Comparison Performance of the Elliptical Flow Condenser for a Domestic Refrigerator with Wire-on-Tube Condenser

Abstract

investigation into the performance of a novel design of condenser consisted of number of loops as elliptical shape for domestic refrigeration system and comparison with wire-on-tube condenser. The purpose of this study is designing and manufacturing a new type of condensers (Elliptical condenser) that depends on the experimental data by heat exchanger performance under various operating conditions. The experiment was conducted with a refrigerator designed to work with HFC134a, under no load and with loads (1.5,3 and 12 litters of water). The results showed that the work done by the compressor decreases with elliptical condenser, and then the power consumption also decreases about (0.3Amp to 0.5Amp). Also, the effects of shape change of the condenser were very important in enhancement heat transfer rate and reduction the frictional loss as result of reducing the pressure drop in the condenser. Therefore, the elliptical condenser can be used instead of the wire-on-tube air cooled condenser in a domestic refrigeration system.
