چکیده انگلیسی
Ground source heat pump system has been widely utilized in office buildings in China. Its application in nearly zero energy office building pioneers an innovation in China. This paper focuses on real operation introduction and performance analysis of a Ground Source Heat Pump (GSHP) system in a nearly zero energy building (NZEB) with different HVAC terminal for the first time. The paper introduces the nearly zero energy building with a general presentation of its energy system, then analyzes GSHP system operation and soil temperature variation from November 2014 to September 2015 based on real operation data. The analyses manifests that the HP2# worked under an average COP of about 5.4 and 5.0 in summer and winter, respectively and HP1# worked under an average COP of 3.9 and 3.0 in winter and summer respectively. In the winter season floor and ceiling radiation system has a relatively higher performance than radiator system due to low supply water temperature going into the room. Room temperature keeps above 20 °C in the winter season and fluctuated around 26 °C in the summer season. Good room temperature and COP proves the GSHP system functions excellently. Soil temperature could recover in one year operation.
