초록

The GHG(Green House Gases) emitted by the building energy consumption was a serious problem to the global warming because the building energy consumption ratio was approximately 30∼40% to the all energy consumption. Recently, a lot of the building energy source Heat Pump installed for the air conditioning, the domestic water supply. Generally, the Heat Pump is classified the EHP(Electric Air-sourced Heat Pump), the GHP(Gas Engine Driven Air-sourced Heat Pump), the GSHP(Electric Ground-Sourced Heat Pump). As known, the reducing performance of GHG of GSHP is approximately 20∼25% higher than EHP and GHP. However, the published quantitative study on the performance of reducing annual GHG was rare case. Therefore, the purpose of this study is comparison of the GHG on EHP, GHP, GSHP based on conversion data of annual energy consumption of GSHP in the case building. According to this study, the GSHP GHG emission is 18.1% lower than EHP, 8.1% lower than GHP. (In this study, the fossil fuel GHG emission estimate due to the IPCC GHG estimation rule as well as the electric power GHG emission estimate due to the electric power production ratio of fuels, the efficiencies of power plant of fuels, the efficiency of electric power distribution in Korea. The case building is a child-care center of which all area is 2,119.2㎡ and GSHP capacity is 90RT and the location is Seoul Korea.)
