“…The use of ground source heat pump (GSHP) systems can lead up to a 40% energy savings for a one year operation period compared to conventional air-to-water heat pumps (Urchueguía, et al 2008). However, when considering the system as a whole including the auxiliaries' consumption and not only the heat pump, an integrated optimal operation is required.…”

“…The main advantage of these systems consists of using the ground as a heat source/sink, depending on the operating mode, which provides a more stable temperature than air. Therefore, GSHP systems present a higher efficiency than the conventional air-to-water heat pump systems [2].…”

Coupling short-term (B2G model) and long-term (g-function) models for ground source heat exchanger simulation in TRNSYS. Application in a real installation.. Applied Thermal Engineering AbstractGround-source heat pump (GSHP) systems represent one of the most promising techniques for heating and cooling in buildings. These systems use the ground as a heat source/sink, allowing a better efficiency thanks to the low variations of the ground temperature along the seasons. The ground-source heat exchanger (GSHE) then becomes a key component for optimizing the overall performance of the system. Moreover, the short-term response related to the dynamic behaviour of the GSHE is a crucial aspect, especially from a regulation criteria perspective in on/off controlled GSHP systems. In this context, a novel numerical GSHE model has been developed at the Instituto de Ingeniería Energética, Universitat Politècnica de València. Based on the decoupling of the short-term and the longterm response of the GSHE, the novel model allows the use of faster and more precise models on both sides. In particular, the short-term model considered is the B2G model, developed and validated in previous research works conducted at the Instituto de Ingeniería Energética. For the long-term, the g-function model was selected, since it is a previously validated and widely used model, and presents some interesting features that are useful for its combination with the B2G model. The aim of the present paper is to describe the procedure of combining these two models in order to obtain a unique complete GSHE model for both short-and long-term simulation. The resulting model is then validated against experimental data from a real GSHP installation.

In order to optimize the operation of a ground source heat pump (GSHP) system, the development of dynamic models that integrate all the system components is a key factor. Particularly, the modelling of the ground source heat exchanger and its coupling to the heat pump operation becomes important. Usually, this kind of systems present an on/off operation, which makes it necessary to have an accurate prediction of both the short and long thermal response of the borehole heat exchanger (BHE). In this context, the novel B2G dynamic model was developed and experimentally validated in previous works for a single U-loop BHE. This work presents the adaptation and experimental validation of the B2G dynamic model to a novel co-axial spiral BHE configuration designed in the framework of a HORIZON 2020 European Project, GEOT€CH (Geothermal Technology for €conomic Cooling and Heating).The results show that the B2G approach applied to this specific configuration produces a model that can accurately predict the behavior of the BHE.
