반응표면법을 이용한 하이브리드 지열히트펌프 냉방운전 최적화 연구

The objective of this paper is to optimize the size and control strategies using an optimization methodology called as the response surface method (RSM)to decrease energy consumption (EC) of HGSHP systems. The detailed simulation of Hybrid Ground Source Heat Pump system (HGSHPs) has been conducted using the TRNSYS simulation program and integrated with the RSM for the specified building and system composition of HGSHP by comprising a cooling tower as an auxiliary heat rejecter and a boiler as an auxiliary heater. By using commercial software, which is Minitab 15, the full factorial Designed Of Experiment (DOE) has been used to analyze the main factors’ effect on EC. After analyzing the plots of main effects and interaction, the RSM with a central composite design has been adopted to draw contour plots and analyze response surface regression for determining optimal size, operation range and time of GHX loop and cooling tower loop in the cooling season.
