60RT급 해수냉난방시스템의 성능특성에 관한 실험적 연구

Abstract

This study experimented on a heating and cooling system that uses the deep ocean water as a heat source in a laboratory equipped with the water intake system. Experiments on direct cooling using the deep ocean water of yearlong temperatures at 5 oC or less were performed. Experiments on heating using a heat pump system were performed with various ocean waters as heat sources including the deep ocean water at 5 oC, the surface ocean water at 10 oC, and the ground ocean water at 13 oC, among others. The comparison results between the conventional cooling systems and the direct cooling system using the deep ocean water revealed that the latter saved approximately 75.6% of the TOE and reduced the carbon dioxide exhaust by about 1.45 tCO2. The heating COPs of the surface ocean water and the ground ocean water increased by approximately 2.9% and 8.4% more, respectively, than that of the deep ocean water.ures at 5 oC or less were performed.
