재생에너지 적용을 위한 국내·외 정책동향 및 시설원예산업에서의 히트펌프 적용성 분석

초록

Heat pumps are essential in maximizing the efficiency of using new and renewable energy sources and providing eco-friendly heating and cooling solutions. In this paper, the trends of domestic and foreign new renewable energy policies were analyzed, and the applicability was evaluated by analyzing agricultural application research according to the type of heat pump. In Korea, installation costs of the heat pump are relatively high, and supply rates are low. Still, it is necessary to pay attention to an alternative to reducing greenhouse gases in the heat sector for carbon neutrality. In foreign countries, a certain percentage of the heat energy consumption in buildings must be supplied through new and renewable energy, and the cost difference between facilities using new and renewable energy and fossil fuel is compensated through the support system for the difference in new and renewable heat energy. Recently, due to high oil prices, electricity usage for environmental control has increased in Korea, and it is thought that it is necessary to expand the use and distribution of heat pumps to respond to changes in the pricing policy and rate hikes for agriculture in the future. The heat pump varies depending on the heat source and method used. Various factors must be considered when installing such a heat pump. For efficient energy use, selecting a suitable heat pump according to the geographical condition to which the heat pump is to be applied and choosing an appropriate capacity for the size of the horticultural facility to which the heat pump is to be used are major. In addition, efforts to improve and optimize energy efficiency through a hybrid heat pump system in which two or more heat sources are combined are considered necessary.
