In this regard, various configurations been proposed are comprehensively reviewed. They primarily based on absorption implementation multiple levels complexity flexibility. The configuration combined cycle herein has wide commercial applicability o...

This study discusses the technical, environmental, and economic feasibility of using absorption chillers driven by solar energy and/or natural gas, in selected shopping malls Barranquilla, Caribbean region Colombia. The high irradiation low prices gas cities Colombia are attractive conditions for use chillers. To prove Colombia, water/LiBr 352 kW cooling capacity was investigated considering lo...

Integrated energy systems (IES) for combined power, heat and refrigeration supply achieved a wide application due to high flexibility in matching current loading. So as electricity is easily convertible into any other form of energy, gas engines are widely applied driving characterized by electrical overall efficiency about 45% 90%, respectively. However, the highest thermal at full generated e...

The aim of this study is to analyze the feasibility single-effect H2O/LiBr absorption heat pump cycle produce combined heating and cooling. To achieve this, first, main changes that requires are described in comparison with conventional chiller. Then, cycle’s operational limits terms temperature lift LiBr crystallization evaluated. In sense, driving temperatures required for these applications ...

Biofuels have become a source of renewable energy to offset the use fossil fuels and meet demand for electricity, heat, cooling in industrial sector. This study aims (a) develop simulation trigeneration system based on gas turbine cycle an absorption chiller unit, using biomass syngas from spent coffee grounds (SCGs) replace conventional currently supplying requirements instant plant located Gu...

The environmental performance of a combined cooling, heating, and power system is analyzed in this study at component-level using SPECO-based exergoenvironmental analysis. engine consumes natural gas produces 168.6 kW net power. waste heat recovered by LiBr-H2O absorption chiller exchanger, which are used for cooling heating purposes. energy assisted solar field. An Life Cycle Assessment quanti...

The high share of buildings in energy consumption and carbon dioxide emission has led researchers to seek techniques reduce this sector. In study, considering a hot arid climate region, the wall’s heat gain was investigated. To demand, three adding PCM, combining absorption chiller with solar system dispersing nanoparticles were used results evaluated transiently. July, addition PCM building's ...

A parametric study has been carried out based on advanced exergy assessment for a parallel double-effect LiBr–water absorption chiller. The method provides the real potential of equipment improvement in system by recognizing avoidable irreversibilities. sensitivity analysis various parts destruction (endogenous avoidable, endogenous unavoidable, exogenous and unavoidable) components overall per...
