An Industrial Utilization of Tubular Ice Production Facility towards Energy Optimization Using the Study of Initial Parameters in Production

This research is concerned with the research in developing a utilization method of a tubular ice production industry using the study of initial parameters effecting the efficiency of production. The experimental parameters studied includes the inlet water temperature, the average freezing surface temperature, the average ambient air temperature and the average ambient tubular ice machine room temperature. The inlet water temperature was found as the most significant parameter among the studied parameters. After consideration, a box type heat exchanger was created to reduce inlet water temperature. The device had been installed in a 50 ton tubular ice production machine as a prototype. This research displayed that the device could significantly reduce the inlet temperature, reduce the production time per batch, increase the production capacity, and increase the cooling load as well as the coefficient of performance (COP). The results were satisfying reduction in energy consumption as well as a short payback period of five months. The piloted results are a guideline for energy conservation and optimization for other ice factories.
