Research ArticleOpen accessIn the keywordsThermodynamic Analysis of a Marine Refrigeration Machine with AmmoniaMawhoub Soubih, Samir Zahaf, Dahmane Mouloud, Benkhettab MohamedThe purpose of this study is to present a thermodynamic modeling of a marine chiller using ammonia as a refrigerant. The modeling is based on the first and second laws of thermodynamics and the fundamental laws of heat transfer. System performance in terms of coefficient of performance, total exergy losses and exegetic efficiency, have calculated the temperatures of sea water … …American Journal of Engineering and Applied Sciences, Vol. 14, Issue 4 · 25 Nov 2021 · 6,326 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEvaluation of a Refrigeration System Based on Nano-Refrigerants and Nano-LubricantsHudaElslam A. S. Mohamed, Unal Camdali, Metin ActasMost of studies reported that disperse nanoparticles into refrigerants and lubricating oils lead to improve a coefficient of performance, due to improvement of thermal physics properties of a pure fluid, which leads to reduced energy consumption. Using nanoparticles in a refrigeration system is associated with many difficulties such as the cost of preparing and obtaining a stable and homogeneous mixture … …American Journal of Engineering and Applied Sciences, Vol. 14, Issue 3 · 12 Aug 2021 · 7,164 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAnalysis of Eco friendly Refrigerants Usage in Air-ConditionerC. Chinnaraj, R. Vijayan, P. GovindarajanProblem statement: There are two types of global warming contributions through refrigeration and air conditioning systems. The first one is the Direct Global Warming Potential (DGWP) due to the emission of refrigerants and their interaction with heat radiation. The second one is the Indirect Global Warming Potential (IDGWP) due to the emission of Carbon Dioxide (CO2) by consuming the energy … …American Journal of Environmental Sciences, Vol. 7, Issue 6 · 27 Dec 2011 · 8,462 accessesView PDFCite

One of the alternative systems that brought to agenda is the desiccant cooling systems, which may provide important advantages in solving air conditioning problems. Approach: The performance analysis of desiccant cooling with solar energy are analyzed. The system was designed, constructed and tested … …American Journal of Environmental Sciences, Vol. 7, Issue 3 · 11 Jul 2011 · 7,503 accessesView PDFCite
Review ArticleOpen accessIn the abstractTEC-Driven Mini Refrigerators: Recent Applications With Performance CharacteristicsTamer Guclu, Pinar Mert Cuce et al.Thermoelectric Cooling (TEC) technology has become a remarkable alternative in mini refrigerator applications in recent years, thanks to its lack of moving parts, silent operation, compact structure and environmentally friendly features. This study aims to examine the current usage areas, performance characteristics, and engineering challenges of TEC systems in mini refrigerator applications with a holistic approach. Experimental and theoretical studies … …Energy Research Journal, Vol. 14, Issue 1 · 23 Dec 2025 · 3,306 accessesView PDFCite
Research ArticleOpen accessIn the abstractINVESTIGATIONS ON THE PERFORMANCE OF VAPOUR COMPRESSION SYSTEM RETROFITTED WITH ZEOTROPIC REFRIGERANT R404AA. Lovelin Jerald, D. SenthilKumaranThe environmental impacts like global warming and ozone depletion has become a challenge to the refrigeration and air conditioning industry. Chloro Fluoro Carbons (CFCs) and Hydro Flouro Carbons (HCFCs) are referred to as an Ozone Depleting Substances (ODS) because once these gases are released into the environment and reach the stratosphere, depletes the ozone layer. This research paper aims to … …American Journal of Environmental Sciences, Vol. 10, Issue 1 · 11 Feb 2014 · 7,626 accessesView PDFCite
