Abstract: | This paper presents the modelling and experimental results of wire-and-tube condensers that are commonly used in vapour compression cycle based domestic refrigerators. A condenser was experimentally tested in a real refrigerator for some operating conditions. A simulation model was developed using the finite element and variable conductance approach, along with a combination of thermodynamic correlations. The condenser capacity per unit weight was optimised using a variety of wire and tube pitches and diameters. An optimisation factor, fo was defined as ratio of the condenser capacity per unit weight of the optimised design and the present design. The application of this factor led to an improved design with 3% gain in capacity and 6% reduced condenser weight. |
