직접 냉각형 정수시스템의 결로 및 동결 방지에 관한 연구

Abstract

Abstract Water cooler, which consistently provides cold water, is exposed to dew condensation during the summer due to its high temperature and humidity. Therefore, it is foreseeable that the customers might have dissatisfaction. In addition, an experiment on freezing problem of the cooler has also been conducted in order to cope with low temperature during the winter. In this study, I first found particular parts of the water cooler that are particularly susceptible to dew condensation and freezing problem and then conducted experiments that can improve the problems. Improved factors were compared with the existing water cooler, and it is shown that improved experiments were successful. A purpose of this study is to reduce dew condensation and to prevent freezing problem. Conditions for dew condensation are set up with summer's high temperature and humidity, and the conditions for freezing experiment is set up with the same conditions that of the cold winter. Further, internal temperature and distribution of the air current of the water cooler are analyzed by the simulation.
