AB - In order to analyze the rationality of the compound well structure and the  degree of heat penetration of groundwater in a groundwater ground source  heat pump project in a certain district of a city, the author proposed a  method for building energy consumption simulation and groundwater flow  numerical model. The variation trend of groundwater temperature under  different heat transfer temperature difference is simulated and predicted.  The experimental results show that the fitting points where the error  between the simulated predicted temperature and the actual measured  temperature does not exceed 0.5ºC account for 51.7%, the fitting points  where the error is 0.5~1ºC account for 28.7%, the fitting points where the  error is 1~2ºC account for 18.1%, and the fitting points where the error is  greater than 2ºC account for 1.5%. The dynamic change trend of the simulated  predicted temperature curve is basically consistent with that of the actual  measured temperature curve. It is proved that the building energy  consumption simulation and the numerical model of groundwater flow can  effectively analyze the rationality of the compound well structure of the  groundwater ground source heat pump project and the degree of groundwater  heat penetration.
