Economical analysis of combined fuel cell generators and absorption chillers

AbstractThis paper presents a co-generation system based on combined heat and power for commercial units. For installation of a co-generation system, certain estimates for this site should be performed through making assessments of electrical loads, domestic water, and thermal demand. This includes domestic hot water, selection of the type of power generator, fuel cell, and the type of air conditioning system, and absorption chillers. As a matter of fact, the co-generation system has demonstrated good results for both major aspects, economic and environmental. From the environmental point of view, this can be considered as an ideal solution for problems concerned with the usage of Chlorofluoro carbons. On the other hand, from the economic point of view, the cost analysis has revealed that the proposed system saves 4% of total cost through using the co-generation system

Computer based selection and performance analysis of marine diesel engine

AbstractThe major steps in two-stroke diesel technology have been surprisingly few over the past century, now we have another major step – electronically controlled marine diesel engines. This paper will discuss how the use of computer helps to select diesel engines, compare between different types, increase the performance of the conventional diesel engines and generate the different performance curves for such engines
