Abstract

We calculated the monthly load factor (LF) and equivalent full load hour (EFLH) using the geothermalutilization reports and the reference data for heating and cooling loads by building types. We also identified thedifference of EFLH of buildings using the real monitoring data from the GSHP system in buildings. Theconsumption of geothermal energy which is calculated by EFLH depending on building types is 54.7% of theKorean new & renewable energy supply statistical data in 2013. In case of the amount of heating energy supplyfor the newly installed GSHP system in 2013, EFLH’s is 61.6% and WGC’s is 44.5% of the result of the traditionalmethod. So, we conclude that the geothermal energy of the official statistics overestimated its actual consumption.We need to apply EFLH by building types to get more accurate and rational statistics of geothermal energyconsumption.

지열이용검토서 및 건물의 냉난방에너지 부하에 관한 기존의 연구자료를 이용하여 건물 용도별 냉난방설비의 부하율(LF) 및 연간가동등가시간(EFLH)을 계산하였다. 실제 건물에 설치된 지열히트펌프 시스템의 모니터링 자료 분석을 통해서 연간가동등가시간의 차이를 확인하였다. 건물 용도별 연간가동등가시간을 적용하여계산한 지열에너지 이용량은 2013년 우리나라 보급통계량 대비 54.7%로 계산되었다. 2013년 신규 설치된 지열히트펌프의 난방에너지 공급량 비교에서도 기존의 통계산출 방식으로 계산한 값에 비해 연간가동등가시간을이용한 경우는 61.1% 수준, WGC 방식으로 계산한 경우는 44.5% 수준이었다. 즉, 우리나라의 공식 통계는 실제지열에너지 이용량을 실제보다 과다 평가하고 있으며, 정확하고 합리적인 지열에너지 이용량 산출을 위해서는건물의 용도별 연간가동등가시간의 적용이 필요하다.
