used for homes. The exhaust fuel and heat from the SOFC operate a gas turbine and an absorption chiller. A thermal energy storage tank is used for storing chilled water to reduce the total capacity of the system and, hence, capital investment. The integrated fuel-cell air-conditioning (FCAC) system improves the cooling-to-fuel efficiency, expressed as coefficient of performance, by 375%. The peak power requirement is reduced by 65% and the total fuel energy is reduced by 58%. An example system of 2 MW delivers 3750 RT (13.2 MW) of cooling to a district. Over a 9-month period, it saves 94 TJ of fuel energy and feeds 5.21 GWh of electricity to the grid as a surplus. |

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.
