보일러 대수제어에 따른 사무소건물 난방에너지 절감에 대한 연구

Abstract

We proposed the operating number control of hot water boiler to save the heating energy consumption in office building. First,we split the existing boiler into two same capacity(500KW). As a result, the heating energy saving rate was 21%. And, we split the existing boiler into two capacity of 700KW and 300KW according to the heating load. In this case, the heating energy saving rate was 33%. These results presents the higher saving rates of heating energy consumption about 11% than that of the case of improving the existing boiler efficiency from 80% to 90%. Therefore, it can be said that the operating number control is more efficient way to reduce heating energy consumption than the improvement of existing boiler efficiency.
