Information
This example shows the application of the model Buildings.Fluid.Geothermal.Aquifer.MultiWell.
The system consists of two wells, a warm well and a cold well. Water is extracted from the cold well at 12°C and after passing through a heat exchanger it is injected in the warm well at 16°C. This may represent the operation of an aquifer thermal energy storage system that cools an office building with a constant load of 30 kW.
