Abstract
The different time dependence of energy production and consumption often complicates the design of an effective and economical energy system. This mismatch can be reduced by storing energy. Energy production systems can then be designed more independently, taking into account technical, economical as well as environmental factors. The need for storage is pronounced with renewable energy sources, such as solar or natural heat. Also, large cogeneration systems may benefit from storage. In this study, a 3-dimensional computer simulation model for aquifer thermal energy storage systems has been presented. The model employs upwind finite difference method to simulate the flow of water and heat in an aquifer. Separate submodels for energy production and consumption are also included, enabling the simulation of total energy systems. Possible subsystems include e.g. solar collectors, heat pump, buffer storage, and heat load. Heat source with an arbitrary input pattern can also be defined. Subsystems can be connected in miscellanous ways to form the desired energy system. The purpose of the study is to use the system model to evaluate the thermal performance of different aquifer based energy systems. On the basis of the simulations, some general guidelines for the thermal design of these systems are given.
