Investigation of internal heat transfer in ejection refrigeration systems.

Number: pap. ID: 677

Author(s) : SMIERCIEW K., BUTRYMOWICZ D., KARWACKI J.

Summary

The paper deals with the experimental investigation of COP increasing due to the application of the internal heat exchanger in ejection refrigeration system at the ejector discharge line/ liquid line. The testing stand and the experimental results of investigation are present in the paper. The experimental investigation was carried out for isobutane as the working fluid therefore as a consequence the ejector operated with the superheated vapour. The efficiency of the internal heat exchanger was varied between 80% up to 100%. The application of the internal heat exchanger in tested ejection refrigeration system caused increase of COP up to 20%.
