공압구동형 슬러리아이스 제빙기의 제빙특성에 관한 실험적 고찰

In this study, ice making characteristics are experimentally investigated for the ice slurry generating system which is pneumatically operated. 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 experimentations are conducted under the various test conditions such as aqueous solution concentration, flow rate of solution and frequency of cylinder stroke. For the above experimental conditions, ice making characteristics of the slurry ice generating system are evaluated in terms of the overall heat transfer coefficient and the amount of slurry ice generation. And the experimental results show that the heat transfer rate of the system is increased as the flow rate of aqueous solution increases and the concentration of ethylene glycol decreases.
