Part 1. 북강릉 지역의 스마트팜 온실 내 지열히트펌프 이용에 따른 비용절감효과에 관한 연구

초록

Research and technological developments on smart farms with the convergence of ICT technologies are underway in agriculture. Smart farms have a significant increase in energy demand due to the larger number of facilities, sensors, and electronic devices than conventional greenhouses. The greatest energy demand among these is heating energy depending on temperature. In addition, 92 percent of energy sources depend on fossil energy and are strongly dependent on foreign countries, which could cause price instability. Therefore, this study examined the performance and economic feasibility of a heat pump compared to a diesel boiler by comparing the heating performance of the conventional diesel boiler and heat pump currently in a smart farm and analyzing its economy. The heating performance was similar, but the heat pump had a 12.34% lower energy input cost. Therefore, heat pumps were found to be good heat supply systems for greenhouses. In addition, after five years of weather data and calculation of the heating load, economic analysis showed that heat pumps have a cost savings of approximately 25.8% compared to diesel boilers.
