Abstract

The purpose of this study is to increase the coefficient of performance (COP) of the tube ice maker by using commercial water chillers and plate heat exchanger. The research was done by developing a mathematical model for predicting the thermal behavior of a pre-cooling system. By comparing predicted temperatures with measured temperatures, it is seen that both are agreed well and mathematical models can be used to predict thermal performance. The circulating water flow model provides a higher effectiveness ( ) at the same number of transfer units (NTU). with a certain heat capacity rate ratio of the feed water to the chilled water (wr). The pre-cooling system was tested with the tube ice machine. It was found that when the system reduces the feed water temperature to 12°C with the temperature of return water to chiller not more than that required by commercial water chillers at 12.78 °C , the batch time can be reduced by 9.1 minutes, increase overall power consumption can be reduced by 7.47 kw·h and COP can be increased from 1.89 to 2.48. This resulted could be applied to pre-cooling or pre-heating of any batch production process.
