Experimental study of ground temperature field characteristics surrounding GSHP system in Shanghai

Combined with a ground-source heat pump project, sets up a monitoring testing field of ground temperature around ground heat exchanger, and monitors ground temperature in centers and peripheries of heat exchanging field, ground temperature near U-shape pipe wall, water temperature and flux in U-shape pipe and so on. Obtains the total quantity of heat absorption from ground and heat release to ground and COP, and emphatically analyses the distribution rules of the ground temperature around heat exchanger with time, depth and radial direction and the total changing trend.
