Abstract |
In this study, ice slurry generator using air cylinder was designed and manu-factured to investigate the heat transfer characteristic of the ice slurry generator. The ice slurry generator has the same shape as the shell-and-tube type heat exchanger. Refrigerant is flowing in the shell side and ethylene glycol solution in the tube side. The experiment was conducted on performance of ice slurry generator using air cylinder with standard condition and the results are plotted on the time scale. The experimental tests on the various con-centration of ethylene glycol solution, the various solution velocity in the tube side and the various tube size have been carried. For the above experimental conditions, ice making characteristics of the ice slurry generator are evaluated in terms of the overall heat transfer coefficient. And the experimental results show that the overall heat transfer coefficient of the system is increased as the tube size and the concentration of ethylene glycol decreases. |
