Geothermal Heat Pumps

Analytical Models

Analytical models (i.e. computer programs) have been developed for modelling horizontal and vertical ground- coils and also for heat pump systems using ground coils as heat sources and sinks. Most of the computer programs used for ground-coil simulations involve the solution of coupled partial differential equations in two spatial dimensions marching forward in time. Solution techniques and computer requirements vary. Analytical models are generally used to develop or refine industry "rules-of-thumb" for sizing ground-coupled heat exchangers.
