Title:Design of an Experimental Apparatus for Studying the Flow of Refrigerant R-134a in a Capillary Tube Refrigeration System
Author(s):Johnson, M.F.G.
Contributor(s):Dunn, W.E.
Subject(s):capillary-tube model
Abstract:This report describes the development of an experimental apparatus for testing small-bore diameter expansion devices or capillary tubes. Interest in basic refrigeration studies has increased due to the introduction of new refrigerants to replace the ozone-depleting refrigerants currently being used as accordance with the Montreal Protocol. The refrigerant considered in this report is R-134a which is the present leader for replacing R-12 for domestic refrigerator applications. The literature review discusses the limited data which exists for R-134a and the experimental apparatus developed for those studies. Also included are other capillary tube experimental apparatuses used for studying different refrigerants and the effect of suction-line heat exchange on the performance of the capillary tube. The final section of this thesis discusses some preliminary data taken using the experimental apparatus.
