히트펌프의 대수분할 운전 알고리즘에 따른 연간 에너지 소비량 분석

다국어 초록 (Multilingual Abstract)

Global energy consumption and greenhouse gas (GHGs) emissions are gradually increasing, and this is getting worse due to the use of fossil fuels [1]. The fossil fuels produce the energy, but they also contribute to environmental degradation by releasing pollutants that cause the air pollution and destroy the environment. This inevitable increase of energy consumption and environmental degradation are identically occurring in the building sector. To reduce the energy consumption in the building sector, the operation algorithm of heat pumps staging can be one possible solution. There have been many studies on the staging algorithm of heat pump systems. However, there is still lack of annual heating and cooling energy analysis in S.Korean energy conditions. Therefore, this study aims to analyze the annual heating and cooling energy consumption according to the application of the operation algorithm of heat pump staging. The heat pump operation control was divided into three algorithm: baseline, uniform control, and sequential control. As a result, building energy consumption depends on heat pump’s staging algorithm. There was no difference in annual energy consumption between baseline and uniform control algorithm owing to their identical part load ratio. Sequential control algorithm reduced energy consumption by 6.1% compared to baseline because different part load ratio behavior of heat pumps.
