This study aims to predict the energy consumption of a water-cooled heat pump in a business office with a ground source heat pump system using a lining ground heat exchanger during air cooling with high power consumption. A model to predict COP was developed by applying a multiple regression equation using part load ratio and inlet temperature of the heat pump, which were obtained by the cooling experiment. In addition, simulations were performed to find the effectiveness of the save control systems operation on energy consumption using the model. Results suggest that energy consumption can be reduced by about 30% compared to systems without save control by optimizing the save rate.
