An experimental investigation on exergy analysis of an ejector expansion refrigeration system
(INDERSCIENCE ENTERPRISES LTD, 2017)Utilisation of an ejector as an expander was experimentally investigated for an expansion work recovery in a basic refrigeration cycle. Exergy analysis was used to determine the amounts and locations of irreversibilities ... -
Can market indicators forecast the port throughput?
(INDERSCIENCE ENTERPRISES LTD, 2019)The main aim of this study is to forecast the likelihood of increasing or decreasing port throughput from month to month with determined market indicators as input variables. Additionally, the other aim is to determine ... -
Concept mapping sustainable energy management for a holistic approach to energy strategies
(INDERSCIENCE ENTERPRISES LTD, 2016)One of the important reasons for global warming and climate change is regarded as the improper management of fossil energy consumption. There may be various models or approaches to energy management (EM). However, strategic ... -
Enhanced exergetic analysis of an olive oil refining plant: evaluation of the first and second level of exergy destructions
(INDERSCIENCE ENTERPRISES LTD, 2019)Enhanced exergy analysis is built up as a novel modality to specify the origins of irreversibilities and to concentrate substantial improvement potential of components. The scope of this paper is to apply the enhanced ... -
Enhanced exergy analyses of a gas engine heat pump (GEHP) dryer for medicinal and aromatic plants
(INDERSCIENCE ENTERPRISES LTD, 2015)In this study, the performance of a gas engine heat pump (GEHP) drying system is evaluated using both conventional and advanced (or enhanced) exergetic analysis methods. The results indicated that the inefficiencies within ... -
Exergetic and sustainability performance assessment of geothermal (ground source) ejector heat pumps
(INDERSCIENCE ENTERPRISES LTD, 2012)Although ejectors have been used in cooling/refrigeration and Heat Pumps (HP) applications for a long time, utilisation of Geothermal Ejector Heat Pump (GEHP) with Ground-Heat Exchanger (GHE) is a new idea, which has ... -
Experimental exergoeconomic performance assessment of a wastewater source heat pump system
(INDERSCIENCE ENTERPRISES LTD, 2019)This study aims at experimentally analysing and assessing the performance of a wastewater source heat pump system (WWSHP) in cooling mode, which was installed at Yasar University, Izmir, Turkey through exergetic and ... -
First and second law analyses of wastewater cooled condenser for a refrigeration system
(INDERSCIENCE ENTERPRISES LTD, 2019)In this study, a vapour compression refrigeration (VCR) system with a wastewater (WW) cooled condenser at a temperature range of 27-29 degrees C was designed. The cooling capacity of the system using R134a as the refrigerant ... -
Investigation of environmental impact caused by aircraft engines
(INDERSCIENCE ENTERPRISES LTD, 2013)The environmental effects of exhaust gas emissions from different types of spark ignitions (SIs) - naturally aspirated and air-cooled from piston-prop aircraft engines - at the landing and take-off (LTO) phase of flight-based ... -
On Peng's type maximum principle for optimal control of mean-field stochastic differential equations with jump processes
(INDERSCIENCE ENTERPRISES LTD, 2019)In this paper, we investigate the Peng's type optimal control problems for stochastic differential equations of mean-field type with jump processes. The coefficients of the system contain not only the state process but ... -
Performance assessment of a polyclinic heating and cooling system in a hospital building
(INDERSCIENCE ENTERPRISES LTD, 2016)The performance of a hospital building, heated by a natural gas-fired boiler system, was assessed by using energy and exergy analysis methods in this study. The analysis was performed from the primary energy production to ... -
Performance evaluation of a mobile air conditioning unit: an exergetic approach
(INDERSCIENCE ENTERPRISES LTD, 2019)This study considers a public bus (having a capacity of 99 passengers and a volume of 69 m(3)) along with its vapour compressed mobile air conditioning (MAC) unit (utilising R134a as a refrigerant) together as a low exergy ... -
Proposing an exergy management system standard for establishing exergetically green aviation
(INDERSCIENCE ENTERPRISES LTD, 2016)In June 2011, the International Organization for Standardization (ISO) released ISO 50001, Energy Management Systems - Requirements with guidance for use while there are no exergy management system (ExMS) standards published ... -
Splitting the exergy destructions of an olive oil refining plant into avoidable and unavoidable parts based on actual operational data
(INDERSCIENCE ENTERPRISES LTD, 2016)This study focused on assessing the performance of an olive oil refinery plant (with an oil capacity of 5595 kg/h) located in Izmir, Turkey. The analysis was performed with the use of actual operational data of the system ... -
