dc.description.abstractThe use of an ejector as an expansion device instead of an expansion valve for expansion work recovery in a vapor-compression cycle was experimentally investigated. The coefficient of performance (COP) values for both conventional and ejector systems were experimentally investigated under the same external conditions. It was observed that, although the drop in the refrigerant pressure in the evaporator of the ejector system was almost negligible, it rose as high as 133 kPa in the conventional system. Depending on the operating conditions, it was found that the work recovery in the ejector was between 14% and 17%. It was also found that the refrigeration system with an ejector as the expander exhibited a COP that was 6.2-14.5% higher than that of the conventional system. The experimental results were found to comply with the theoretical results within an error of approximately 10%. (C) 2014 Elsevier Ltd and IIR. All rights reserved.en_US
