The goal of this research program is to determine the feasibility of ground coupling for various heat pump systems, and if feasibility is confirmed, to create comprehensive and reliable design guidelines for optimal ground coupled heat pump systems. The concept is discussed. Analytical heat flow models were developed to approximately design ground coupling devices for use in solar heat pump space conditioning systems. A digital computer program called GROCS (GRound Coupled Systems) was written to model 3-dimensional underground heat flow in order to simulate the behavior of ground coupling experiments and to provide performance predictions which have been compared to experimental results. GROCS also has been integrated with TRNSYS. Both soil thermal property experiments and 12 ground coupling device experiments are underway at BNL. The latter include 4 buried tanks, 7 serpentine earth coils in various configurations, lengths and depths, and 1 group of six sealed vertical wells. One earth soil has been used to heat a house on the BNL site with no use of resistance heating.
