초록
본 연구에서는 해수 열원 히트펌프를 이용한 순환여과식 양식 시스템과 태양광 발전의 에너지 절감 효과를 분석하는데 초점을 두고 있다. 동적 시뮬레이션을 통한 열부하 분석을 바탕으로 순환여과식 양식 시스템의 연간 에너지 사용량을 분석하고 태양광 발전 시스템 활용에 따른 에너지 절감 효과를 평가하였다. 열부하 분석 시 양식장이 위치한 해역, 사육조의 종류, 사육수의 순환율 등을 고려하였다. 또한 정전 시 사육수의 수온을 유지하기 위해 요구되는 비상전원으로서 기존 디젤 발전기 대신 에너지 저장장치를 적용할 때 운전 시간별 적정 용량 결정 방법을 살펴보았다. 이 결과는 4개의 해역 중 제주가 약 45%의 에너지 절감 효과로, 태양광 발전을 이용하여 가장 높은 에너지 절감 성능을 달성하였음을 시사한다.
Abstract
This study focuses on analyzing the energy-saving effects of the recirculation aquaculture system using seawater source heat pumps and solar power generation. Based on the thermal load analysis conducted using the transient system simulation tool, the annual energy consumption of the recirculation aquaculture system was analyzed and the energy-saving effects of utilizing the photovoltaic system was evaluated. When analyzing the heat load, the sea areas where the fish farms are located, the type of breeding tank, and the circulation rate of breeding water were taken into consideration. In addition, a method for determining the appropriate capacity for each operation time was examined when applying the energy storage system instead of the existing diesel generator as an emergency power, which is required to maintain the water temperature of breeding water during power outage. The results suggest that, among the four seas considered, Jeju should be estimated to achieve the highest energy-saving performance using the solar power generation, with approximately 45% energy savings.
