In this section, exergoeco- nomic analyzes are conducted for compression refrig- eration cycle components. Exergoeconomic analysis of costs rate needs to be defined by exergy in Eq. (23) [20]: C˙ k = ck E˙ xk (23) Equation (24) shows the balance of cost equations, which takes...
In this paper a methodology for the optimal integration of water/lithium bromide absorption chillers in combined heat and power plants is proposed. This method is based on the economic optimization of an energy plant that interacts with a refrigeration cycle, by using a successive linear programmin...

of the Thomas technique (Bruce et al., 1953). The energy balance equation for the catalyst pellet (Eq. 11) is solved using an implicit finite difference formulation. The equations representing the energy balances are coupled through the heat transfer terms. The material and energy balance equatio...
The article presents, the energy-exergy based performance investigation of a solar driven two-bed adsorption refrigeration system. The energy and exergy balance equation for the cooling system has been developed for this analysis. Exergy assessment measures the destruction and losses in various ...
