In this research, a combined cycle using solid oxide fuel cell system, single-stage H2O–NH3 absorption chiller and residential hot water HX, is developed for the electricity production, cooling all at same time, it studied from an exergy, energy, exergoeconomic standpoint. Performance of system under design condition analyzed mathematical model simulated. After analyzing results in initial input mode, changing current density effect utilization factor on efficiency evaluated. The result indicates that total energy 4.418 kW, exergy 37.8%. And overall irreversibility 1.650 kW. On other hand, air HX are designed as elements must be given more attention than others perspective, because they have nearly most amount price compared to parts.
