Hydro-thermal coupled numerical simulation for groundwater storage energy and its application

Aquifer Thermal Energy Storage (ATES) Systems are used to store thermal energy seasonally, mainly for the provision of room heat and cold in buildings. According to the underground temperature-hydrologic flow coupled processes (TH) and Canada BORDEN storage energy test data, Building a TOUGH numerical model verifies the coupled processes of the mechanism in ATES. Results of the simulations appear to match the observed data well within 1°C. Besides, a practical commercial building in Shenyang on Groundwater Source Heat Pump (GWHSP) is simulated. Some problems, such as the variation and heat through of aquifer´s temperature field in 3 years and multi-wells interference and so on are analyzed and predicted. By combination of investigation data and the application of numerical models leads to a performance -enhancing design.
