Economical analysis of combined fuel cell generators and absorption chillers

This paper presents a co-generation system based on combined heat and power for com- mercial units. For installation of a co-generation system, certain estimates for this site should be per- formed 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 dem- onstrated good results for both major aspects, economic and environmental. From the environmen- tal 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.
