연구용 건물의 열원 및 공조기기의 에너지 소비량 측정 및 분석

Abstract

In this study, measurement and analysis of energy consumption of a research building have been conducted. The energy audit procedure includes monitoring of electricity and LNG consumption over a period of three years from 2000 to 2002. Data acquisition system for collecting energy consumption data of HVAC equipment such as chillers, fan filter units, AHUs, cooling towers, boilers, pumps, fan coil units, air compressors and etc. has been installed in a building located in Seoul. Data collected at an interval of 1 minute are analyzed for studying the energy consumption pattern of a research building. Percentage of energy consumption of all HVAC equipment is 51.0% in 2000, 55.4% in 2001, and 62.3% in 2002, respectively. Electricity consumption of chillers accounts for 17.6% of the total energy consumption, which is the largest. Annual energy consumption-rate per unit area is 840.5 Mcal/m2.y in 2000, 1,064.8 Mcal/m2.y in 2001, and 1,393.0 Mcal/m2.y year 2002, respectively.
