Abstract

Ice makers are essential devices for supporting various industrial sectors that require a fast and efficient supply of ice. One key factor in determining the performance of an ice maker is the arrangement of the refrigeration system components, particularly the expansion valve and condenser cooling. This study aims to analyze the effect of variations in the expansion valve and condenser cooling rate on the performance characteristics of an ice maker, including system efficiency, ice formation rate, and energy consumption. The method used in this study was a laboratory experiment with varying expansion valve types and condenser cooling rates. Data collected included pressure, temperature, ice formation time, and electrical power consumption. Analysis was conducted to determine the relationship between expansion valve configuration and cooling rate on refrigeration cycle efficiency. The research results are expected to provide technical recommendations for selecting and adjusting expansion valves and condenser cooling systems, enabling ice cube makers to operate at optimal performance and more efficiently consume energy. These findings are also expected to serve as a benchmark for the development of similar industrial-scale refrigeration systems.
