The study is motivated by the desire to investigate if the wire-on-tube condensers used in R-12 based refrigerators could be used in a modified refrigerator using R-134a refrigerant. Experiments were conducted in a climate chamber under controlled and varying ambient temperatures and mass flow rates to determine the locations where phase change occurs and the degree of subcooling achieved. In terms of initial and final phase change point locations the predicted results agree with the experimental results to within ±10%. The analysis and the experiments also lead to the information about the adequacy of the number of tubes for complete condensation of the refrigerant vapour under given operating conditions. The methodology can be used as a design tool for the design of wire-on-tube condenser of a small refrigerator as well as the suitability of specific decommissioned condensers for use in a retrofitted refrigerator. It also indicates that R-12 based refrigerators using wire-on-tube condensers retrofitted with R-134a compressor and refrigerant deserve and warrant further studies for adoption. 2014-04-22T06:54:06Z 2014-04-22T06:54:06Z 2006 Article International Journal of Refrigeration, vol. 29(3), 2006, pages 495-504 0140-7007 http://dspace.unimap.edu.my:80/dspace/handle/123456789/33893 http://www.sciencedirect.com/science/article/pii/S0140700705001416 http://dx.doi.org/10.1016/j.ijrefrig.2005.07.001 en Elsevier Ltd.
