The Study of Coefficient of Performance and Energy Efficiency of the 50 Tons Tube Ice Maker Machine by Finding the Optimal Diameter of a Heat Exchanger Machine for Installing In the Tube Ice Maker Machine

This research is about finding the optimum heat exchanger diameter tube for consumable tubular ice production using Computational Fluid Dynamics (CFD) and apply in a 50 ton ice production facility to determine actual results. The analysis will compare six heat exchanger tube diameters from 0.5 to 3 inches using Computational Fluid Dynamics (CFD) in terms of heat transfer. It was found that the configuration using two inch is the optimum diameter for production. The results are compared to the benchmarked research made by Nakornsri et al. [1] it was able to save more energy by approximately 3.49 %. In terms of production capacity it is able to produce more than the previous referenced research by 3.24 %. The results are a guideline for energy saving to other ice factories.
