Abstract

This study presents an energy performance evaluation of crystal tube-ice making machines (CTIMM) using three different refrigerants include R-404A, R-134A, and R-717 incorporated three cooling types of condenser involving air cooled, water cooled and evaporative cooling system arrangements. The evaluation was conducted under tropical operating conditions. The evaluation aims to determine the optimal refrigeration setup in terms of energy performance and energy efficiency in crystal tube ice plants. A comprehensive thermodynamic model was developed using Engineering Equation Solver (EES) to simulate the refrigeration cycles and assess energy performance parameters including Coefficient of Performance (COP), and energy consumption per ton of crystal tube ice production. Model validation was conducted using empirical data gathered from ice factories in Bali Island. The findings reveal that systems using R-717 with evaporative cooling condensers offer the highest energy efficiency and lowest environmental impact, but require careful safety and design considerations. Systems using R-404A and R-134a, while safer, and demonstrated higher energy usage. For further study, a multi-criteria decision analysis can be applied to evaluate trade-offs among energy, environmental, and economic criteria. The results provide a strategic framework for selecting sustainable and cost-effective refrigerant and condenser combinations for crystal tube ice plants in tropical regions.
