폐열회수 환기장치를 연계한 태양열 난방 시스템의 시뮬레이션 및 LCC 평가

Abstract

Korea in 2008, is the world's nine largest energy consuming countries, greenhouse gas emissions the world's 11th rank. Since the 1993 that joined United Nations Framework Convention on Climate Change, in 2002 Deviated from obligations to reduce greenhouse gas emissions in 2002. However, according to the agreement in Copenhagen should be reduced to 30% in 2020 Business As Usual. This is a recommendation based on IPPC(Intergovernmental Panel on Climate Change) in developing countries is the highest level. As a result, reduces to that our dependence on fossil fuels and carbon emissions the government was planning a green growth. In addition, while experiencing the need for introducing a carbon tax, as the solution to this problem is increasing interest in renewable energy sources. Renewable energy sources currently being developed country for practical application is solar energy and wind power. Biomass, geothermal, ocean energy, fuel cells use for energy that development in some areas, or put in front of commercialization. Of solar energy resources consistent with the current technological and economic advance continues, one of the most widely used renewable energy sources. Technology that uses solar energy for the solar heat energy and solar photovoltaic can be divided into two kinds of technology. Use of these technology, heating or cooling in building, hot-water supply and supply heat to processes. In this study, we use solar heat energy to heat building for heating system was studied. As the experimental site was the S corps actual workplace. In addition, the industry requires large amounts of energy consumption, occur harmful substances that threaten worker's health during the operation, considering that the heat recovery ventilation system was installed. We stored solar thermal energy to storage tank through solar collectors. Heat recovery ventilator exchange heat between return air and outdoor air. The outdoor air that is heat exchanged sent to air-handling unit, and heated by solar thermal energy stored in storage tank. Heated air is supplied to indoor room through air-handling unit. In this study, we proceed Simulation and LCC evaluation. As a result we Investigate the performance of Heat recovery ventilator, and were able to determine the economics of the solar system. Temperature was a big impact on the efficiency of the Heat recovery ventilator. A daily amount of heat recovery is 14,370 kcal/h, The amount of the accumulate heat recovery is 4,140,100 kcal. The result of Life Cycle Cost, Solar system had occurred 14 years later, the cost savings for the boiler system and EHP.
