A tri-generation system combining cooling, heating, and power generation can contribute to increased efficiency thereby reduce greenhouse gas emissions. This study proposed a novel concept using 100-kW polymer electrolyte membrane fuel cells (PEMFCs) as the basis for with an integrated heat pump adsorption chiller use. Three configurations of loop were designed recover waste from PEMFCs used ei...

Energy quality in each country is one of the important indicators economic development, Which affects growth that country. Exergy analysis, considering all flow properties including pressure, temperature, composition, a powerful way to evaluate energy consumption equipment such as natural gas and liquefied plants. Inefficiency system can be defined by conventional exergy analysis method, while,...

The advanced exergy analysis can identify the improved potential of each component and interaction among components refining processes. In this work, a new gasoline absorption–stabilization process (GASP) is proposed for better energy utilization considering absorption intensification, which be further explained using analysis. Both conventional GASPs are simulated in PRO/II, verified with actu...

The exergy efficiency depend upon mainly upon the inlet condition of the system because inlet condition best suit for a particular type of the system except to increase the whole system efficiency stresses are done on particular parts of system and research are done on that systems. It was observed that that every part of system has its own and equal importance because ones effect on another wh...

Exergy destruction in adiabatic pipeline flow of surfactant-stabilized oil-in-water emulsions is investigated in five different diameter pipes. The dispersed-phase (oil droplets) concentration of the emulsions is varied from 0% to 55.14% vol. The emulsions are Newtonian in that the viscosity is independent of the shear rate. For a given emulsion and pipe diameter, the exergy destruction rate pe...

This paper introduces the dual-mode refrigeration system for ice storage air conditioning. A computational model relating to the exergy loss amount and loss rate is developed in each component of the refrigeration cycle loop. A case study is presented to demonstrate the applicability of the model developed. Exergy analysis results of the refrigeration system in ice storage operating mode are co...

Although the cost allocation method does not change the total benefits of CHP, the use of various cost allocation methods generally results in significant differences in costs allocated for CHP products. In order to overcome the inadequacy of existing cost allocating methods in theory and in practice, according to the different roles of anergy and exergy in heat supply process of CHP plant, the...

On the basis of the exergy analysis, a performance optimization is carried out for a generalized irreversible refrigerator model, which takes into account the heat resistance, heat leakage and internal irreversibility losses. A new ecological criterion, named coefficient of performance of exergy (COPE), defined as the dimensionless ratio of the exergy output rate to the exergy loss rate, is pro...
