건물의 냉방을 위한 해수열 취득에 관한 실험적 연구

Abstract

The industrial growth and the raised living quality have led to the massive energy consumption. As a result, the polluted environment and the limited amount of energy resources emerged as serious problems to be resolved in 21st century. Especially, in the case of Korea whose imported energy dependency rate is 98.2% in 2003 and constantly increasing every year, more than 24% of overall energy consumption is for housing and commercial use. In order to cope with the shortage of natural energy resources, it is inevitable to develop alternative sustainable energy resources including seawater heat, so that they can replace existing resources. The heat transfer air velocity, 3.5 m/s is proper to consideration with the body, the pipe size 200A is more suitable than 100A due to the air velocity quantity and the ratio of pipe surface area. And the error between experimental data with simulation is below 5.34%, so the suggested equation for calculating heat transfer capacity can be used. Therefore, out of many methods utilizing seawater heat, this work presents the efficiency of using sea water heat as a resource for air-conditioners which can be converted from the outside air through the air-to-heat conversion tube. Consequently, this method provides pretty reasonable energy efficiency.
