The use of an internal heat exchanger in vapor compression refrigeration systems one stage is a common practice because it helps to increase the cooling capacity evaporator. Furthermore, refrigerants with low global warming potential becoming more frequent due environmental regulations worldwide. Thus, this paper presents evaluation improvement produced by inclusion cycle (IHXC) experimental installation from viewpoint exergy, economic and through exergoeconomics, Specific Life Cycle Climate...
Este trabajo presenta un panorama de la influencia refrigerantes con bajo potencial calentamiento global comparados al R134a según el Impacto Total Equivalente Calentamiento (TEWI) y Rendimiento Climático durante Ciclo Vida (LCCP). Ambos parámetros son analizados para los R513A, R1234ze(E) R516A. Las pruebas se realizaron en una instalación refrigeración experimental a temperatura evaporación 0 °C dos temperaturas condensación, 35 45 °C. Para °C, R516A reducen las emisiones CO2-eq 16.0%...
CO2-based transcritical refrigeration cycles are currently gaining significant research attention, as they offer a viable solution to the use of natural refrigerants (e.g., CO2). However, there almost no papers that an exergoeconomic comparison between different configurations these types systems. Accordingly, present work deals with comparative analysis four cycles. In addition, is complemented by CO2 abatement costs. The influences variation evaporating temperature, gas cooler outlet and...
Abstract Vapor compression refrigeration systems (VCR) continue to be the most widely used type of air conditioning system for automobiles, however, they represent high energy consumption and, due use R134a as a refrigerant fluid, induce significant environmental impact. Although investigations have increased over last three decades, alternative automotive (MACs) are not yet fully developed. Among these opportunities is replacement traditional expansion device in VCR with an ejector which...
