In terms of heat source of the systems, researchers prefer one type heat source usually such as hot water or steam. Some studies can be free from environment. In this study, energy and exergy analysis is performed on a double effect series flow absorption refrigeration system with water/lithium bromide as working fluid pair. The refrigeration system runs on various heat sources such as hot water, hot air and steam via High Pressure Generator (HPG) because of hot water/steam and hot air are the most common available heat source for absorption applications but the first law of thermodynamics may not be sufficient analyze the absorption refrigeration system and to show the difference of utilize for different type heat source. On the other hand operation temperatures of the overall system and its components have a major effect on their performance and functionality. In this regard, a parametric study conducted here to investigate this effect on heat capacity and exergy destruction of the HPG, coefficient of performance (COP) of the system, and mass flow rate of heat sources. Also, a comparative analysis is carried out on several heat sources (e.g. hot water, hot air and steam) in terms of exergy destruction and mass flow rate of heat source. From the analyses it is observed that exergy destruction of the HPG increases at higher temperature of the heat sources, condenser and absorber, and lower temperature of the HPG, LPG and evaporator. This destruction is maximized when hot air heat source is used and minimized with utilizing hot water heat source.eninfo:eu-repo/semantics/closedAccessDouble effect absorptionEnergyExergyHigh pressure generatorRefrigeration2. law analysisLithium-bromideThermodynamic analysisWaterLibr/h2oThermodynamicsEnergy & fuelsMechanicsExergyHigh pressure effectsIndustrial refrigerationMass transferRefrigerationSolar energySpecific heatTemperatureThermodynamicsWaste heatWaterWater absorptionAbsorption refrigeration systemCoefficient of PerformanceDouble-effect absorptionsEnergyEnergy and exergy analysisEnvironmental-friendlyFirst law of thermodynamicsHigh-pressure generatorsAbsorption refrigerationArticle0003660635000032-s2.0-849421336212130106ThermodynamicsEnergy & fuelsMechanicsAbsorption Refrigeration; Solar Cooling; Cooling Systems
