| Abstract | We evaluate innovative design, installation, and control strategies for generating combined cooling, heating, and electric power (CCHP) with fuel cell systems (FCS). The addition of an absorptive cooling cycle allows unrecovered FCS heat to be converted into cooling power, such as for air-conditioning. For example, unrecovered low temperature (80–160°C) heat can be used to drive absorption chillers to create a chilled water stream to cool building spaces. Compared with separate devices that individually generate electricity, heat, and cooling power, such CCHP FCS can reduce feedstock fuel consumption and the resulting greenhouse gas emissions (GHG) by at least 30%. We develop economic and environmental models that optimize the installed capacity of CCHP FCS to minimize either global carbon dioxide (CO2) emissions or global energy costs. Our models evaluate innovative engineering design, installation, and control strategies not commonly pursued by industry, and identify strategies most beneficial for reducing CO2 emissions or costs. Our models minimize costs for building owners consuming cooling power, electricity, and heat by changing the installed capacity of the FCS and by changing FCS operating strategies. Our models optimize for a particular location, climatic region, building load curve set, FCS type, and competitive environment. Our models evaluate the benefits and drawbacks of pursuing more innovative FCS operating strategies; these include 1) connecting FCS to distribution networks for cooling power, heat, and electricity; 2) implementing a variable heat-to-power ratio, to intentionally produce additional heat to meet higher heat demands; 3) designing in the ability to tune the quantity of cooling power from the absorption chiller compared with the amount of recoverable heat from the FCS; and 4) employing the ability to load-follow demand for cooling, heat, or electricity. We base our datum design conditions on measured data describing generator performance in-use, and on measured data describing real-time electricity, heating, and cooling demand over time. A unique feature of our data sets is that the space cooling demand is directly measured and distinguishable from electricity demand (unlike as with standard air conditioning systems). We report results for optimal installed capacities and optimal FCS operating strategies. We generalize these results so that they are applicable to a wide-range of environments throughout the world. |

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.
