만액식 증발기를 적용한 해수냉각시스템용 전열촉진관의 열전달 특성 연구

Abstract

The marine industry has limited marine environment related problems with the previous marine environment problems. In particular, the marine environment, unlike pollution on land, has a wide variety of regional and enduring properties, causing damage to aquatic resources. Due to global warming, it is causing serious damage to the marine fishing industry due to rising sea temperatures, rising sea surface temperature, and rising sea levels. Development of a seawater cooling system is needed to solve the problem of marine industry due to environmental problems. Furthermore, heat transfer characteristics should be studied for the enhanced tubes of a flooded evaporator used in seawater cooling systems. Based on this need, the heat transfer characteristics of the heat transfer tube of the seawater dedicated heat transfer characteristics, al-brass and copper-nickel, titanium tubes will be represented. In addition, a comparison of heat transfer characteristics to refrigerant R134a and R22 could make it an important data in the design of a flooded evaporator.
