Abstract
Improvement of Refrigeration system performance should be supported by increasing efficiency of its components. Mainly, two components must have excellent performance are condenser and evaporator. In this study examined a finned tube heat exchanger for evaporator application, furthermore research goal is aimed to enhance the evaporator designs in order to get higher efficiency and effectiveness of the heat exchanger. The effects of distance of fin, shape and size of the fin and combination of tube, will be investigated deeply and the heat transfer coefficient is going to examine using U-LMTD method based on some parameters of heat. This paper is still focus on design CFD model to comply the research purpose. The results were found that geometry design and meshing already compatible to get reasonable post processing results. Analysis of the air velocity vector in the heat exchanger showed good agreement toward references. Vortex and turbulence occurs in side are of the tubes and wake or stagnant flow seems in the behind tubes. The next examine is going to concern with model validation toward experimental results and investigated heat transfer coefficient in details.
