“…However, the phreatic level is 3.5 m. So, in practice, it is expected that the surrounding soil is saturated, which would turn into higher values of the conductivity and volumetric heat capacity, as it was pointed out in [29] and [38]. Measurements of the ground undisturbed temperature were undertaken at the Geocool plant and the registered values (around 19.5 o C) were very close to the water temperature coming from the ground loop, which is around 20 o C as presented in [35] and [36]. Finally, as it can be observed in Figure 6, water temperature is measured at the inlet and outlet of each one of the six boreholes connected in parallel.…”

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.

“…The system is fully monitored by a sensor network, and the data have been collected by a data acquisition unit since February 2005. The experimental data have been deeply analyzed in [32,33]. It should be noted that, in May 2011, in the framework of another FP7 European project called Ground-Med [31], the former heat pump was replaced with a new one consisting of two compressors of the same capacity in tandem, working with R410A.…”

Ground source heat pump (GSHP) systems stand for an efficient technology for renewable heating and cooling in buildings. To optimize not only the design but also the operation of the system, a complete dynamic model becomes a highly useful tool, since it allows testing any design modifications and different optimization strategies without actually implementing them at the experimental facility. Usually, this type of systems presents strong dynamic operating conditions. Therefore, the model should be able to predict not only the steady-state behavior of the system but also the short-term response. This paper presents a complete GSHP system model based on an experimental facility, located at Universitat Politècnica de València. The installation was constructed in the framework of a European collaborative project with title GeoCool. The model, developed in TRNSYS, has been validated against experimental data, and it accurately predicts both the short-and long-term behavior of the system.
